Zenity has closed a $125M Series C led by Norwest to scale its security platform for autonomous AI agents. Qumra Capital, SoftBank Vision Fund 2, Hitachi Ventures and LG Technology Ventures are new investors, while Vertex Ventures, Third Point Ventures, DTCP and Intel Capital increased their stakes.
The company’s pitch: as agents gain the power to read email, query databases, run code and trigger applications, enterprises need a control layer that understands intent. Zenity’s platform sits between agents and the systems they touch, deciding in real time whether to allow, modify or block an action before it happens.
CEO Ben Kliger argues the market is entering an era of one billion agents, with adoption spreading through SaaS tools, coding assistants and cloud infrastructure. Zenity Labs has shown how vulnerable that shift can be, disclosing AgentFlayer, a class of zero-click exploits that hijack enterprise agents, plus flaws affecting Microsoft Copilot Studio and ChatGPT-linked services.
The company counts Fortune 500 and Global 2000 customers across financial services, healthcare and technology, including SoftBank. Revenue has tripled in each of the past two years and is tracking another triple this year, with more than 230 employees split between Tel Aviv R&D and New York go-to-market.
Fresh capital will fund platform development, expand Zenity Labs and push into Europe and Asia Pacific. The round is a bet that securing agent actions becomes one of the defining cybersecurity problems of the agentic AI era.
