Zenity, the AI security and governance platform purpose-built for AI agents, has announced a $125 million Series C led by Norwest. The investment will accelerate Zenity's global expansion, platform innovation, and ability to meet rapidly growing enterprise demand for AI agent security. Trusted by some of the world's largest enterprises, Zenity has spent years helping organizations securely adopt AI while the rest of the industry was still focused primarily on protecting models and individual prompts. New investors Qumra Capital, SoftBank Vision Fund 2, Hitachi Ventures, and LG Technology Ventures joined the round, alongside existing investors Vertex Ventures, Third Point Ventures, DTCP, and Intel Capital.
Zenity raised $125 million in Series C funding led by Norwest, with participation from Qumra Capital, SoftBank Vision Fund 2, Hitachi Ventures, and LG Technology Ventures.
The company is trusted by Fortune 500 and Global 2000 enterprises across financial services, healthcare, technology, energy, and manufacturing.
Zenity has tripled revenue in each of the past two years and is on track to triple revenue again this year.
The platform provides deterministic security for AI agents by understanding intent and blocking actions before they occur, covering Microsoft Copilot, ChatGPT Enterprise, coding agents, and custom agentic systems.
Gartner recognized Zenity as the company to beat in AI agent governance, citing its purpose-built agentic-centric architecture and intent-aware detection.
Zenity Labs has uncovered critical vulnerabilities including zero-click attacks capable of hijacking enterprise AI agents and exfiltrating sensitive data.
Enterprise AI security has historically focused on the model layer or on trying to secure only the prompt layer. Today's challenge is fundamentally different. AI agents can access critical systems and data, invoke tools, make decisions, and take action, requiring a security approach built for increasingly autonomous agents. Zenity's platform has evolved alongside the agents it protects. Rather than relying solely on prompt inspection or post-incident analysis, Zenity deterministically allows, modifies, or blocks an action before it occurs by understanding an agent's intent and distinguishing legitimate work from behavior that has been manipulated, compromised, or falls outside its intended purpose.
Zenity is trusted by many of the world's largest enterprises, with the majority of its customers comprising Fortune 500, Global 2000, and other leading global organizations, including SoftBank Corp. Across financial services, healthcare, pharmaceuticals, technology, energy, manufacturing, and other highly regulated industries, these organizations rely on Zenity to securely govern and scale AI agents. Its longest-standing customers include many Fortune 50 companies. Zenity has tripled revenue in each of the past two years and is on track to triple revenue again this year.
Earlier this year, Gartner recognized Zenity in the report, AI Vendor Race: Zenity Is the Company to Beat in AI Agent Governance, published in April 2026. According to the research, "Zenity's purpose-built agentic-centric architecture, intent-aware detection and continued end-user interest put it at the forefront of the AI agent governance race." The report also states that "enterprise adoption of autonomous AI systems is rapidly amplifying risks and invigorating activity in the AI agent governance market." Zenity uniquely contributes to the security community through well-informed security research, contributions to OWASP Top 10 frameworks, and open-source frameworks like MITRE ATLAS, highlighting the company's role in shaping the standards and research that underpin the emerging market.
"Zenity has an early mover advantage in building an end-to-end AI agent security and the largest and rapidly growing footprint of successful implementation across Fortune 1000 customers," said Assaf Harel, Partner at Norwest. "The company is in pole position to emerge as a category leader, and we're excited to partner with Ben, Michael and the entire team as they continue to shape the future of AI agent security."
"As our use of AI agents continues to grow, maintaining security, governance and operational control is essential," said Tadashi Iida, Senior Vice President & CISO & CRO, SoftBank Corp. "Zenity enables us to confidently deploy AI agents across the enterprise, giving us the visibility and governance required to support innovation at scale."
"Enterprise AI is skyrocketing," said Ben Kliger, co-founder and CEO of Zenity. "AI experimentation is long over and any organization on the planet is promoting AI agents at velocity and adoption rates never seen before in any tech wave. AI agents change everything in the way that we all work and operate as enterprises are promoting agentic AI in SaaS, on local devices with coding agents and agentic browsers and in their public cloud infrastructure. They are rebuilding their infrastructure with agentic infrastructure and employees that access enterprise data, tools, and own business processes and decisions. Michael and I founded Zenity on the belief that software development has changed and is not only reserved for highly skilled engineers, and that it requires an entirely new approach to cybersecurity. As we enter the era of 1 billion agents, our newly announced funding is helping make that vision a reality. This investment allows us to bring AI agent security to many more organizations around the world."
Zenity's leadership extends beyond its platform. Through Zenity Labs, the company's research team has repeatedly uncovered industry-defining vulnerabilities in agentic AI frameworks that have influenced how enterprises and technology providers understand and defend autonomous AI. Its groundbreaking AgentFlayer exposed a new class of zero-click attacks capable of silently hijacking enterprise AI agents to manipulate workflows, exfiltrate sensitive data, and abuse connected systems without user interaction. The team's research has also demonstrated how a single malicious calendar invitation could hijack Perplexity's Comet browser and access an unlocked 1Password vault, uncovered a critical vulnerability in Microsoft Copilot Studio, and showed how a poisoned document uploaded to ChatGPT could abuse connected services such as Google Drive and SharePoint to exfiltrate sensitive enterprise data.
Zenity now has more than 230 employees worldwide, with its research and development center in Tel Aviv and go-to-market and operations led from New York, serving customers and partners across the globe. The investment will accelerate platform innovation, expand Zenity Labs, deepen the company's existing global presence particularly across Europe and Asia Pacific, and help define the security standards enterprises rely on as AI agents become foundational to modern business.
