AI security platform Zenity has raised $125 million in a Series C funding round to accelerate the protection of artificial intelligence agents operating across large enterprise organizations worldwide. The Boston and Tel Aviv-based company announced the investment, which brings its total capital raised to approximately $185 million since its founding in 2021.
The round was led by Norwest Venture Partners alongside Qumra Capital and SoftBank Vision Fund 2. Additional participants included Hitachi Ventures, LG Technology Ventures, Vertex Ventures, Third Point Ventures, DTCP, and Intel Capital. The funding will support platform expansion, global growth, and the continued development of Zenity Labs, the company’s research division.
Zenity was founded by serial security entrepreneurs Ben Kliger and Michael Bargury to build software that manages the security of AI agents. The company now employs over 230 professionals worldwide, with development centered in Tel Aviv and commercial operations overseen from New York. New office space at One Embarcadero will facilitate scaling across key markets in EMEA, Europe, and APAC.
Enterprise demand for AI agent governance has surged as organizations deploy autonomous systems in sensitive domains. Zenity’s customer base includes Fortune 500 and Global 2000 companies across Fintech, biotech, pharmaceuticals, energy, and industrial sectors. The company reports nearly tripling its revenue for two consecutive years as enterprise AI adoption accelerates.
Zenity’s platform analyzes the intent of AI agents prior to execution, enabling real-time decisions to approve, reject, or modify actions. The technology supports agents built on major enterprise platforms including Microsoft Copilot, ChatGPT Enterprise, Google Gemini, Microsoft Foundry, Google Vertex AI, Claude, Codex, and Cursor. This broad compatibility allows organizations to apply consistent governance across diverse AI environments.
Beyond its commercial offering, Zenity Labs has established a reputation for cybersecurity research. The team has disclosed several high-profile vulnerabilities affecting enterprise AI systems, including AgentFlayer, a new class of zero-click attacks capable of compromising AI agents without user interaction. Researchers have also uncovered flaws in Microsoft Copilot Studio, Perplexity’s Comet browser, and connected enterprise services that could expose sensitive data. Findings have contributed to industry frameworks such as the OWASP Top 10 and MITRE ATLAS.
Industry recognition has reinforced Zenity’s position. Earlier this year, Gartner identified the company as a leading vendor in AI agent governance, citing its purpose-built architecture and intent-aware security capabilities.
As organizations increasingly rely on AI agents to automate critical operations, demand for specialized governance platforms is expected to grow. The latest funding provides resources to expand globally while advancing security technologies that help enterprises deploy AI agents safely and at scale.
