Israeli startup Zenity bags $125M in funding to build the security layer for AI agents

Israeli AI security startup Zenity has successfully closed a $125 million Series C funding round to bolster its platform designed to secure autonomous AI agents in production for large global organizations. Led by Norwest, the investment was made alongside SoftBank Vision Fund 2, Qumra Capital, Hitachi Ventures, LG Technology Ventures, Vertex Ventures, DTCP, and Intel Capital. Zenity's funding total now stands at $185 million.

The startup aims to tackle a growing security concern as enterprises increasingly shift from experimental AI agent deployments to scaling them in production. Most existing AI security solutions focus on protecting AI models or the prompt layer, but autonomous AI agents present unique challenges. These agents must access various enterprise systems, invoke third-party software tools, make decisions, and execute business processes, creating a sprawling attack surface that current identity, application, and data security tools cannot effectively cover.

Zenity's platform analyzes business computing environments to identify AI agent integration points and interactions with different systems. It determines each AI agent's intended business purpose and monitors them in real time to ensure they adhere to organizational policies and permissions. By proactively studying the intent behind each action, Zenity helps security teams approve, modify, or block agent actions dynamically, distinguishing legitimate business activity from attempts to manipulate or misuse AI agents.

The platform supports popular AI environments like Google Gemini, OpenAI ChatGPT Enterprise, Microsoft Copilot, Anthropic Claude, and internally developed agents. Proven successful with Fortune 500 and Global 2000 customers across healthcare, financial services, pharmaceuticals, manufacturing, and technology, Zenity's Series C funding will enhance its agentic security platform, expand operations, and strengthen its security research arm, Zenity Labs, which regularly uncovers high-profile vulnerabilities in AI systems.
