Zenity
Security and governance platform purpose-built for AI agents, from discovery to inline prevention.
About
Zenity is a Tel Aviv and New York based AI security company founded in 2021 that positions itself as the first security and governance platform built expressly for AI agents. Its platform covers the agent lifecycle end to end: continuous discovery of agents and their posture, real-time detection of manipulated or rogue behavior, inline prevention that can allow, modify, or block agent actions, and response. The agent-centric model watches what agents are trying to do, what data they access, and which tools they invoke, rather than relying on soft boundaries like prompt filtering.
Coverage spans SaaS-managed agent platforms such as Microsoft 365 Copilot, ChatGPT Enterprise, and Salesforce Agentforce, custom agent stacks on AWS Bedrock, AgentCore, Google Vertex AI, and Foundry, plus developer tools like GitHub Copilot and Cursor running on endpoints. Zenity Labs, the company's research arm, hunts vulnerabilities in agentic platforms and disclosed AgentFlayer in August 2025, a family of zero-click exploit chains against enterprise agent platforms. The company raised a $125M Series C in August 2026 led by Norwest, bringing total funding to $180M, employs over 230 people, and was named a 2025 Gartner Cool Vendor in Agentic AI Trust, Risk and Security Management. Its customers include Fortune 500 enterprises.
What it can do
- Continuous agent discovery and posture management across SaaS, cloud, and endpoint

- Zenity Labs vulnerability research and responsible disclosure
- Full-lifecycle governance from build-time assessment to runtime enforcement
Setup
- Engage Zenity for an enterprise deployment via zenity.io.
- Connect SaaS agent platforms (Copilot, ChatGPT Enterprise, Agentforce) and cloud agent stacks (Bedrock, Vertex AI, Foundry) for discovery.
- Define policies for what agents may access and which tool actions are permitted.
- Turn on real-time detection and inline prevention, and route findings into your SOC workflow.
Prerequisites
Enterprise contract with Zenity; admin access to the agent platforms and cloud environments being secured.
Use cases
Works with
Trust score — 7/10
Scored 7/10 (verified tier, metrics-v1). Evidence: $125M Series C led by Norwest announced Aug 2026, $180M total (Security Week); 230+ employees, Tel Aviv R&D and New York GTM; 2025 Gartner Cool Vendor in Agentic AI TRiSM; AgentFlayer zero-click research disclosed Aug 2025; zenity.io verified live. Strengths: deep funding, Fortune 500 customer base, public research output, hard-boundary enforcement model. Docked for: (1) proprietary enterprise SaaS, no public pricing; (2) 'first platform' positioning is vendor marketing; competing agent-security vendors make similar claims. License: proprietary.
