Neo Security

Real-time AI agent governance across endpoints

Overview

Neo Security provides a real-time governance layer that inventories and controls AI agents and agentic software across enterprise endpoints, browsers, SaaS, and developer tools. Its platform continuously discovers agents, attributes their actions, and enforces policies before risky behavior can execute, while maintaining an audit trail for SecOps visibility. This cross-environment approach, created by veterans from SentinelOne, Wiz, and Palo Alto Networks, differentiates Neo from others by combining broad coverage with strict policy enforcement and action logging. The goal is to let organizations deploy AI agents securely, preserving governance and control without slowing down AI adoption.

Simplify's take

What believers are saying

  • Neo launched Claude Cowork VM visibility on November 2, 2026, expanding runtime coverage.
  • Neo’s October 29 tamper protection hardens enforcement, improving stickiness and customer trust.
  • Scott Stout joined as CRO on October 26, 2026, accelerating enterprise pipeline and channels.

What critics are saying

  • Crowded incumbents like CrowdStrike, Microsoft, and Palo Alto can bundle agent controls into suites.
  • Neo’s October 2026 tamper protection only secures Neo hooks, leaving broader policy bypass paths.
  • If enterprise agent adoption stalls after 2027, Neo’s category thesis loses urgency and budget priority.

What makes Neo Security unique

  • Neo’s on-device sensor sees agent actions inside endpoints, browsers, and Claude Cowork VMs.
  • Neo maps every action to device, user, and session, strengthening auditability for SecOps.
  • Former SentinelOne, Wiz, and Palo Alto veterans anchor Neo’s credibility with enterprise buyers.

Neo extends AI security into Claude Cowork virtual machines for full runtime visibility

Neo, an AI security platform, has launched an integration that extends its monitoring into the isolated virtual machines (VMs) where Claude Cowork runs. The company announced the move on November 2, 2026. Cowork runs its most sensitive actions inside VMs, and most security tools cannot see what happens within them, such as which files an agent opens or which hosts it contacts. Neo's sensor monitors that activity and maps each action to the device, user, and session it came from. Neo combines this with its Neoverse software intelligence engine and endpoint telemetry to show which agents are running and what risk they carry. The integration will be available to all Neo customers. "Security teams can't govern AI they can't see," said Shlomi Salem, the company's chief product officer and co-founder.

Neo brings security visibility inside Claude Cowork. BOSTON, Nov. 02, 2026 (GLOBE NEWSWIRE) - Neo, the AI security control platform, today announced a new integration for Claude Cowork that extends Neo into the isolated virtual machines where Cowork runs. Neo identifies the semantic intent behind every Cowork action wherever it occurs and provides runtime visibility with agentic security intelligence, delivering a complete understanding of exactly what each agent is doing, what it is interacting with, and what risk that represents for the environment. Claude Cowork is popular for taking multi-step instructions and returning finished work. To keep this work isolated, Cowork runs its most sensitive actions inside VMs. Most security tools can see the VM but not what happens inside it: which file the agent opens, what processes it starts, or which hosts it contacts. As adoption grows, more agentic activity happens in a black box that security teams cannot monitor at runtime or investigate after the fact. "Security teams can't govern AI they can't see," said Shlomi Salem, Chief Product Officer and Co-founder of Neo. "Growing Cowork adoption shouldn't mean more visibility gaps. Isolation is good design for sensitive work, but security teams still need to know what an agent is doing, wherever it runs. The Neo sensor monitors activity inside the Cowork VM and understands the risks of the other AI components around it, delivering teams the context they need to make decisions." Existing security tools offer only a partial view of Cowork actions. Traditional EDR tools with access to the VM can monitor activity for signs of attack, but lack the necessary AI security intelligence to understand what risk each Cowork agent represents to each environment. Seeing what an agent is doing in a VM without knowing who it is doing it for or understanding the other agentic components it is interacting with delivers an incomplete view of agentic risk. Neo combines real-time visibility into Cowork VMs with Neoverse, its software intelligence engine and broader endpoint telemetry, so customers can understand the agents they run and the risk they carry. Every Cowork action is mapped back to the device, user, and session from which it originated, giving security teams the trails they need to conduct investigations. The result is a current view of which agents are running, what they interact with and what that means for the enterprise, so teams can investigate faster. Neo for Claude Cowork will be available for all Neo customers. For more information on Neo and Cowork, read our blog and register for the November 30th webinar here.

The Neo platform gives security teams the inventory, intelligence, attribution, and policy control required to govern agentic software across AI agents, AI-enabled applications, browsers, identities, and traditional software as enterprise applications become autonomous. Founded by SentinelOne veterans and backed by Andreessen Horowitz, Bessemer Venture Partners, Craft Ventures, and Merlin Ventures, Neo enables organizations to adopt AI securely while maintaining the visibility and control required to manage risk across the enterprise.

Neo launches tamper protection to stop users and AI agents disabling security policies

Neo, an agentic software control company, has launched Tamper Protection for AI Agents. The feature keeps its security policies in force when a user or an AI agent tries to disable, remove, or bypass them. The first protection stops anyone from deleting or altering the hooks Neo installs in Claude Code, Claude Cowork, Codex, Cursor, and Copilot. Hooks let security tools see what an agent is about to do and decide whether it happens. Hooks installed only through setup scripts or periodic mobile device management updates can stay disabled until the next update. Neo's sensor stays on the device, recording a fingerprint of each hook and blocking any change. It covers only Neo's own hooks and runs in the existing sensor, so customers deploy nothing new. "A security policy can't be optional for the person or agent it governs," said chief executive officer Nick Warner.

Neo named to 2027 Fortune Cyber 60 for innovation in AI security.

Neo named to 2027 Fortune Cyber 60 for innovation in AI security. Company recognized for helping enterprises prevent AI threats across devices, browsers, identities and applications. BOSTON, Oct. 28, 2026 (GLOBE NEWSWIRE) - Neo, the Agentic Software Control company, today announced it has been named to the 2027 Fortune Cyber 60. Presented by Lightspeed Venture Partners and Amazon Web Services (AWS) in partnership with Fortune, the list recognizes the most important venture-backed cybersecurity companies driving innovation within the industry. Cyber 60 honorees are selected following extensive proprietary research, industry validation and market analysis by Lightspeed and Fortune. Hundreds of companies were evaluated based on annual recurring revenue, current and prior-year growth and business operations. "Fortune and Lightspeed have a proven track record of identifying the companies combating the most critical cybersecurity issues in the Fortune Cyber 60," said Nick Warner, CEO and Co-founder of Neo. "AI agents reason, invoke skills, and act with real user permissions, breaking the assumption that software behaves predictably. Neo understands the semantic intent behind every agent action and gives security teams runtime control wherever agents operate: devices, browsers, identities, and apps." A recent Lightspeed Cyber60 Survey of hundreds of CISOs finds that enterprise AI adoption is advancing faster than the controls needed to secure it. This industry trend is shaping market direction - agent identity, authorization, and access governance is the leading category CISOs plan to evaluate over the next year. While AI agents are in production at 77% of surveyed companies, only 20% report having a complete agent inventory and confidence in their teams' ability to assess and mitigate AI-specific risks has fallen from 71% last year to just 55% in 2026. Neo exists to confront these issues. The absence of agentic oversight and lack of confidence regarding agentic security is a direct result of high-speed, haphazard AI adoption. Software vendors are shipping new agentic capabilities for widely used tools, while users install new agentic applications without security reviews. To manage this mutating threat surface, SecOps teams need a living inventory of the AI agents and applications they use, real-time visibility into human and non-human activity and an understanding of what those tools can do, a verdict on whether or not they are a fit for their environment, and the ability to enforce policies based upon that verdict. With Neo, security teams can discover and inventory the suite of tools running across the enterprise even as they add new agentic functions, understand their changing capabilities and risks, assess whether they are configured safely, and enforce policy before risky activity occurs wherever it occurs. Real-time visibility into both human and non-human activity, attribution that maps actions back to the responsible user or agent, and granular policy enforcement across devices, browsers, identities, and traditional applications deliver the agentic control organizations need to effectively manage agentic transformation at scale. About Neo Neo is the Agentic Software Control company built for modern AI-driven enterprises. The Neo platform gives security teams the inventory, intelligence, attribution, and policy control required to govern agentic software across AI agents, AI-enabled applications, browsers, identities, and traditional software as enterprise applications become autonomous. Founded by SentinelOne veterans and backed by Andreessen Horowitz, Bessemer Venture Partners, Craft Ventures, and Merlin Ventures, Neo enables organizations to adopt AI securely while maintaining the visibility and control required to manage risk across the enterprise.
