Could your organization ward off an attack that is relentlessly persistent, uses thousands of agents, and may not even be directed by human actors? </p><p>Gone are the days of being able to plead you are not of interest to an attacker. You may never know why the AI breached your systems. You can&#8217;t know its motivations. </p><p>The money you have been able to save by not addressing critical vulns, sandboxing software updates, running a 24X7 SOC, encrypting everything all the time, maintaining immutable back ups (and recovery), enforcing strong authentication, and incorporating automated response, has accumulated security debt. And the bill is due.</p><p>You have to do <em>all </em>the things and you have to do it now. </p><p>That is why the industry is buzzing.

It says the intrusion was conducted &#8220;end to end&#8221; by an autonomous AI-agent system, involving thousands of automated actions, compromise of production infrastructure, credentials, and internal datasets.</p><p>Importantly, Hugging Face says:</p><blockquote><p>&#8220;We do not know which model powered the attacker&#8217;s agents.&#8221;</p></blockquote><p>The disclosure portrays what looks like an autonomous attacker controlled by some unknown party/model rather than an accident originating inside another frontier AI laboratory.

He corrected Samuel&#8217;s math, it&#8217;s actually a 74% decline from IT&#8217;s all time high of $547.50 on November 4, 2024.  Lusher correctly points out that Gartner&#8217;s woes started before ChatGPT was released with peak contract value </p><div class="callout-block" data-callout="true"><p>But here's the problem with the popular "AI killed Gartner" narrative: Gartner's GTS client count peaked in 4Q21 and has been declining for 17 consecutive quarters.  -Carter Lusher</p></div><p>That peak in Global Technology Sales  (GTS) customers was 14,149 in Q4 2021.</p><p>The most recently reported count is 11,487 in Q1 2026, reported on May 5, 2026, down 18.8%.  </p><p>There is no denying that the advent of AI is seriously impacting the value proposition of Gartner. Anyone with a $20/month subscription to ChatGPT or Claude can get instant analysis of major technology vendors and their products. Multi-page reports can be generated in minutes. The frontier models can conduct dozens of Google searches, compile hundreds of pages of data and distill an analysis in the time it takes to fill out the Gartner Inquiry form to schedule a call with an analyst four weeks out. But, as Lusher points out, Gartner started to lose clients in 2021. </p><p>What has happened over the years is a dramatic change in the information technology landscape. Where once there were a dozen players in each field now there are hundreds. Every new shift in the tech landscape only serves to multiply the available options. Case in point: the dawn of the AI age catapulted the frontier model companies from strange non-profit research labs to the most highly valued companies in the world, (albeit, still strangely organized.) </p><p>Analysts love to jump on the next new shiny toy as much as any geek. Recall the excitement over the Segway and predictions that the face of cities would be transfigured. But one layer down from frontier models are new vendors that launch with ideas about leveraging AI to accomplish old tasks. In security that means: SOC Automation, Vulnerability Management, GRC, Pen-testing, email security, and everything else. </p><p>Analyst firms have always had the luxury of waiting as markets develop. Few of their customers are early adapters so they do not get a lot of questions regarding just-launched companies. They do not have time to get briefed by the 542 AI Security vendors tracked by IT-Harvest. </p><p>I commented on Samuel&#8217;s post and have been stunned by the attention a single comment has received.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

classified under AI Security along with one MSSP. They span SOC automation, agent security, AI testing and red teaming, governance, data masking, penetration testing, managed SOC services, data center security, and endpoint controls. Descriptions are drawn from the IT-Harvest Dashboard where available, supplemented by company websites and public reporting. Headcounts are IT-Harvest figures as of July 2026.</p><h4>SOCAI</h4><p>SOCAI is an AI-powered security operations center operated by the cybersecurity department of the AIR Institute, the research organization affiliated with the BISITE Research Group. It is a service rather than a venture-backed product company: a 24/7 SOC that applies machine learning and predictive analytics to security event monitoring, covering networks, industrial control systems, mobile devices, cloud environments, and user activity. Target customers include SMEs, public sector organizations, financial institutions, healthcare, education, and energy.</p><h4>SOCNova</h4><p>SOCNova, based in Bolu, Turkey and founded in 2026, is building an AI-powered SOC platform that can run on-premise or in the cloud. The company describes a purpose-built cybersecurity AI combined with a deterministic &#8220;Evidence Intelligence Layer,&#8221; reasoning workers, threat intelligence, and automated response orchestration in a single console. Compliance with KVKK, Turkey&#8217;s data protection law, is a stated design goal, which signals a focus on the domestic market. Co-founder and CTO Onur Oktay has worked in cybersecurity for over 14 years across red team and blue team roles</p><p>Founded: 2026   |   HQ: Bolu, Turkey   |   Founders: Onur Oktay (co-founder/CTO); others not disclosed   |   Funding: None disclosed   |   Web: socnova.com</p><h4>Spacewalk AI</h4><p>Spacewalk AI, founded in 2024 in Irvine, California, builds what it calls an agentic incident commander. Rather than an alert-triage copilot, the product takes over once an alert escalates out of a SOC, MSSP, or SOAR: a commander agent coordinates specialist sub-teams and hundreds of parallel &#8220;leaf&#8221; agents on top of an internal data warehouse to investigate, map blast radius, hunt related activity, and generate reporting for different audiences. The company claims 75% faster investigations and 90% less reporting time, and holds SOC 2 Type II certification.</p><p>The founding team comes out of Obsidian Security, Mandiant, and GCHQ: Tim Wenzlau (CEO), David Elston (CTO), and Chris Fuller (CPO). CRV is among its investors, though no funding total has been disclosed. IT-Harvest counts 14 employees.</p><p>Founded: 2024   |   HQ: Irvine, California   |   Founders: Tim Wenzlau, David Elston, Chris Fuller   |   Funding: Undisclosed (CRV among investors)   |   Headcount: 14   |   Web: spacewalk.ai</p><h4>Spharaka</h4><p>Spharaka Networks, founded in 2025 with offices in Hyderabad and Bengaluru, India, is developing an AI-native autonomous cyber defense platform. Its product, Spharaka Sphere, consolidates SIEM, SOAR, XDR, and EDR functions into a single system. At its core is AuraXP, a multi-agent system built on a domain-trained cyber LLM that detects, investigates, and orchestrates responses, with a governance framework called AirWatch constraining autonomous actions within defined guardrails.</p><p>Co-founder and CEO Rajeev Raj has 19 years of industry experience; co-founder and CTO Ravikumar Nalluri comes from digital forensics and global security services. The company began generating revenue in early 2026. IT-Harvest counts 12 employees; no outside funding has been disclosed.</p><p>Founded: 2025   |   HQ: Hyderabad, India   |   Founders: Rajeev Raj, Ravikumar Nalluri   |   Funding: None disclosed   |   Headcount: 12   |   Web: spharaka.com</p><h4>Tenacium</h4><p>Tenacium, a London company founded in 2021, is older than most of this cohort and blends product with consulting. Its JEDAI (&#8221;Just Enough Data Analytics and Insights&#8221;) Situational Awareness Platform collects and fuses data from security controls to present a single view of security posture, maps enterprise risks to frameworks including NIST, CIS, ISO 27001, and CAF, and runs AI-powered investigations that prioritize security actions. Alongside the platform, Tenacium sells data and cyber consulting, deployment services, and proof-of-concept work through an Innovation Lab.</p><p>Mark Longhurst is co-founder and CTO; the leadership team claims more than 150 years of combined experience across defense, energy, and logistics. IT-Harvest counts 25 employees. No outside funding has been disclosed.</p><p>Founded: 2021   |   HQ: London, UK   |   Founders: Mark Longhurst (co-founder/CTO); others not disclosed   |   Funding: None disclosed   |   Headcount: 25   |   Web: tenacium.co.uk</p><h4>CodeIntegrity</h4><p>CodeIntegrity builds a runtime control plane that sits between AI agents and the tools, data, and production systems they touch. Every tool call is evaluated for intent, data provenance, destination, and risk, then allowed, blocked, modified, deferred, or routed for human approval. The runtime converts agent prompts into sandboxed executable control flow so each step is explicit and auditable, targeting prompt injection, tool abuse, and data leakage. It supports self-hosted and on-premise deployment. The company drew attention by demonstrating a compromise of the note-taking app Notion in under four hours, a feat noted in The Economist.</p><p>Founded in May 2024 by Steven Jung (CEO) and Abi Raghuram (CTO), who met at Rose-Hulman Institute of Technology, the company started in the Seattle area and is now listed in San Francisco. In 2026 it announced a $5 million seed round led by Syn Ventures with participation from pre-seed investors Antler and Boost VC.</p><p>Founded: 2024   |   HQ: San Francisco, California   |   Founders: Steven Jung, Abi Raghuram   |   Funding: $5M seed (Syn Ventures, Antler, Boost VC)   |   Web: codeintegrity.ai</p><h4>Novee Security</h4><p>Novee is the most heavily funded company on this list. Founded in Tel Aviv in May 2025 by veterans of IDF offensive cyber units&#8212;Ido Geffen (CEO), Gon Chalamish (CPO), and Omer Ninburg (CTO)&#8212;it raised $51.5 million within eight months: an $8.5 million seed, a $33 million Series A, and $10 million in venture debt, from YL Ventures, Canaan Partners, and Zeev Ventures. The company emerged from stealth in January 2026.</p><p>The product is a continuous, AI-powered offensive security platform: autonomous penetration testing built on a proprietary model trained for offensive security, an &#8220;Agentic Fix&#8221; capability that hands validated exploits to AI coding agents which open pull requests and then re-tests, and AI red teaming for LLM applications covering prompt injection, jailbreaks, and data exfiltration. IT-Harvest counts 58 employees and records the company as acquired by Inherent in January 2026, a transaction that has not been widely reported elsewhere.</p><p>Founded: 2025   |   HQ: Tel Aviv, Israel   |   Founders: Ido Geffen, Gon Chalamish, Omer Ninburg   |   Funding: $51.5M total   |   Headcount: 58   |   Web: novee.security</p><h4>Advai</h4><p>Advai, founded in London in 2020 by Chris Jefferson and David Sully, is one of the earliest UK companies focused on AI assurance. Its platform benchmarks AI models against task-specific performance, safety, robustness, and compliance criteria; stress-tests for edge cases and failure modes; runs adversarial testing against malicious or perturbed inputs; and monitors deployed models for drift and anomalies. Output is structured evidence usable in risk registers, governance workflows, and compliance submissions.</p><p>The company works in defence, national security, and regulated financial sectors, with the UK Ministry of Defence and the Defence Science and Technology Laboratory among named customers. Its early development was funded through multiple projects under the UK Defence and Security Accelerator (DASA) beginning in 2020. No conventional venture round has been publicly confirmed. IT-Harvest counts 35 employees.</p><p>Founded: 2020   |   HQ: London, UK   |   Founders: Chris Jefferson, David Sully   |   Funding: Not publicly confirmed; DASA-funded projects   |   Headcount: 35   |   Web: advai.co.uk</p><h4>AIM Intelligence</h4><p>AIM Intelligence, founded in Seoul in 2024, pairs an attack product with a defense product in what it calls a sword-and-shield cycle. Stinger is an automated red-teaming system that generates attack scenarios across text, image, audio, video, and robotics-related AI; Starfort is a real-time guardrail that inspects requests and responses between users, agents, and models in production, protecting personal data, source code, and credentials. The company also provides network- and endpoint-level controls for employee AI use and publishes attack taxonomies and safety benchmarks.</p><p>Co-founder and CEO Sangyoon Yu leads a team that began as student founders in AI safety research. The company raised a $1.3 million pre-Series A, then a 10 billion won (roughly $7 million) Series A in April 2026 led by Samsung Venture Investment with Mirae Asset Capital, Forest Ventures, and Smilegate Investment, bringing cumulative funding to about 12 billion won. Naver&#8217;s D2SF followed with an investment in June 2026. IT-Harvest counts 22 employees.</p><p>Founded: 2024   |   HQ: Seoul, South Korea   |   Founders: Sangyoon Yu (CEO) and team   |   Funding: ~&#8361;12B (~$8.5M) cumulative   |   Headcount: 22   |   Web: aim-intelligence.com</p><h4>Aira Security</h4><p>Aira Security, founded in San Francisco in 2025, positions itself as an enforcement layer for AI agents: discovering agentic applications in an organization, monitoring their actions, and blocking unsafe behavior in real time. Per its IT-Harvest profile, the platform processes telemetry with large-scale machine learning models to automate threat hunting and prioritize alerts, correlating signals across endpoints, networks, identities, and cloud workloads, with integrations including CrowdStrike Falcon and AWS.</p><p>Mohan Kumar is CEO. The company is five people by IT-Harvest&#8217;s count and has disclosed no funding. It has participated in the Plug and Play accelerator ecosystem.</p><p>Founded: 2025   |   HQ: San Francisco, California   |   Founders: Mohan Kumar (CEO); others not disclosed   |   Funding: None disclosed   |   Headcount: 5   |   Web: airasecurity.ai</p><h4>AliasPath</h4><p>AliasPath, registered as Contextul ME LLC in Dubai and founded in 2025, approaches AI data leakage through pseudonymisation rather than blocking. The product replaces names, addresses, and other identifiers with realistic aliases before data reaches an LLM, Copilot, or third-party processor, preserving semantic meaning so the AI still functions. Transformation is enforced at what the company calls the verification boundary&#8212;proxies, API gateways, MCP bridges, and agent tool calls&#8212;with just-in-time rehydration when a real-world action genuinely requires legal identity. It deploys via Docker at the network edge.</p><p>The company is associated with UK data-governance specialist Robert Westmacott, who previously founded Scribestar and Guardum. The IT-Harvest Dashboard lists no description, personnel, or funding on record.</p><p>Founded: 2025   |   HQ: Dubai, UAE (Contextul ME LLC)   |   Founders: Robert Westmacott (per company materials)   |   Funding: None disclosed   |   Web: aliaspath.com</p><h4>Aona AI</h4><p>Aona AI, founded in Sydney in 2023 by Bastien Cabirou (CEO) and Salim Sebkhi (CRO), sells workforce AI security: governing how employees use generative AI rather than securing models themselves. The platform discovers shadow AI across a tracked catalog of more than 5,600 tools, then enforces policy through a browser extension or desktop agent that intercepts prompts before they leave the endpoint&#8212;classifying content against data policies and allowing, redacting, or blocking it. It applies prompt-level DLP to ChatGPT, Microsoft Copilot, Gemini, and Claude, logs everything for audit against frameworks such as GDPR, the EU AI Act, and ISO 42001, and includes an employee-facing AI coach.</p><p>The company raised a small pre-seed round in June 2025 from Antler and Tenity with angels; reported amounts are modest (around US$143,000 per Tracxn). IT-Harvest counts 6 employees.</p><p>Founded: 2023   |   HQ: Sydney, Australia   |   Founders: Bastien Cabirou, Salim Sebkhi   |   Funding: Pre-seed (Antler, Tenity)   |   Headcount: 6   |   Web: aona.ai</p><h4>A Security</h4><p>A Security presents a real problem to the IT-Harvest Dashboard.  One of the defenses against someone scraping all of your data by systematically searching on each letter of the alphabet is to require three letters to be entered. A single letter name breaks our protection.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

It was founded in 2025 by Yossi Torati, Omer Gull, and Yuval Itzchakov, whose backgrounds span Check Point, Hunters, and Unit 8200.</p><p>The product is an autonomous offensive security and remediation platform: offensive and defensive AI agents continuously discover attack paths inside an organization, validate whether they are exploitable under scoped execution with full audit trails, and drive remediation at the source or through compensating controls&#8212;a bet that defenders need AI attack-path validation before adversaries chain vulnerabilities with AI themselves.</p><p>Founded: 2025   |   HQ: Israel/US   |   Founders: Yossi Torati, Omer Gull, Yuval Itzchakov   |   Funding: $37M   |   Web: linkedin.com/company/a-cyber-security</p><h4>Traceforce</h4><p>Traceforce, founded in February 2025 in San Francisco and part of Y Combinator&#8217;s Summer 2026 batch, is building AI security posture management that spans from endpoints to production workloads. The platform inventories AI-related assets and configurations, monitors how AI components are deployed, assesses exposure and misconfiguration, and correlates findings to support remediation&#8212;treating AI systems as a distinct layer of the stack whose risk needs to be separately observable. The founders describe the ambition as becoming &#8220;the Palo Alto Networks of agentic applications.&#8221;</p><p>Co-founder and CEO Xia Hua was previously director of engineering at data-protection startup Clumio; Glenn Mulvaney is the other co-founder.

Operating from Dubai and Abu Dhabi with EMEA-wide coverage, HawkEye delivers a managed CSOC and XDR service: 24/7 monitoring, threat hunting, and incident response built on a big-data analytics stack that applies regression, random forest, KNN, and naive Bayes algorithms to threat classification and prediction. Service tiers range from remote monitoring of an existing SIEM to full SOC-as-a-service, and it is one of the few regional providers offering dedicated managed SOC coverage for ICS/OT environments.</p><p>HawkEye connects to the next entry on this list: Beyon Cyber counts HawkEye AI among its offerings, reflecting Beyon Cyber&#8217;s stake in DTS Solution.</p><p>Founded: 2011 (as DTS Solution)   |   HQ: Dubai, UAE   |   Founders: Not disclosed   |   Funding: None disclosed   |   Web: hawk-eye.io</p><h4>Beyon Cyber</h4><p>Beyon Cyber, established in 2022 in Hamala, Bahrain, is the cybersecurity arm of Beyon, the holding group formed around Batelco, Bahrain&#8217;s incumbent telecom operator. It is a corporate subsidiary rather than a venture-backed startup, and at 65 employees it is the largest company in this group. Its portfolio combines proprietary platforms with managed services: Orryx AI, an AI-driven SOC platform unifying automation, analytics, and threat intelligence; HawkEye AI, an XDR and managed SOC offering with 24/7 monitoring; Intel X, a threat intelligence and rapid response service; and Complyan, a governance, risk, and compliance platform.</p><p>Alongside the platforms, Beyon Cyber runs one of the region&#8217;s larger private-sector cybersecurity operations centers and sells advisory, cyber engineering, OT/industrial security, and SOC transformation services across the GCC. Shaikh Khalid bin Daij Al Khalifa serves as CEO.</p><p>Founded: 2022   |   HQ: Hamala, Bahrain   |   Founders: Corporate subsidiary of Beyon (Batelco group)   |   Funding: Corporate-backed   |   Headcount: 65   |   Web:beyoncyber.com</p><h4>Sleuth Kit Labs</h4><p>Sleuth Kit Labs is the company behind Cyber Triage, The Sleuth Kit, and Autopsy&#8212;open-source tools that underpin a large share of the world&#8217;s digital forensics workflows. Founder and CEO Brian Carrier spent 18 years at Basis Technology leading its digital forensics group and serving as CTO before spinning the unit out as Sleuth Kit Labs in October 2023; the IT-Harvest founding date of 2016 reflects the Cyber Triage product line&#8217;s origins inside Basis. The company is based in Somerville, Massachusetts.</p><p>Cyber Triage, the commercial platform, performs remote agentless collection from Windows and Linux endpoints and memory, ingests EDR telemetry and other DFIR artifacts, and automatically scores artifacts for suspiciousness so responders can determine intrusion scope and root cause faster. Its inclusion under AI Security reflects the scoring automation now central to the product. With 6 employees and no disclosed outside funding, it is a small, product-focused operation with outsized open-source reach.</p><p>Founded: 2016 (product); spun out 2023   |   HQ: Somerville, Massachusetts   |   Founders: Brian Carrier   |   Funding: None disclosed   |   Headcount: 6   |   Web: sleuthkitlabs.com/</p><h4>ThreatLens</h4><p>ThreatLens, founded in New York in 2023 by Manoharan Mudaliar, builds a security operations intelligence platform called ThreatLens Core. The product ingests alerts and telemetry from SIEM, EDR/XDR, identity, and cloud tools and converts them into prioritized, investigation-ready incidents. Its distinguishing design choice is explainability: conclusions are presented with explicit confidence levels, contradictions, and missing evidence, and every claim traces back to specific log events. It positions itself as a non-disruptive overlay across an existing stack rather than a replacement.</p><p>Threatlens has also introduced a guardrail product for AI.</p><p>Founded: 2023   |   HQ: New

network-centric war fighting stance with little or no thought, until very recently, to the incumbent vulnerabilities that entails. </p><p>In 2011 Leon Panetta, then US Secretary of Defense, joined the chorus of those newly awakened to the reality of the threat of cyber attack against critical infrastructure when he warned of an impending &#8220;cyber Pearl Harbor.&#8221; But Panetta got his metaphor wrong. An attack against critical infrastructure of the type he and many Cassandras rail on about, one that shuts down the power and communication grids, would be more akin to a terrorist attack than a military surprise attack. The metaphor Panetta should have used was a &#8220;cyber 9/11.&#8221; A &#8220;cyber Pearl Harbor,&#8221; if the metaphor were to be correctly applied, would entail a military defeat via cyber means, which the previous chapter attempted to dramatize. In other words, an adversary&#8217;s use of computer network attack (CNA) and exploitation (CNE) to gain a tactical advantage that leads to a lost battle, a change in military standing, or even a shift in the geopolitical balance, would be most comparable to the destruction of the Pacific Fleet at Pearl Harbor, on December 7, 1941. </p><p>This book takes us on a journey from the development of the Internet, to the exciting days of the new information age, and then to the discovery of the power of networking by the US military. The history of the development of attacks against vulnerabilities in the commercial world has a parallel in the domain of governments, militaries, and war fighting; a parallel that allows us to project into the future. That future vision includes a humiliating military defeat at the hands of a more capable digital adversary. One such scenario, played out in the introduction, was chosen for a particular reason. </p><p>The 1995-96 Taiwan Straits Crisis</p><p>The history of China and Taiwan is short and consistent. When Mao Zedong finally won the Communist revolution against the Chinese Nationalists in 1949, Chiang Kai-Shek fled with his forces to the adjacent island of Formosa and established a new country, Taiwan. Since then China&#8217;s stated goal has been to reunify the two countries. Whether it will be a peaceful reunification (like that of Hong Kong in 1999) or a violent reunification, contributes to the long lasting tension between the two countries. During the Korean War there were multiple armed invasions of Taiwan from China. </p><p>In 1991 Taiwanese President Lee Teng-hui angered China with his statements about reunification, leaning away from the One China rhetoric that both countries generally stuck to. Then in 1994 Lee was traveling from South America when his flight was diverted to Honolulu to refuel. The Clinton Administration, cognizant of the delicate situation, bowed to Chinese pressure and refused to grant Lee a visa, forcing him to stay overnight in the plane. Tensions began to rise in 1995 when Lee was invited to speak at his Alma Mater, Cornell University. Congress passed a resolution requiring the State Department to grant him a visa. This was during the lead up to the first fully democratic presidential elections in Taiwan and China took a dim view of the situation. Lee spoke at Cornell in June 1995.</p><p>China announced missile tests in a region near Taiwan and began maneuvers on the mainland across the Straits from Taiwan in Fujian Provence. They carried out a series of missile launches into the sea to the North of Taiwan in July. The Clinton Administration took steps to demonstrate that the United States was willing to intercede if China threatened an invasion. In March of 1996 two aircraft carrier battle groups were deployed to the vicinity. </p><p>This is where Admiral Archie Clemins comes into the story. Clemins was the Vice Admiral of the US Navy&#8217;s 7th Fleet. Only two years before, upon achieving flag rank, he had been assigned to the training division of the US Pacific Fleet under Admiral Frank Kelso. He was also dual-hatted as head of N6, the information technology arm of the Pacific Fleet. </p><p>As an &#8220;IT guy,&#8221; Clemins began to carry a laptop with him, an unusual sight in the 1993 Navy. It was an Apple PowerBook, probably a 160 with 4 MB of memory and a 40 MB hard drive. It was one of the earliest flip top portable computers and had a grayscale LCD screen. It weighed 6.8 pounds. </p><p>His Powerbook was his constant companion, even on trips to the Pentagon. He found that people, specifically Admiral Robert J. Kelly, Commander of the Pacific Fleet based in Hawaii, were asking him for copies of the notes he took on his portable. He was living the Information Revolution of the time. &#8220;That started the use of computers, we, at Training Group Pacific, led everybody, with desktop computers.&#8221;</p><p>Shortly after taking on the Pacific Fleet role based in San Diego, Admiral Clemins got a call from the Navy&#8217;s Assignment Officer who asked how he liked the weather in San Diego and if he would like to transfer to the Pentagon? The previous week Admiral Keslo, head of Naval Operations, had announced a major reorganization of the Navy and Clemins had been chosen to lead the effort. </p><p>As Clemins pulled together a small team within the Pentagon he made sure that they used technology to its best advantage. Clemins credits this use of computers for the success his team had in accomplishing the Navy reorganization in 12 months instead of the 18 months originally slated for it. </p><p>Clemins was then appointed Deputy Commander of the Atlantic Fleet at Norfolk to accomplish the same reorganization. &#8220;The more I did this the more I came to believe this [computer technology] was the way we were going.&#8221; </p><p>From Norfolk, Clemins was promoted to commander of the 7th Fleet where he had served as chief of staff years before. He was determined to bring the fleet into the Information Age: &#8220;You have to remember the ships of the time, &#8217;93-94 are still moving information at teletype speed.&#8221; That meant at most 80 messages a day of 40 lines each. All messages would go directly to the Commanding Officer (CO) who would route them to the appropriate department or personnel. </p><p>Clemins&#8217; first task was to assemble a team. He drew from surface, air, and submarine commanders. This was 1995, the year Windows 95 came out, the first commercial operating system with embedded TCP/IP networking capability. Mark Lenci, the submarine captain that Clemins tasked with retrofitting the 7th Fleet, had little experience with networking. His only qualification: he had an AOL account. But no one in the command ranks was an expert and Clemins chose a team that could learn quickly and get things done. When Lanci reported to duty aboard Clemin&#8217;s command ship, the USS Blue Ridge, he recalls Clemins saying &#8220;let&#8217;s go take a walk.&#8221; On the flight deck he explained his vision of NCW. &#8220;I don&#8217;t know what a WAN (wide area network) is but I know we need one. Get the smart guys together here in the Pacific. We are going to do it.&#8221; And they were going to do it with commercial off the shelf products (COTS). </p><p>The Blue Ridge, the command ship of the 7th Fleet, was the first to be outfitted. Lenci relates how welders were sent on board to cut out bulkheads and toss them into the South China Sea as the Blue Ridge was steaming to port. Ships of the day had stove piped IT infrastructure. Every agency or group that needed computing power deployed their own complete stack of equipment and satellite communication gear. None of the 48 systems, all running different flavors of Unix, could interoperate and none of his team knew how to run them. The satellite antenna system looked &#8220;like a pop can with a bundle of straws strapped to it&#8221; Lenci recalls.</p><p>Lenci was deployed to Washington to scrounge funds from &#8220;end of the year&#8221; money available from budgets that had not been fully spent. He returned to Japan with $4 million available for the retrofit. He and his team began to outfit both the Blue Ridge and the aircraft carrier USS Independence with a network of Windows 95 machines. Finding bandwidth on satellite comm links proved to be difficult. Most links were controlled by the intelligence agencies and they did not want to cooperate. </p><p>So Lenci, who had spent some time at SPAWAR (Space and Naval Warfare Systems Command) called a friend in Cheyenne Mountain. He asked him for a list of all satellite transponders on geo-synchronous orbits over the Pacific theater. Of the list compiled there were seven Inmarsat satellites that were being decommissioned but still had onboard fuel so they could be repositioned. He commandeered these satellites, which to this day are still employed by the US Navy. </p><p>In very short order the beginnings of a networked fleet were accomplished. All seven shore bases (including HK, Singapore, Honolulu, and Guam) could communicate via email. The technical barrier to communications had been broken down. But, as usual with change within military structures, the biggest hurdles were getting people to change. The COs could not get comfortable with everyone in their command being able to communicate with anyone on shore or another ship. They insisted that all emails be sent to them, printed out, and distributed in the old way. </p><p>To counter this, Admiral Clemins had an &#8220;Eyes Only&#8221; email sent to each of his seven one-star admirals. The email requested their presence for an important strategy meeting in Japan. It was a test to see who actually read their email. Only four of the admirals came to the meeting. After that, the COs began to read their emails assiduously. </p><p>When China began to bluster over Taiwan, Admiral Clemins&#8217;s newly deployed systems were put to the test. The planning process for any Navy operation is cumbersome and time consuming. Multiple scenarios are proposed, researched and analyzed. The process can take days and is hampered by the communication at &#8220;teletype speeds.&#8221; When President Clinton ordered the 7th Fleet to send two carrier battle groups to the region, Clemins went into action. The Independence, shore bases, and the command ship were engaged in live communications with the Pentagon. Many options were discussed, even the possible need to enter a harbor in Taiwan. To support the deliberations a young seaman was able to pull up a live feed from a webcam focused on the harbor in question. It is telling of the interagency friction and embedded processes that the intel community objected to using such open-source data. It had not gone through the intelligence cycle&#8211;tasking, collection, analysis and reporting&#8212;after all. </p><p>At one point, and perhaps for the first time in history, Clemins used a Microsoft PowerPoint presentation, broadcast directly to the Pentagon, to help communicate the tactical situation in the region. He was interrupted by the Chairman of the Joint Chiefs who asked that a copy of the slides be expedited to the Pentagon (meaning put on a plane) Clemins instead asked the Chairman&#8217;s aide for his email address. Onscreen he pulled down the share menu and sent the PowerPoint to the General. Within minutes an aide had retrieved a hard copy and placed it in front of the General. The Chairman of the Joint Chiefs turned to the other guys, &#8220;I want this on every joint command. Now.&#8221; This was the moment when the military changed forever. Network-Centric war fighting was born.</p><p>The USS Independence was deployed to within 600 miles of Taiwan while China launched ballistic missiles into target grounds just north and south of the island nation. When the presence of the Independence did not induce the Chinese to communicate, the USS Nimitz was ordered to steam from the Gulf towards Taiwan. All of the planning and decision process took hours instead of what would formerly have taken days. </p><p>Data of the Chinese missile flights were recorded by the deployed ships. They identified the flight path and type of missile. That data was scheduled to be put on a floppy disk flown via F-14 to shore and from there by air transport back to Washington for analysis. In a brash moment Clemins had Lenci email the file via his AOL account&#8211;unencrypted&#8211; over Inmarsat and the Internet. </p><p>The successful mission deployment during the Taiwan Straits had repercussions geopolitically and for the future of the US and other military organizations. </p><p>Geopolitically, the Taiwanese were reassured that the US would stand by them. </p><p>And on China&#8217;s side: Taiwanese researcher Arthur Ding wrote: &#8220;After the crisis, China learned one lesson: the US would definitely get involved in a future Taiwan Strait conflict in one way or another, and Beijing had to be prepared as early as possible for different contingencies associated with such a scenario.&#8221; </p><p>The Navy program set in motion by Clemins, called Collaboration At Sea, is still being used. The USS Blue Ridge is still there. IT21, the Navy&#8217;s future plan for NCW was born in the Taiwan Straits Crisis. The Navy Marine Corps Internet was born. Admiral Arthur Cebrowski was bought in to articulate NCW. Admiral Bill Owens, whose son served under Lenci and eventually went on to command his own submarine, became the lead proponent of NCW and the author of <em><a href="https://www.amazon.com/Lifting-Fog-War-William-Owens/dp/0801868416">Lifting the Fog of War</a></em>, a seminal book on NCW.</p><p>Even though the Straits Crises was the most tense use of a show of force between the US and China since the Korean War, the US kept communication channels open with China&#8217;s leadership throughout. The political spin of the time led even the press to believe that two aircraft carriers had actually been deployed to steam through the Straits. In reality the aircraft carriers, while mobilized, did not intrude on China&#8217;s territorial waters and stayed well clear of the missile ranges. Similar to a chess game where two rooks are moved to dominate strategic ranks and files, the fleet movements demonstrated capability more than an actual threat. </p><p>Using the Taiwan Straits crisis as a foil for presenting a future re-enactment induced by China is not the main point of this book. The point is the impact on military thinking&#8211;on all sides&#8211;from the introduction of networking to military operations. </p><p>It is not the destruction of the power grid, or the loss of communications from attacks against the Internet and telecom infrastructure, or even the collapse of the stock market that deserves Panetta&#8217;s dire warning. Only a crippling military defeat thanks to overwhelming control of the cyber domain deserves to be labeled a Cyber Pearl Harbor. As we will see, the rapid move towards network-centric warfighting, spawned by Admiral Clemins&#8217; entrepreneurial leadership, has mirrored the move to a network-centric economy. Business learned quickly to deploy computers, email, and web browsers to take advantage of the Internet for commerce, communication, even control of critical infrastructure. Just as the business world has had to counter viruses, worms, and targeted attacks, so too has the military had its share of trouble with a networked fighting force. </p><p>As the world braces for the fallout of what is being called the Internet of Things (IoT) or as Cisco is branding it, the Internet of Everything (IoE), the military has to prepare for attacks against its &#8220;things&#8221;: Airplanes, ships, tanks, missiles, precision guided munitions, communications, satellites, and drones. </p>]]></content:encoded></item><item><title><![CDATA[There are 82 SOC Automation Startups]]></title><description><![CDATA[Is that too many?]]></description><link>https://stiennon.substack.com/p/there-are-82-soc-automation-startups</link><guid isPermaLink="false">https://stiennon.substack.com/p/there-are-82-soc-automation-startups</guid><dc:creator><![CDATA[Richard Stiennon]]></dc:creator><pubDate>Sun, 12 Jul 2026 16:11:51 GMT</pubDate><enclosure url="https://substackcdn.com/image/fetch/$s_!b7iF!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6aa5b964-027e-44fa-a3f9-5b75ccddef63_1650x900.png" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>It is a frequent refrain that there are too many cybersecurity vendors and that there will soon be a blood bath of failures. I don&#8217;t think that is the case. I  think we are missing the forest for the trees. </p><p>Most people in cybersecurity are deeply familiar with specific vendors; Microsoft, Crowdstrike, Palo Alto Networks, even Fortinet. They have years of experience with the tools these vendors sell. When confronted with the fact that there are 288 firewall vendors, 479 end point protection vendors, and over a thousand competitors to Palo Alto&#8217;s portfolio or Microsoft&#8217;s, they can&#8217;t grasp the myriad reasons why that could possibly be. </p><p>They forget the importance of geography, language, and recently the concept of &#8220;sovereignty&#8221; as applied to technology. There is a strong tendency to &#8220;buy local&#8221; that is hard to fight. Thus in Japan and Taiwan you are going to find TrendAI as the dominant endpoint protection platform. In Perth, Australia, I would not be surprised to learn that UTM vendor Red Piranha outnumbers Fortinet deployments. </p><p>Sovereignty, or country of origin became critically important after Edward Snowden revealed that the NSA had working relationships (taps) with the major US tech vendors to ingest everything. That distrust of US tech has only grown in recent years with the erratic behavior exhibited by the US. </p><p>And then there is the variation of use case, industry vertical, technology integrations, and innovation. There is always a better mousetrap. There are always special requirements. </p><p>SOC Automation, sometimes called &#8220;Agentic SOC,&#8221; is a new category only appearing after the advent of generative AI ushered in by the release of ChatGPT on November 30th, 2022.  Since then we have seen the greatest surge in cybersecurity startups ever. At IT-Harvest we track 520 AI native cybersecurity companies. They either provide protections for AI, like guardrails, governance, and model protection, or use AI to tackle security problems like email security, vulnerability management, compliance automation, red teaming, or SOC Automation.</p><p>There are 82 SOC Automation vendors. A few were headed that way before the advent of GenAI, so got a boost with new capabilities. That does not include the legacy vendors that have introduced SOC Automation tools in recent months. Will most of them fail?  I don&#8217;t think so.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

On the demand side imagine the customers of the 42,000 MSSPs in the world. All of them are candidates for switching to automation.  Or the MSSPs (like Binary Defense&#8217;s <a

You have a long-term contract with the biggest analyst firm in the world. You rely on the analyst firm to give you insights into sectors like battery technology. But that analyst firm cannot be bothered to track startups, it only tracks vendors with more than $50 million in revenue. In batteries that means Clarios, Exide, GS Yuasa, East Penn, and EnerSys, plus a handful of Chinese manufacturers. </p><p>Clarios is the latest incarnation of Johnson Controls&#8217; old battery division. I know them because I worked at the seating division in the &#8216;80s. Back then I thought JCI faced a gigantic risk. A single innovation could wipe out the entire market for lead acid batteries overnight. </p><p>It is a full time job for an industry analyst to keep track of the dozen or so vendors they track. But how can analysts answer questions about the future of their sector without researching the innovators in their space. In battery technology there are hundreds of startups to track, including: <strong><a href="https://lyten.com/">Lyten</a>, <a href="https://www.quantumscape.com/https://www.quantumscape.com/">QuantumScape</a>, Sila, Group14, Amprius, Factorial, Form Energy, EnerVenue, Redwood Materials, Ascend Elements, Mitra Chem, Addionics, TWAICE, Lilac Solutions, and EnergyX</strong>.</p><p>Bringing us back to information technology, let&#8217;s look at the cybersecurity space. Right now the space is being reinvented in real-time. Large vendors that are definitely tracked by the likes of Forrester and Gartner are all messaging around AI. But which of them has the track record of rapid innovation coupled with execution to be the trend setters in AI Security?  I would argue that none of them do. </p><p>As of this morning we track 469 AI-first vendors of cybersecurity. That is an astounding number. It&#8217;s 10% of the entire industry already. And by track I mean we monitor every investment, product announcement, and acquisition. We also track headcount for each. We look for signals in the data to guide our research. Our subscribers use our data to winnow out those signals for their own needs. </p><p>Here is the headcount chart for SOC Automation platform 7AI</p><div class="captioned-image-container"><figure><a

Which of these two is likely to get acquired first? Which competitors in these two spaces are doing as well or better? For that matter, what&#8217;s the overall growth in all the subcategories? </p><p>I am arguing that you need to collect a lot of data to answer those questions. An analyst cannot do that by taking briefings from a slice of the market. How would they even decide which vendors should get a briefing? </p><p>IT-Harvest is a four person team. We have been working on tracking the entire cybersecurity industry for the last four years. Today we track 4,092 companies and their 11,000+ products. Access to our platform give you complete visibility into what each of these vendors is doing. You can do key word searches on products, far surpassing the utility of a Google Search or a Magic Quadrant limited to ten or twelve big vendors. </p><p>Go ahead and do a Google search on &#8220;HSM&#8221;. The first three hits are for High School Musical. No vendors appear at all. The 2nd page of results only surfaces Yubico&#8217;s HSM.  Do the same search in our platform. You may be surprised to learn that there are 140 HSMs available from 70 different vendors.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img"

What they have built and are using should be a guide to any team responsible for pushing out applications. You may not have access to Mythos today, but you could be using any of the latest frontier models to get ahead of the curve so that, like Mozilla, you can swap out Mythos when you get it. I predict that by July you will have full access to models that are at least as good as Mythos for code analysis. </p><p>Here is the &#8220;advice for other projects on making good use of emerging capabilities to harden themselves against attack&#8221; that the Mozilla team put together. </p><p>They start by pointing out that just a few months ago AI was garbage at reliably identifying bugs in code. That has changed. Just read the descriptions of a few of the newly discovered bugs. </p><div class="callout-block" data-callout="true"><p>An incorrect equality check can cause the JIT to optimize away the initialization of a live WebAssembly GC struct, creating a fake-object primitive with potential arbitrary read/write in code that had undergone extensive fuzzing by internal and external researchers.</p><p>A 15-year-old bug in the &lt;legend&gt; element triggered by meticulous orchestration of edge cases across distant parts of the browser, including recursion stack depth limits, expando properties, and cycle collection.</p><p>Simulates a malicious DNS server by intercepting glibc DNS function calls in order to reproduce a UDP-&gt;TCP fallback edge case, triggering a buffer over-read and parent-process stack memory leak during HTTPS RR &amp; ECH parsing.</p></div><p>These are astounding results. Here is a <a href="https://www.linkedin.com/feed/update/urn:li:share:7458236175816933376/">statement from Stephanie Domas,</a> VP Security at Mozilla:</p><blockquote><p>The numbers tell that story better than I can. One year ago: 31 security fixes in a release. April 2026: 423. Same team. Same codebase. Completely different leverage. </p><p><br>What made this possible wasn't just dropping an AI on the Firefox source tree. The team built a real pipeline &#8212; agentic harness, dynamic test case generation, deduplication, triage, patch validation, release integration &#8212; and ran it across distributed VMs in parallel. <br><br>And the defense-in-depth work Firefox has invested in for years? It showed up. Mythos repeatedly tried to pursue prototype pollution escape paths &#8212; and was thwarted by architectural changes the team had already made. Prior hardening work compressing the attack surface, great validation.<br><br>&#8230;the future isn't unknowable chaos &#8212; it's still a race, just a faster one. I believe that more now. The economics of finding bugs have changed. The question is whether defenders move as fast as the tools let them.</p></blockquote><p></p><p>The message is clear to vulnerability teams at software companies. Get moving. Especially now that your dev teams are already using Claude Code to speed up the CI/CD cycle. </p><p>But what about vulnerability management teams at large enterprises? Yes, there will be bigger and more frequent updates coming for all of your software. You too will have to build &#8220;a real pipeline &#8212; agentic harness, dynamic test case generation, deduplication, triage, patch validation, release integration &#8212; and run it across distributed VMs in parallel.&#8221; </p><p>But get ready for the next Mythos-level evolution. Before the end of the year I predict frontier models will be identifying vulnerabilities in compiled code at such a level of accuracy that enterprise security teams are going to be severely challenged.*  They will finally have the tools to check software updates from vendors. This will stop most future Notpetyas and Solarwinds attacks. But only if a new discipline is introduced to inspect and test software updates. </p><p>According to IT-Harvest&#8217;s database of 11,400 cybersecurity products there are 241 vendors of vulnerability management solutions. Are their tools going to be fit-for-purpose by the end of the year? </p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

Mythos to find exploitable bugs in code, the same idea occurred to everyone simultaneously: Is it possible to completely evaluate a code base, fix all the vulns, and publish vuln-free code? </p><p>There is no question that would be a game changer. There remains a minor problem with actually being able to claim code is perfect. I&#8217;ll leave that to the Trustworthy Computing folks. Certainly, if you can point Mythos at your code and fix everything it finds you have produced much better code. </p><p>On Tuesday <a href="https://blog.mozilla.org/en/privacy-security/ai-security-zero-day-vulnerabilities/">Mozilla posted</a>:</p><div class="callout-block" data-callout="true"><p>As part of our continued collaboration with Anthropic, we had the opportunity to apply an early version of Claude Mythos Preview to Firefox. This week&#8217;s release of Firefox 150 includes fixes for 271 vulnerabilities identified during this initial evaluation.</p></div><p>This is it. This is the beginning of improved code across the world. </p><p>The Mozilla blog goes on to state unequivocally that computers were completely incapable of reasoning through source code a few months ago, and now they excel at it, exceeding even the best human researchers.</p><p>Historically, having egregiously bad code has had consequences in a few notable instances. Flash is practically dead. Adobe had its struggles. Microsoft Internet Explorer was forced into extinction. But there are plenty of cases of code being replete with vulnerabilities for decades and yet still winning in the marketplace. That is pretty much the story of most Microsoft products, at least early on. </p><p>Is it going to be different this time?  Mozilla was the first developer which had access to Mythos to issue a Mythos-scrubbed update. I am writing this on Firefox 150.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

The platform is built for FedRAMP HIGH and IL7 compliance and operates completely offline without cloud dependencies for classified and defense environments.</p><p><strong>Strike48,</strong> a spin-out from Devo, is an agentic log intelligence platform that unifies logs and AI to deliver comprehensive coverage, autonomous investigation, and orchestrated response. Built on 15 years of petabyte-scale log infrastructure management, the platform features a ground-up agentic architecture with three core components: a Log Intelligence Layer supporting parse-at-query and flexible deployment, Prospector Studio for building and managing custom agents without dedicated AI teams, and Agentic Packages of vetted, production-ready agents. The platform deploys purpose-built micro agents designed for specific tasks that investigate, correlate, hand off to one another, and respond autonomously across security operations, IT operations, and compliance use cases.</p><p>For security operations, Strike48 handles alert triage and threat investigation, manages workflows and incident coordination, and monitors threat intelligence feeds and security advisories. For IT operations, the platform automates incident troubleshooting, password resets, and access provisioning while identifying performance bottlenecks, monitoring cloud spending, and continuously watching infrastructure for degradation and outages. The platform offers a no-code agent builder enabling teams to design custom monitoring and automation workflows, visual orchestration combining deterministic logic with AI reasoning, real-time data visualizations, and centralized incident management. It maintains complete data isolation within customer tenants with no cross-customer model training, supports SOC2, GDPR, and SOC3 compliance standards, and provides full transparency and control over agent actions and data access.</p><p><strong>ThirdLaw</strong> provides an operational layer for enterprise AI that delivers visibility, evaluation, and control. The company makes enterprise AI safer to run and easier to control, building specifically for day-two operations. Their core capabilities include monitoring how AI is used across applications and agents, assessing AI interactions against safety and security expectations, and runtime interventions that support human review.</p><p>Their solutions address specific enterprise AI operational needs including AI investigation and response, which enables teams to link evidence across systems, preserve decision context, and route findings to existing SIEM, SOAR, and ITSM workflows. They offer AI runtime protection that enforces policy at the point of decision, making each AI decision policy-aware with outcomes based on scope and severity. Additional capabilities include agent and tool controls that govern tool execution to control risk at the moment of impact, AI data protection that prevents internal documents and restricted content from appearing in context or responses outside approved scopes, and AI governance frameworks for policy management and compliance oversight.</p><p><strong>Tropico Security</strong> operates a preemptive defense platform that predicts, deceives, and neutralizes cyberattacks before they cause damage. The platform deploys AI honeypot mazes and emulators to trap attackers in controlled environments, analyzing their tactics and techniques in real time. It detects lateral movements of ransomware using SMB and RDP emulators while stalling encryption phases to give security teams response time. The system creates a secondary Active Directory that exposes attacker tactics while protecting the real deployment, and defends Entra ID against phishing attacks. Tropico tracks stolen data on dark-web forums by feeding attackers AI-generated information instead of real company data, helping identify threat actors. The platform uses defensive phishing pages to recover compromised credentials and shut down active campaigns. It collects intelligence from multiple sources including external and internal honeypot mazes, dark-web monitoring, SIEM alerts, and client threat intelligence.</p><p>Tropico serves critical industries including banking and fintech, aerospace and defense, logistics and transportation, telecommunications, and utilities. For each sector, the platform anticipates attack campaigns, forecasts state-sponsored threats, monitors early indicators of credential theft and ransomware activity, and provides early-warning detection of cyberattacks targeting operations before escalation occurs.</p><p><strong>VisionHeight</strong> is a pre-attack intelligence and control platform designed to identify and stop threats before weaponization occurs. The platform operates through three core components: Pulse Sensors provide proprietary telemetry across worldwide datacenter IPs to detect malicious infrastructure during build-out, identifying threats 2-8 weeks before weaponization; an Infrastructure Intelligence Graph and Explainable Risk Engine map complete adversary campaigns with reason codes, confidence levels, and temporal context rather than isolated indicators; and Decision Sync integrates directly with security tools including SIEM, EDR, firewall, WAF, and identity systems to propagate policies autonomously across the security stack.</p><p>The platform provides unified, pre-attack cyber risk intelligence by fusing multiple intelligence sources &#8212; including proprietary datacenter IP signals, internal SIEM/EDR data, attack surface intelligence, and network traffic &#8212; into one verified intelligence layer. This approach addresses the problem of security teams operating with fragmented tools and high false positive rates. According to the company, VisionHeight eliminates 70-80% of VPN/CDN false positives and can reduce alert volumes significantly while surfacing actual infrastructure risks.</p><p><strong>Zepo</strong> provides an agentic social intelligence platform designed to protect organizations from AI-driven social engineering threats targeting employees. The platform enables organizations to simulate realistic, AI-powered social engineering attacks including deepfakes, voice calls, cross-platform messages, and personalized phishing to identify human vulnerabilities. It monitors employee activity in real time across multiple channels including email, chat, messaging apps, and collaboration platforms, flagging suspicious activity the moment it appears to enable organizations to act before threats escalate into actual incidents.</p><p>Zepo integrates behavioral training with live threat detection to create a unified, proactive defense layer, combining human risk assessment with immediate threat detection rather than relying solely on traditional training tools and email filters. The platform provides centralized visibility of an organization&#8217;s human risk, allowing security teams to track employee performance, identify weak points, and receive actionable metrics adapted to each employee&#8217;s behavior. Zepo&#8217;s mission centers on redefining human-centric security by addressing the gap created as attackers exploit generative AI and move toward multi-vector, personalized attacks on employees, focusing on protecting what happens at the human level rather than solely at the system level.</p><p><strong>Zynap</strong> is a preemptive cybersecurity platform that combines threat intelligence, AI agents, and automated workflows to shift security operations from reactive response to proactive attack prevention. The company&#8217;s mission is to outsmart cybercrime by delivering advanced technology and actionable threat intelligence that enables organizations to protect themselves before attacks occur, empowering enterprises and managed security service providers to stay ahead of evolving threats.</p><p>Zynap&#8217;s AI-powered platform unifies internal and external data sources to turn raw threat data into real-time, actionable foresight, tracking over 900 threat actors, monitoring more than 25,000 victims of tracked campaigns, identifying over 300,000 CVEs, and maintaining records of more than 20,000 exploits and proofs of concept.

The company&#8217;s tagline &#8212; &#8220;Checkmate, insider threat&#8221; &#8212; reflects its mission to solve the blind spots left by traditional data loss prevention and behavioral analytics tools. Above Security raised $50M to build a suite of agents that address distinct threat scenarios: the Data Exfiltration Agent connects behavioral signals, permissions, and contextual data into a unified, human-readable picture of potential data theft; the Inappropriate Use Agent identifies policy violations and misuse patterns while favoring coaching over punitive action; and additional agents monitor for behavioral drift and employee churn risk. The platform&#8217;s core philosophy is that &#8220;comprehensive security comes from understanding intent,&#8221; positioning it as a solution for organizations that need to distinguish malicious insiders from negligent employees without creating friction for legitimate users.</p><p><strong>Ntur</strong>, operating under the product name Agent Vault, provides a zero-trust security platform designed specifically for agentic AI systems. As enterprises deploy AI agents with access to tools, APIs, and sensitive data, Ntur addresses the new attack surface these agents create. The platform&#8217;s operating principle &#8212; &#8220;never trust, cryptographically enforce&#8221; &#8212; extends zero-trust architecture into the AI agent layer by cryptographically enforcing tool execution policies rather than relying on behavioral trust assumptions. Agent Vault monitors for behavioral drift in AI agents, flags deviations from expected execution patterns, and guarantees compliance with enterprise policy frameworks. The platform is built for regulated industries where AI agents must operate under strict governance, providing security teams with visibility into agent actions, tool invocations, and access patterns across the agentic stack.</p><p><strong>Aether AI </strong>delivers continuous, AI-powered penetration testing designed to outpace AI-enabled adversaries. The company positions its platform as the &#8220;world&#8217;s most dangerous Attack AI, defending you&#8221; &#8212; an offensive AI system turned toward defensive purposes that operates continuously across internal and external attack vectors. Built on more than 15 years of experience breaching hardened targets, Aether AI claims to identify more vulnerabilities than human penetration testers and operate faster than traditional red teams, at a fraction of the cost of manual testing engagements. The platform covers the full attack surface &#8212; network, application, identity, and cloud &#8212; running simulated attacks on an ongoing basis rather than in periodic point-in-time assessments. Certain advanced capabilities are currently restricted to organizations operating within Five Eyes (FVEY) allied countries, reflecting the platform&#8217;s classification-relevant origins and the sensitivity of some of its offensive techniques.</p><p><strong>CyberAGI</strong> markets its platform, branded Excalibur, as an &#8220;AI Security Department in a Box&#8221; &#8212; a self-contained security operations and offensive testing system that runs entirely within the customer&#8217;s own infrastructure. Excalibur is deployed on NVIDIA DGX Spark hardware, giving it local AI compute without requiring data to leave the customer environment, a design the company emphasizes as providing private AI with zero data exfiltration risk. The platform features a living threat risk map that continuously models attack paths and identifies choke points across the organization&#8217;s environment, allowing security teams to visualize where adversaries are most likely to move and which controls are most strategically valuable. Excalibur includes pentest orchestration capabilities that enable repeatable, scheduled attack simulations, visual evidence reporting through a Notion-like editor for documenting findings in a shareable format, and a CISO dashboard providing executive-level risk visibility. The platform is designed for security teams that want offensive and defensive capabilities unified in a single air-gapped deployment without dependency on cloud-based AI services.</p><p><strong>Hackerdogs</strong> positions itself as a &#8220;Chief Intelligence Partner&#8221; for organizations that need decision-grade threat intelligence rather than raw data feeds. The platform deploys autonomous AI agents that actively pursue answers to security questions &#8212; probing internal and external sources, correlating findings, and delivering evidence-backed intelligence &#8212; rather than simply aggregating and analyzing existing data. Core capabilities include one-click attack surface discovery that maps an organization&#8217;s external exposure, continuous scheduling of intelligence collection runs, and autonomous AI agent probing that operates without manual analyst tasking. Hackerdogs integrates with Claude and the Model Context Protocol (MCP), allowing security teams to query the platform through conversational interfaces and pipe intelligence directly into their existing toolchains. The platform is built on the premise that traditional threat intelligence tools produce too much noise and too little actionable signal, and that AI agents capable of pursuing targeted intelligence objectives can replace much of the manual analyst work involved in staying ahead of adversaries.</p><p><strong>Threat-Watch</strong> is a managed security service provider that offers to &#8220;replace your entire cybersecurity department minus the CISO&#8221; &#8212; providing comprehensive outsourced security operations for organizations that lack the resources to build in-house security teams. The service is powered by Xcitium zero-trust EDR technology and ConnectSecure for attack surface management, combining endpoint protection with continuous vulnerability visibility. Threat-Watch&#8217;s service portfolio includes 24/7 SOC threat detection and monitoring, managed incident response, compliance consulting for ISO 27001 and NIS2 frameworks, and employee phishing simulation and security awareness training. The company backs its MDR service with a $1 million ransomware breach warranty, providing financial accountability for the coverage it delivers. Threat-Watch is designed for small and mid-sized enterprises that need enterprise-grade security capabilities but cannot justify the headcount or tooling costs of a fully staffed internal security function.</p><p><strong>PurpleSec</strong> is an adaptive AI security company founded in 2019 by veterans with Department of Defense training, focused on securing AI systems and the organizations that build them. The company&#8217;s flagship innovation is PromptShield&#8482;, an intent-aware AI protection layer that analyzes prompts and AI interactions for malicious intent, jailbreak attempts, and policy violations before they reach the underlying model. PurpleSec&#8217;s product suite spans both AI-native security and traditional enterprise security: the AI Firewall provides runtime protection for AI deployments; the Prompt Analyzer allows security teams to evaluate prompt inputs for risk; the AI Security Framework offers governance and compliance guidance for AI programs; and a Free AI Risk Assessment helps organizations baseline their exposure. On the managed services side, PurpleSec offers a Virtual CISO program and Managed XDR for broader security operations. The company targets AI builders, systems integrators, and enterprises navigating the security implications of deploying generative AI in production environments.</p><p><strong>SOC Jedi.ai </strong>is an AI SOC analyst platform designed to conduct alert investigations with the speed and accuracy of an experienced Level 1 analyst &#8212; automating 90% of L1 triage work and providing 24/7 coverage without analyst fatigue. The platform operates through a pipeline of specialized agents: an orchestrator agent ingests incoming alerts, scores them using prior investigation verdicts, filters noise, and forwards unique threats for deeper analysis; a malware analysis agent decodes and decompiles files, analyzes code logic and behavior, detects malicious patterns, and issues risk reports; an attack surface agent performs continuous asset discovery, simulates attack paths under safe testing conditions, prioritizes findings by business risk, and delivers actionable remediation reports; and a dark web monitoring agent tracks leaks by corporate domain, correlates and classifies exposures, and aids deep leak investigations. Underlying the agent layer is a four-stage processing pipeline: alert data collection from SIEMs, data lakes, log managers, and REST APIs; enrichment via aggregation, threat feeds, IOC matching, and RAG; analysis for correlation, attack chain mapping, and incident summarization; and investigation delivery providing full narrative reports on what happened, how, and what to do next. The platform operates entirely within the client&#8217;s secure environment, is customizable to integrate with existing security tools and workflows, and is designed for rapid deployment with minimal setup overhead.</p><div><hr></div><p>That wraps up the promised updates to <em><a href="https://www.amazon.com/Guardians-Machine-Age-Security-Digital/dp/1945254165/">Guardians of the Machine Age: Why

vendors that were added to IT-Harvest&#8217;s research coverage after <em><a href="https://www.amazon.com/Guardians-Machine-Age-Security-Digital/dp/1945254165/">Guardians of the Machine Age</a></em> went to print. They are presented alphabetically so that you can easily compare to the Directory of 378 vendors in Appendix IV. </p><p><strong>Jazz</strong> is an AI-native Data Loss Prevention (DLP) platform that detects and prevents unauthorized data movement across an organization&#8217;s environment. The platform captures activity across entire environments to uncover all data loss vectors and features an agentic investigator called Melody that analyzes events to deliver pre-investigated answers with context, rather than generating high volumes of alerts.</p><p><strong>LangGuard.AI</strong> discovers and classifies AI assets and agents across an organization, providing IT visibility into AI systems that aren&#8217;t tracked in existing records. The platform provisions and approves vetted AI agents for enterprise use while continuously monitoring their behavior to identify incidents and audit findings through behavioral analytics, activity monitoring, and audit log retention with replay capabilities.</p><p>Operating as an AI Control Plane for IT and Security teams, LangGuard.AI interprets AI agent intent at runtime and evaluates it against enterprise policy to determine whether actions should be allowed, modified, or blocked. It enforces controls on access, tools, data, identity, and cost, while generating immutable audit logs and reports that support compliance requirements including ISO 42001, NIST AI-RMF, EU AI Act, and SOX. </p><p><strong>Lunar.dev </strong>provides an enterprise gateway for governing AI applications and agents, with strong emphasis on MCP security, tool governance, observability, and policy enforcement. The platform is designed to give security and IT teams centralized control over agent access to enterprise systems while supporting self-hosted deployment, auditability, and safer rollout of AI tools.</p><p><strong>Manifold</strong> is an AI Detection &amp; Response (AIDR) and Governance platform that secures endpoints and monitors agent behavior at runtime. The platform provides full runtime visibility into what AI agents actually do, including the tools they call, the systems they access, and the actions they take. It delivers a real-time map of every agent in an environment, their connections to MCP servers, databases, and external systems, with anomalies flagged the moment behavior drifts from normal activity. Manifold enables security teams to detect threats in real-time, define normal agent activity, and recognize risky behavior. The platform deploys in days without requiring new architecture, gateways, or proxies, and leverages existing infrastructure.</p><p><strong>Mave</strong> offers an Agentic SecOps Platform that uses AI agents to continuously detect, investigate, and triage across security stacks. The platform treats alerts as hypotheses rather than conclusions, delivering root-cause verdicts with complete audit trails and evidence-based outcomes. It continuously runs threat-hunting coverage tests across environments, adapting as the stack and adversaries evolve to prevent new tactics from becoming blind spots. Users can act directly from investigations, then automatically document and push outcomes back into existing tools like cases, tickets, and SIEM notes for fast, consistent, and repeatable response. The platform allows natural language questions across connected systems to get unified, evidence-backed answers without manual pivots or ad-hoc searching. It includes approval gates for actions and changes, fine-grained API permissions across platforms, and complete audit trails showing exactly what agents queried, how they correlated data, and what they concluded. Mave&#8217;s mission is to elevate SIEM operations by simplifying, automating, analyzing, monitoring, and optimizing them.</p><p><strong>Ntur AI</strong> is focused on securing agentic AI systems through its Agent Vault platform, which applies zero-trust and cryptographic enforcement to tools, memory, and access flows. Its positioning centers on giving enterprises stronger control over autonomous agents by blocking unauthorized tool use, protecting RAG data, and reducing credential exposure in production environments.</p><p><strong>Pallma AI</strong> provides an agent security platform designed to give enterprises visibility and control over autonomous AI systems. The company focuses on discovery, monitoring, and runtime policy enforcement so organizations can detect weaknesses early, govern agent decision-making and tool use, and contain prompt-injection or misuse risks before they affect production workflows.</p><p><strong>Plerion </strong>provides unified cloud security across code, cloud infrastructure, and AI deployments, focusing on identifying and prioritizing genuine security risks rather than best practices. The platform delivers comprehensive security coverage across three domains: code security that catches risky code patterns before deployment across GitHub, GitLab, and Bitbucket; cloud security that provides visibility into security posture across AWS, Azure, GCP, and Kubernetes environments; and AI security that detects shadow AI deployments and manages data leakage risks across platforms like Bedrock, OpenAI, and Anthropic.</p><p><strong>Pluto Security</strong> is focused on securing the enterprise AI workspace, helping organizations monitor and govern the rapidly expanding use of AI building tools across employee environments. Its positioning centers on enabling innovation while reducing the blind spots and attack surface created when workers adopt AI tools and build without centralized security oversight.</p><p><strong>RemoteThreat</strong> is an offensive-AI cyberwarfare company focused on readiness for large-scale, AI-enabled cyber conflict. Its positioning centers on helping organizations understand and prepare for the ways AI can speed vulnerability discovery, exploitation, and attack operations through training, simulation, and related programs.</p><p>Here is a chart that includes Funding in millions of dollars and Headcount.

detecting, investigating, and remediating security incidents. The platform uses agentic intelligence and swarms of AI agents to autonomously analyze findings from across an organization&#8217;s entire security ecosystem. It integrates with over 100 tools spanning identity, cloud, endpoint, network, and data security solutions including SIEM platforms, SOAR systems, EDR solutions, NDR systems, IAM platforms, and cloud infrastructure providers.</p><p><strong>Armadin</strong> builds an AI-powered offensive security platform combining human expertise with advanced technology to defend complex organizations. The platform operates as a continuous, agentic red teaming and remediation solution designed to identify and address security vulnerabilities through autonomous AI agents. The company focuses on offensive security capabilities to combat AI-driven hyperattacks, offering automated penetration testing, red team operations, and vulnerability remediation. The platform answers the core question of organizational security posture by providing unified, scalable, and ongoing offensive assessments that simulate attacker behavior at scale. It <a href="https://finance.yahoo.com/news/armadin-secures-record-breaking-189-100500253.html">announced </a>total funding of $189.9 million on March 10.</p><p><strong>Astelia </strong>is an AI-native exposure management platform that identifies vulnerabilities that are truly reachable and exploitable within an organization&#8217;s environment, eliminating noise from theoretical risks. The platform delivers three primary capabilities: network topology mapping that integrates with infrastructure and network tools to understand the complete network landscape, agentic vulnerability analysis that uses AI agents trained by nation-state-level experts to identify exploitability requirements, and reachability analysis that correlates network topology, asset context, and runtime data to classify which vulnerabilities pose genuine risk.</p><p><strong>Ciphero</strong> is an early-stage enterprise AI security vendor offering an AI verification layer that monitors, verifies, and governs human and agentic AI interactions. Founded in 2025 by the former Fakespot leadership team, the company focuses on shadow AI visibility, policy enforcement, and data-loss prevention for enterprise AI deployments, and launched from stealth with $2.5 million in pre-seed funding in late 2025.</p><p><strong>C1</strong> is an AI-native identity security platform focused on governing access for human, machine, and AI identities. Rebranded from ConductorOne in 2026, the company combines identity governance, just-in-time access, dynamic controls, and automation in a single platform aimed at modernizing legacy identity stacks for cloud and agentic enterprise environments.</p><p><strong>CyberAGI </strong>is an early-stage offensive security startup developing Excalibur, an AI-native platform for threat modeling, pentest workflow automation, and related security operations use cases. The company promotes a broader vision of building an &#8216;AI enterprise,&#8217; but its current market presence appears centered on self-serve and private-deployment offensive security tooling, with limited independent public evidence so far on funding or customer scale.</p><p><strong>EnforceAuth</strong> is a unified enterprise authorization platform that enforces fine-grained policy across infrastructure, applications, data, and AI workloads. The company&#8217;s core objective is to solve the fragmentation problem where enterprises operate with disconnected access control systems across different environments. EnforceAuth is specifically designed for AI-driven enterprises, treating AI models, prompts, tools, and agents as first-class security subjects. It controls every AI-agent-to-data and agent-to-agent interaction in real time across any cloud or infrastructure, addressing new security challenges like prompt injection and unauthorized data access by AI systems.</p><p><strong>Evoke</strong> secures the agentic workforce by providing visibility and control over every agent, action, and connection across enterprises. The platform auto-discovers agents, models, tools, and data sources to eliminate shadow AI. It identifies malicious skills and model context protocols (MCPs), maps attack paths and toxic flows, and remediates over-permissioned agents through threat modeling. The platform detects, prevents, and responds to unauthorized actions by monitoring all prompts, tool calls, and responses, enforcing per-agent policies and detections, and blocking unauthorized actions in real-time. Evoke meets agents where they live through multiple deployment architectures including endpoint agents for local environments, SDK and proxy API integrations for production agents, and browser extensions for SaaS agents. The company was selected for the 2026 CrowdStrike, AWS &amp; NVIDIA Cybersecurity Startup Accelerator and raised $4 million in pre-seed funding.</p><p><strong><a href="https://flintx.ai">FlintX</a> </strong>provides AI-powered security monitoring and threat detection specifically designed for industrial control systems and operational technology networks across critical infrastructure sectors. The company&#8217;s primary mission is to protect critical infrastructure by combining operational technology expertise with artificial intelligence to defend industrial control systems (ICS), SCADA systems, PLCs, and related environments from cyber threats.</p><p><strong>Hackerdogs</strong> is an early-stage AI-native cyber intelligence vendor that combines attack-surface discovery, OSINT, and cross-domain threat analysis into evidence-backed intelligence briefings for security and executive stakeholders. Founded by former Sumo Logic and LogicMonitor executive Tej Redkar, the company is positioning around autonomous, intelligence-led cyber exposure management, though public third-party evidence on funding and customer scale remains limited.</p><p>By next week we should be all caught up.

That was when Microsoft <a href="https://www.aol.com/news/microsoft-openai-plan-100-billion-173559025.html?utm_source=chatgpt.com">announced plans </a>for an astounding $100 billion investment in AI data centers. (The projected cost for Stargate has since been bumped up to $500 billion.) </p><p>At that time I was asked &#8220;what could possibly make AI worth $100 billion to Microsoft?&#8221;  My answer: imagine if Microsoft could find and fix ALL of the vulnerabilities in its software? That would easily be worth $100 billion.  Instead of being the root cause of all of our security issues Microsoft could be the secure option for software products. The total annual cost imposed on the world for Patch Tuesday is estimated to be as high as $225 billion according to a model I had ChatGPT construct. Should Microsoft spend $100 billion to save its customers $225 billion a year? Yes.</p><p>An AI with those capabilities is here. Only it is not an OpenAI model, it is Claude Mythos Preview from Anthropic.

The latest models from OpenAI and Anthropic were released in February. They were created using earlier versions of themselves. The <a href="/__u/stiennon.substack.com/p/how-does-an-intelligence-explosion">Intelligence Explosion</a> is happening. </p><p>Mythos is in &#8220;Preview&#8221; because in developing the model to be the next generation of general purpose LLMs Anthropic realized it was very good at discovering vulnerabilities in code and chaining together multiple vulns to create sophisticated exploits. </p><p>A couple of examples: </p><p>Somehow take a blind SQL injection vulnerability, one that executes arbitrary SQL commands but returns nothing, and use it to gain control of an account. <a href="https://www.youtube.com/watch?v=1sd26pWhfmg&amp;t=4s">Watch Nicholas Carlini</a> from Anthropic  describe this at the [un]prompted conference in San Francisco.

OpenBSD&#8212;which has a reputation as one of the most security-hardened operating systems in the world and is used to run firewalls and other critical infrastructure. The vulnerability allowed an attacker to remotely crash any machine running the operating system just by connecting to it;</p></blockquote><p>Project Glasswing is Anthropic&#8217;s stopgap solution to releasing a model so powerful that it can own any software anywhere. Only certain partners are allowed to play with it. </p><blockquote><p>Over the past few weeks, we have used Claude Mythos Preview to identify thousands of zero-day vulnerabilities</p></blockquote><p>Thousands. </p><p>Does anyone have the infrastructure to deal with thousands of new zero-days? Can the scanners keep up? Can the vulnerability enrichment solutions keep up? Imagine you are going to be patching every single app in your org each and every day. That is where this is going.</p><p>This feels like 2010. Virus signatures had exploded from a handful a week to 1,000 a day to 30,000 to 60,000 per day. The AV vendors were pushing signature updates six times a day. The model broke and the industry collapsed (<a href="https://www.amazon.com/Security-Yearbook-2025-Directory-Industry/dp/1394334869">read up</a> on the demise of Symantec and McAfee and the consolidation of AV vendors.) </p><p>We already know that bug research has been turned on its head by the use of AI. What happens when thousands of researchers use models like Mythos to discover new vulnerabilities? Do software companies (think Oracle, SAP, SFDC) even employ enough people to address all the disclosed vulnerabilities coming their way? Can they create and push patches fast enough?</p><p>Let&#8217;s say &#8220;over the past few weeks&#8221; means seven weeks and &#8220;thousands of zero-days&#8221; means 2,000. That is 285 new zero-days a week or roughly 15,000 a year. In 2025 there were 48,000 new CVEs cataloged. One team can now increase the total annual CVEs by 30%.  What happens when thousands of researchers are discovering thousands of zero-days every few weeks?  There are currently 360K CVEs. How can all of the systems scale to 3.6 million CVEs? </p><p>A whole bunch of things are going to break. Vulnerability Management writ large is going to break. </p><p>Anthropic has pushed ahead of the other AI labs for now. They are responsibly withholding Mythos Preview from general availability. But even the current models from all the labs are great at finding and exploiting vulnerabilities. The next models will be upon us shortly and its time to think about what this means for cybersecurity. </p><div><hr></div><p>If you want to dig into both sides of the reaction to Mythos Preview watch these two pundits. </p><p>First the <a href="https://x.com/theo/status/2041825324837781749">OMG this changes everything reaction</a>: </p><div class="captioned-image-container"><figure><a

Gartner, by its own admission only serves 12,000 or so customers out of a total addressable market of 140,000.  That&#8217;s less that 1%.  While we do have overlap with Gartner&#8217;s clients we also have an affordable alternative for the remaining 99.4%.  </p><p>IT-Harvest sells data on the entire cybersecurity industry.

All of the data and research posted here on Substack or Linkedin; all of my research, and yes, the six editions of <em>Security Yearbook</em> and now <em>Guardians</em>, was created to demonstrate the value of applied data for cybersecurity industry research. </p><p>Each post, each infographic, and each book is meant to spark the question: How can IT-Harvest produce this research and give it away for free? The whole point is that we can do that because it is easy and you could too if you were a Dashboard subscriber.</p><p>The other point is that we only expose a tiny fraction of the data we collect on 4,022 vendors and all of their products. Relying on my posts to get a picture of the cybersecurity industry is akin to owning just the Ser-Soosy volume of the Oxford English Dictionary.</p><div class="captioned-image-container"><figure><a

The investment was led by Ballistic Ventures, Merlin Ventures, and Norwest, with the company aiming to scale its operations and expand its market reach. Don&#8217;t forget that, while insiders pose a real and present danger, an outside attacker seeks to gain the same privileges as an insider.</p><p><strong>Adversa </strong>operates a red teaming platform designed for continuous adversarial testing of agentic AI systems, generative AI applications, and AI models. The platform simulates adversarial behavior in real time to discover exploitable vulnerabilities, including zero-day weaknesses in agent interactions, AI reasoning, coordination, and autonomy before they become breaches. The company provides capabilities for investigating, reproducing, and prioritizing remediation efforts for discovered AI vulnerabilities.</p><p><strong>Aether AI</strong> presents itself as an AI-driven offensive security platform that continuously tests an organization&#8217;s attack surface across internal and external vectors. The product is positioned as an alternative or complement to vulnerability scanners and traditional red-team engagements, with emphasis on automated, persistent testing. It cites performance claims including finding more vulnerabilities than human pentesters, faster execution than traditional red teams, lower cost than manual testing, and faster detection-rule generation than SOC analysts.</p><p><strong>AI Score</strong> is an enterprise AI governance and risk management platform focused on visibility, oversight, and control across an organization&#8217;s AI usage. The product connects data, tools, and teams to identify where AI is creating value, creating risk, or operating outside policy.</p><p>They aim to provide real-time risk detection, compliance monitoring, performance insight, and centralized governance rather than model development or deployment tooling. The company highlights enterprise deployment and security features including single-tenant architecture, broad integrations, SAML SSO, role-based access controls, and options for on-premise or private deployments.</p><p><strong>AISOC</strong> is an AI-assisted security operations platform that ingests and contextualizes SIEM alerts to help security and IT teams investigate incidents more efficiently. The company positions the product around alert triage, anomaly detection, case creation, and dashboard-based visibility into incidents, suppressions, notifications, and processing times. </p><div><hr></div><p>If I continue to post new vendors at the rate of five at a time I may never catch up.

Keep in mind that we are talking about the biggest technological shift in our lifetimes; bigger than the internet, mobile computing, virtualization, and cloud computing. So there are going to be outsize changes in the landscape.</p><p>-By the end of 2026, 95% of all SOCs will use AI agents including those of MSSPs.

post ruffled some feathers</a>. Chime in there if you have thoughts about my prediction. </p><p>When Security Yearbook 2025 went to press last January we tracked 80 vendors in the AI Security category. By April, I reported the number was 96.  When I sat down to write <em>Guardians</em> we were up to 295. To get to that number I had to go back to look at the 512 vendors founded in 2022-2025 and had to re-categorize many to AI Security. I only started tracking AI Security as a separate category in 2024. </p><p>When the manuscript for Guardians was complete two weeks ago there were 378 AI Security vendors. </p><p>Today we  track 407 AI Security Vendors. </p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

Eight have grown beyond the inclusion criteria.

That provided us with the list of 811 vendors including last year&#8217;s cyber 150 awardees. After removing those that had grown past 500 head count there were 767 vendors between 50 and 500 HC with positive growth last year. In the top 150, two had already been acquired.

The platform identifies risky user behaviors and delivers real-time, personalized interventions designed to change security-related actions and decisions. These interventions include AI-generated training content, nudges, two-way chats, workflows, and simulations delivered directly within employee workflows. Listen to my podcast with CEO Nicole Jiang-Gibson <a href="https://em360tech.com/podcasts/human-factor-cybersecurity-behavioural-interventions-work">here</a>. </p><p><strong>Noma Security</strong> provides unified AI and agent security and governance across enterprise AI environments, delivering visibility and control from model development through application runtime and autonomous agents. The platform performs continuous discovery of AI assets and agents within organizational environments, offering deep contextual understanding of agent profiles including toolsets, functionality, data access permissions, and operations.</p><p><strong>Adaptive Security</strong> only passed 50 people in November of 2024. Today it is at 187 and it grew 180%+ last year.  OpenAI invested in Adaptive in April.   It operates a platform designed to train people and organizations against threats most likely to target them. The company offers two primary products: Adaptive Phishing and Adaptive Training.</p><p><strong>VulnCheck</strong> raised an additional $25 million in February. It operates as an exploit intelligence provider focused on addressing vulnerability prioritization through automation-first delivery mechanisms. The company maintains a continuously updated database containing over 400 million records spanning all documented Common Vulnerabilities and Exposures, sourced from approximately 500 distinct channels. Their system automatically gathers vulnerability and exploit-related information at the moment of public disclosure, refreshing the entire dataset every eight hours without manual intervention requirements.  </p><p><strong>Formal</strong> operates as a protocol-aware reverse-proxy for datastores and APIs, enabling security teams to understand and control data access within their infrastructure. The platform deploys within customer VPCs as a single distroless Docker image, ensuring data never flows through Formal&#8217;s systems and remains under the organization&#8217;s complete control.</p><p><strong>Prophet Security</strong> develops an AI SOC Platform powered by an agentic AI SOC Analyst that autonomously triages and investigates security alerts. The platform performs alert triage by determining severity levels, prioritizing alerts based on importance, and providing remediation steps that integrate with existing workflows. It gathers evidence across security infrastructure and correlates data from multiple sources to build comprehensive investigation plans</p><p><strong>CleanStart</strong> provides a repository of secure, lightweight container images designed to help organizations build safer software supply chains. The images are minimal, hardened, and continuously verified to reduce risk and streamline deployment.</p><h2>How many were repeat winners? </h2><p>There were a handful of the 2025 Cyber 150 that graduated by exceeding 500 head count.

numerous such posts from those creating the AI revolution. There is a feeling  in the air that the Intelligence Explosion is nigh.</p><p>In other words, the scenario that I wrote about last April is happening right on schedule. In the <em>AI 2027</em> report it was projected that by 2026 AI would be used more and more to create the next LLMs. As Shumer notes that is exactly what happened in the creation of OpenAI&#8217;s latest model,  5.3 Codex.  </p><p>Shumer attempts to convey the rapid progression of AI models: </p><blockquote><p>In 2022, AI couldn&#8217;t do basic arithmetic reliably. It would confidently tell you that 7 &#215; 8 = 54.</p><p>By 2023, it could pass the bar exam.</p><p>By 2024, it could write working software and explain graduate-level science.</p><p>By late 2025, some of the best engineers in the world said they had handed over most of their coding work to AI.</p><p>On February 5th, 2026, new models arrived that made everything before them feel like a different era.</p></blockquote><p>Read Shumar&#8217;s thoughts before turning to the microcosm of  cybersecurity.  </p><p>When I wrote in April <em><a href="/__u/stiennon.substack.com/p/how-does-an-intelligence-explosion">How Does an Intelligence Explosion Impact the Future of Cybersecurity?</a> </em>the IT-Harvest Dashboard tracked 96 AI Security vendors with 15  of those focused on SOC Automation. </p><p>As I get ready to go to print on <em>Guardians of the Machine Age: Why AI Security Will Define the Future of Digital Defense</em>, we track 375 AI Security vendors. Almost all of them founded since 2022. </p><p>There are 58 companies tackling SOC Automation. They have received over $1.3 billion in funding. </p><p>2026 is the year that AI security will become part of every organization&#8217;s security tool kit. They may be small projects to begin with but as they begin having an impact on security outcomes AI Security solutions will take over our industry. By this time next year there will be no sense to tracking &#8220;AI Security&#8221; as a stand-alone category. Every vendor will be AI Security. </p>]]></content:encoded></item><item><title><![CDATA[Momentum Cyber's Almanac]]></title><description><![CDATA[After a four year hiatus Momentum Cyber, the

January.</a> Let&#8217;s check in to see how they did. The purpose of pulling together this list was to demonstrate the value of a data-centric approach to studying the cyber security industry. We simply take a look at all the vendors in the size range of 50-500 people. Then we sort them by growth and take the top 150. If you were an investor or PE firm this would be a great place to start. </p><p>After a complete year:</p><p>These seven have graduated  out of consideration for the 2026 award because they exceeded 500 people. </p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"
