Zenity Secures $125 Million Series C to Bolster AI Agent Security and Governance
AI security platform Zenity has raised $125 million in Series C funding to enhance the security and governance of autonomous AI agents, addressing growing enterprise concerns over data access and workflow execution.
AI security and governance platform Zenity announced a significant $125 million Series C funding round, led by Norwest, signaling a heightened enterprise focus on the security risks posed by autonomous AI agents. The investment round saw participation from new strategic backers including Qumra Capital, SoftBank Vision Fund 2, Hitachi Ventures, and LG Technology Ventures, alongside re-investment from existing partners like Vertex Ventures and Intel Capital.
Unlike traditional AI security solutions that concentrate on model protection or input filtering, Zenity's platform is designed to monitor and control the runtime actions of AI agents operating within enterprise environments. These agents are increasingly integrated into various SaaS platforms, cloud infrastructure, developer workflows, and business tools, granting them access to critical resources such as internal email, cloud storage, CRM data, and source code repositories.
This deep integration, while driving efficiency, creates novel attack surfaces. A compromised or manipulated AI agent could inadvertently leak confidential data, initiate unauthorized financial transactions, or misuse connected tools. Zenity's approach aims to establish deterministic governance over these inherently non-deterministic agentic systems, moving AI defense from reactive log analysis to proactive threat prevention.
The Zenity platform offers real-time visibility and preventive guardrails for agentic environments. It analyzes an agent's intended actions before execution, allowing, modifying, or blocking requests to ensure alignment with organizational policies. This capability extends to both commercial off-the-shelf agents and custom-built agentic frameworks, helping organizations mitigate risks like prompt injection and unauthorized agency across diverse AI deployments.
Zenity Labs, the company's dedicated threat research arm, actively contributes to industry standards and frameworks such as OWASP and MITRE ATLAS. Their research has highlighted critical attack vectors, including zero-click exploits that allow threat actors to hijack enterprise AI agents for multi-step workflow manipulation and data exfiltration without direct user interaction. Indirect prompt injection techniques, leveraging malicious calendar invites or poisoned documents, are also a focus.
The company reports significant growth, having tripled its annual recurring revenue for the past two years, and serves major enterprises across finance, healthcare, manufacturing, and technology sectors, including Fortune 500 and Global 2000 leaders. The newly acquired capital will fuel expansion into Europe and Asia-Pacific, scale Zenity Labs' research operations, and enhance preventive security controls for enterprise AI deployments.
Zenity's platform supports a wide array of AI frameworks and ecosystems, including Microsoft Copilot, Google Gemini, AWS Bedrock, and custom agent frameworks. By providing specialized security platforms, Zenity empowers security teams to proactively test and harden the complex execution paths of AI agents, ensuring that the benefits of AI automation do not come at the cost of critical security vulnerabilities.
