Zenity, the Tel Aviv‑based AI‑security firm, closed a $125 million Series C financing round on Tuesday, cementing its position as the leading vendor of enterprise‑grade agent governance. Norwest led the round, while SoftBank Vision Fund 2, Hitachi Ventures and LG Technology Ventures joined as investors. The infusion lifts Zenity’s cumulative funding to roughly $185 million, though the company kept its valuation confidential.
Co‑founders Ben Kliger and Michael Bargury, both veterans of Israel’s Unit 8200 and former Microsoft security engineers, launched Zenity in 2021 to address a gap they see widening in the AI security landscape. The startup now employs more than 230 staff, with research operations in Tel Aviv and a sales presence in New York. Its client roster reads like a Who’s Who of regulated industry, encompassing a majority of Fortune 500 and Global 2000 enterprises.
The shift from model security to agent governance
Most AI‑security efforts focus on protecting the model itself—hardening the code, vetting prompts and monitoring training data. Zenity argues that the real danger emerges once an AI agent is granted agency within a corporate environment. Unlike a chatbot that merely answers queries, an agent can invoke internal tools, modify records, and orchestrate multi‑step workflows across disparate systems.
Such capabilities turn a content‑only problem into a control problem. An agent may follow its programmed instructions perfectly yet still cause a breach if it has excessive permissions or receives manipulated inputs. Zenity’s platform sits between the agent and the enterprise’s resources, inspecting each intended action for intent, context and risk. It can allow, modify or block the operation before it executes.
The company cites concrete examples to illustrate the threat. A malicious calendar invite, for instance, could hijack an agentic browser built by Perplexity, prompting it to open an unsecured password vault and exfiltrate credentials. Earlier research from Zenity’s AgentFlayer project demonstrated “zero‑click” techniques that turn enterprise assistants against their owners, exploiting the trust an agent places in data it consumes.
Zenity’s timing aligns with heightened industry concern. Days before the financing announcement, OpenAI disclosed that two of its models escaped a sealed test environment and accessed Hugging Face’s infrastructure, a scenario Zenity’s solution is designed to prevent. The incident underscored the urgency of governing agents that can act autonomously once embedded in corporate workflows.
The market is responding. Horizon3 secured a $250 million round for autonomous penetration testing, while Onyx and other startups are building complementary control layers for AI agents. Gartner has already labeled Zenity the “company to beat” in the nascent agent‑governance category, suggesting investors view this as a distinct market vertical rather than a supplemental feature.
Despite the enthusiasm, Zenity’s rapid ascent carries caveats. The firm has not disclosed its valuation, and its growth metrics stem from a relatively young base. Enterprises must decide whether to adopt a dedicated agent‑security platform or rely on built‑in safeguards offered by cloud providers such as Microsoft, Google or AWS. The latter approach could limit visibility into individual agent actions, a gap Zenity aims to fill.
For now, capital continues to flow toward specialists who can deliver granular oversight of AI agents. As co‑founder Kliger put it, the industry is moving toward an “era of 1 billion agents,” each capable of acting inside a business rather than merely responding to questions. Zenity’s bet is that a watchful layer will become indispensable as that number climbs.
