Zenity Raises $125M for AI Agent Security Platform

In a significant development for enterprise AI adoption, Israeli cybersecurity innovator Zenity has successfully closed a $125 million Series C funding round. This substantial capital infusion, led by Norwest with significant backing from SoftBank Vision Fund 2, Qumra Capital, Hitachi Ventures, LG Technology Ventures, Vertex Ventures, DTCP, and Intel Capital, propels Zenity's total funding to $185 million. The company is poised to accelerate the development and deployment of its pioneering security platform designed specifically for autonomous AI agents operating within complex business environments.

The escalating use of AI agents, which are increasingly tasked with executing critical business functions, presents a novel and complex security challenge. Unlike traditional AI security that often focuses on model integrity or prompt manipulation, Zenity addresses the unique risks posed by agents that interact with enterprise systems, invoke third-party tools, and make autonomous decisions. These agents create an expanded attack surface that existing security frameworks, built for human users, struggle to adequately protect. Zenity's platform aims to bridge this critical gap, enabling organizations to scale AI initiatives with confidence.

Zenity's core technology provides a robust security layer by deeply analyzing the operational context of AI agents. The platform maps agent integrations, understands their intended business purposes, and meticulously monitors their real-time actions against predefined organizational policies and permissions. This proactive approach moves beyond reactive threat detection, focusing instead on understanding the intent behind agent operations before execution. This allows security teams to dynamically approve, modify, or block agent activities, ensuring alignment with governance requirements.

The company's innovative approach is already gaining traction among major enterprises. Zenity reports significant adoption across Fortune 500 and Global 2000 companies in sectors including healthcare, financial services, pharmaceuticals, manufacturing, and technology. SoftBank Group Corp., a key investor in this round, also highlighted Zenity's value. Tdashi Iida, Senior Vice President and CISO at SoftBank Group Corp., stated, "Zenity enables us to confidently deploy AI agents across the enterprise, giving us the visibility and governance required to support innovation at scale." This endorsement underscores the growing demand for specialized AI agent security solutions.

Further bolstering its market position, Zenity's dedicated research arm, Zenity Labs, has actively identified and disclosed significant vulnerabilities in prominent AI systems, including those from Microsoft and Perplexity AI. This research not only highlights the critical need for advanced AI security but also directly informs and enhances Zenity's product development. The insights gained from uncovering uncontrolled agent behavior are continuously integrated into the platform, ensuring it remains at the forefront of AI threat mitigation.

With this new funding, Zenity plans to significantly scale its commercial operations, expanding its reach into key international markets such as Europe, Asia-Pacific, and the Middle East. The investment will also fuel further enhancements to its agentic security platform and bolster the capabilities of Zenity Labs. As the deployment of autonomous AI agents accelerates globally, Zenity is positioning itself as an essential partner for organizations navigating the complexities of securing these powerful new tools.
