Zenity, a security platform for artificial intelligence agents, has closed a $125 million Series C funding round led by Norwest. This investment is earmarked for accelerating the company's global expansion and advancing its platform innovations. The funding arrives as enterprises increasingly deploy autonomous AI, creating an urgent need for specialized security to manage this new technological wave.
Addressing a New Frontier in AI Security
The rapid enterprise adoption of AI agents has introduced security challenges that traditional methods cannot address. While older security models focused on protecting AI models or prompts, today's autonomous agents can access critical data and execute actions independently. Zenity developed its platform specifically to govern these complex, high-risk interactions and secure this evolving reality.
Zenity's platform operates by understanding an agent's intent, allowing it to preemptively permit, alter, or block an action before it occurs. This proactive approach provides a unified security layer across diverse agentic frameworks from Microsoft, Google, and OpenAI. It distinguishes legitimate tasks from behavior that has been compromised or falls outside an agent's intended purpose.
Strong Market Traction and Investor Confidence
The company has demonstrated impressive growth, tripling its revenue in each of the last two years with projections to repeat this success. Its customer base includes many Fortune 500 organizations across highly regulated industries like finance and healthcare. Customer SoftBank Corp.'s CISO noted that Zenity enables the confident deployment of AI agents at scale.
The Series C round saw participation from new investors like SoftBank Vision Fund 2 and Hitachi Ventures, alongside existing backers. Assaf Harel, a partner at lead investor Norwest, praised Zenity's vision and early mover advantage. He stated the company is positioned to become a category leader in AI agent security.
Pioneering Research and Industry Leadership
Beyond its commercial platform, Zenity contributes to the security community through its research arm, Zenity Labs. The team has uncovered industry-defining vulnerabilities, including a new class of zero-click attacks dubbed "AgentFlayer" that can hijack enterprise AI agents. This research helps shape how organizations and providers understand and defend against emerging autonomous AI threats.
The company's leadership is further validated by its contributions to open-source security frameworks like OWASP and MITRE ATLAS. A recent Gartner report recognized Zenity as "the company to beat in AI agent governance," highlighting its purpose-built architecture. This external recognition underscores the company's pivotal role in defining standards for a rapidly growing market.
Future Plans and Global Expansion
With over 230 employees, Zenity plans to use the new capital to fuel platform innovation and expand its research capabilities. The investment will also deepen its global presence, with a focus on growing operations across Europe and the Asia Pacific region. This strategic expansion aims to meet the surging international demand for robust AI governance solutions.
Co-founder and CEO Ben Kliger emphasized that AI experimentation is over, with enterprises now adopting agents at an unprecedented rate. He stated this shift requires a new cybersecurity approach as the world enters an "era of 1 billion agents." The funding will help Zenity realize its vision of making this new technological landscape secure.
This $125 million investment is a powerful endorsement of Zenity's specialized approach to securing the next wave of enterprise AI. The funding validates the critical need for security solutions tailored to autonomous agents and provides resources for expansion. As businesses integrate AI into core operations, Zenity is positioned to ensure this transformation is both innovative and secure.
