Zenity, a company focused on AI security and governance, announced a $125 million Series C funding round. The capital increase brings the total amount raised by the firm to $180 million, and it is designed to accelerate product development, expand Zenity Labs, and strengthen the company’s global go-to-market reach.
The round was led by Norwest. Additional participation came from Qumra Capital, SoftBank Vision Fund 2, Hitachi Ventures, LG Technology Ventures, and earlier backers including Vertex Ventures, Third Point Ventures, DTCP, and Intel Capital.
Since its founding in 2021, Zenity has been working on a practical approach to helping organizations adopt AI safely—especially as “agentic” systems begin to take actions on behalf of users. Instead of treating security as an afterthought, the platform aims to understand what an agent is trying to do and then allow, modify, or block actions in a deterministic way.
Why AI agent security is becoming a priority
As enterprises move from chat-based experiences to AI agents that can execute tasks, the risk model shifts. It’s no longer only about whether an application can generate the right text—it’s also about whether it might perform harmful actions, follow the wrong instructions, or behave unexpectedly.
Zenity positions its technology as a layer that can separate legitimate work from manipulated, compromised, or rogue behavior. The goal is to reduce the chance that malicious agent activity can affect business systems before it causes damage.
In other words, the company is aiming to enable safer operations at the moment decisions are made—when an AI agent is about to act—rather than attempting to detect problems later.
How Zenity’s platform supports secure adoption
Zenity describes its platform as a unified security layer that covers a wide range of agentic AI frameworks. The company highlights support for major enterprise AI environments such as Copilot, ChatGPT Enterprise, Gemini, Claude Codex, and Cursor.
Beyond those, Zenity also references coverage for custom-built systems running on Bedrock, AgentCore, Foundry, and Vertex AI. This matters because enterprises often combine vendor services with internal implementations, and security controls must adapt to that mix.
Instead of forcing organizations to redesign their agent stack, Zenity’s approach is centered on consistently evaluating agent intent and determining what actions should be permitted. By combining understanding with deterministic enforcement, the platform is intended to keep agent behavior within approved boundaries.
Zenity Labs targets vulnerabilities and zero-click risks
Zenity’s security work also extends through Zenity Labs, an internal effort focused on finding weaknesses in agentic AI platforms. The company specifically points to threats like zero-click attacks, which can hijack enterprise AI agents without obvious user interaction.
According to Zenity, these kinds of attacks could lead to data exfiltration and even system compromise. The inclusion of this research track suggests the company is treating agent security as a continually evolving discipline—where new exploit paths can emerge as AI frameworks and agent capabilities change.
With this funding, Zenity indicates it will expand Zenity Labs, supporting continued discovery and refinement of defenses.
Where the company operates and how it plans to use new capital
Zenity is based in Tel Aviv and employs 230+ people worldwide. The company runs a Research & R&D center in Tel Aviv, while its go-to-market efforts and operations are handled from New York.
The company says the new round will be used to advance product innovation and grow its presence globally. The stated priorities include broadening the reach of its implementation footprint and strengthening capabilities that support enterprise adoption.
What Norwest and its partners see in Zenity
Norwest partner Assaf Harel commented that enterprises are rapidly adopting AI agents across critical workflows. In that environment, he argues that organizations need a security approach built for a reality that is both new and continuously changing.
Harel also referenced Zenity’s early-mover positioning in end-to-end AI agent security, along with what he described as a strong and expanding presence among successful implementations for Fortune 1000 customers.
His remarks framed Zenity as a company positioned to lead a broader category, supported by real-world deployments and continued momentum.
Funding context in the broader security market
This Series C adds to a busy period for cybersecurity-focused startups, where investors are backing companies targeting practical risks created by modern technology. Recent funding mentions in the same news context include other firms working on security infrastructure and enterprise risk management, reflecting continued demand for tools that protect organizations from emerging threats.
For Zenity, the emphasis is specifically on the security layer for agentic AI systems—a segment where many organizations are still building internal policies, testing procedures, and monitoring practices.
What this could mean for enterprise AI teams
For IT, security, and governance teams, the shift to agentic AI raises immediate questions: Who authorizes what an agent can do? How do you prevent unintended actions? How do you handle compromised instructions or unexpected agent behavior?
Zenity’s announced focus on deterministic allow/modify/block behavior and its ability to distinguish legitimate work from manipulated activity aims to address those questions at the action level. Its support across multiple enterprise AI environments and platforms suggests the company is targeting the complexity that comes with real enterprise AI deployments.
Meanwhile, the work of Zenity Labs—particularly around zero-click style threats—signals that Zenity is investing not only in operational defenses, but also in understanding how attacks may evolve.
Conclusion
Zenity’s $125 million Series C round, led by Norwest and joined by strategic investors, underscores growing interest in AI agent security that can be enforced in real time. With total funding reaching $180 million, the company plans to accelerate product innovation, expand Zenity Labs, and grow its global footprint.
As enterprises adopt AI agents for higher-stakes workflows, platforms designed to control agent intent and action—while also researching vulnerabilities—may become increasingly important. Zenity’s new funding positions it to push further in that direction.
