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

Artificial intelligence security startup Zenity Ltd. said today it has closed on a $125 million Series C round of funding to expand its platform, which secures autonomous agents in production across large global organizations.

Today’s round was led by Norwest and saw participation from SoftBank Vision Fund 2, Qumra Capital and others, including Hitachi Ventures, LG Technology Ventures, Vertex Ventures, DTCP and Intel Capital. It means Zenity has now raised $185 million in total funding to date.

The startup now has a massive war chest available to it as it looks to tackle a security problem that’s becoming much more urgent as enterprises shift away from experimental AI agent deployments to scale them in production.

To date, most AI security offerings have focused on protecting the underlying AI models or the prompt layer, trying to prevent them from being manipulated by malicious users. But autonomous AI agents designed to perform real business work on behalf of humans present entirely different security challenges. To perform their work, AI agents need to be able to access all kinds of enterprise systems, invoke third-party software tools, make decisions and execute business processes. They create an entirely new and sprawling attack surface, which cannot easily be covered using existing identity, application and data security tools designed for human users.
