Exclusive: Onyx Security brings AI agent governance to Glean’s enterprise AI platform

AI agent security startup Onyx Security Inc. today announced an integration with enterprise artificial intelligence platform company Glean Technologies Inc. to help enterprises govern the AI agents they build and run on Glean.

Onyx and Glean are pitching the integration at companies that are moving quickly to roll out autonomous, connected agents across their departments. Onyx claims, however, that most of them are not yet prepared to manage the risks that agents bring.

According to Onyx, security teams now need to keep continuous track of agent access, actions and policy compliance. Under the partnership, Glean provides the platform to build, deploy and operate the agents, while the Onyx secure AI control plane is used to extend governance and security across the AI environment.

At the core of the integration is discovery, with Onyx able to inventory every Glean agent and the access and capabilities it holds. Ownership, business purpose and a risk classification can then be assigned to each agent, according to the companies.

Enterprise AI governance and compliance policies can also be applied through the integration, after which Onyx continuously assesses changes to the permissions, tools and data access granted to each agent. Intent-aware runtime controls, which Onyx applies to prompts, responses and agent actions, provide protection while the agents are running.

Unsafe requests can be blocked outright under the controls. In other cases, the controls are said to steer unintended agent actions back in line with company policy. Centralized audit evidence is also maintained across AI environments. From deployment through ongoing operation and expansion, the companies say, agents fall under a single governance model.

“As agents gain greater access and autonomy, security teams need visibility and control over what they can do,” said Gil Elbaz, co-founder and chief AI officer at Onyx, who previously worked under Nvidia Corp.’s chief technology officer. “By combining Glean’s enterprise context with Onyx’s security control plane, customers can govern agent activity consistently and confidently across their AI environment.”

Glean regards context and governance as “foundational to making enterprise AI both useful and trustworthy,” according to Zubin Irani, the company’s vice president of partnerships. The Onyx integration is said to build on that foundation as organizations deploy agents across their business.

Coming into the partnership, Onyx has raised $153 million to date, including a $113 million Series B round led by Bessemer Venture Partners in July. The company launched in March with $40 million in seed and Series A funding.

Glean, for its part, last raised $150 million in a Series F round at a valuation of $7.2 billion in June 2025.

Irani spoke with theCUBE, SiliconANGLE Media’s livestreaming studio, in June about how Glean’s AI platform leverages enterprise data to power models and agents:
