Onyx has raised $113 million in Series B funding to accelerate the development of its Secure AI Control Plane, a platform designed to help enterprises govern AI agents as they become increasingly embedded in business operations. The funding round was led by Bessemer Venture Partners, with participation from Cyberstarts, TCV, Conviction, FirstMark, Vintage Investment Partners, QuantumLight, and G Squared.

The investment will support Onyx’s mission of enabling organisations to maintain oversight of AI systems while allowing businesses to adopt autonomous technologies with confidence.

Building Governance for the Next Generation of AI

As AI agents become capable of performing more complex tasks across enterprise environments, the need for effective governance continues to grow. Onyx’s Secure AI Control Plane is designed to discover AI agents operating across browsers, endpoints, SaaS applications, and cloud environments while inspecting their actions before they are executed.

Rather than slowing AI adoption, the platform aims to provide enterprises with the visibility and control needed to deploy autonomous systems responsibly. According to the company, its technology already secures more than 1.1 million AI agents and monitors over 66 million AI sessions in real time across its enterprise customer base.

Addressing Risk in Critical Industries

Onyx sees its technology as particularly important for industries where AI-driven decisions can have significant real-world consequences. Sectors including financial services, healthcare, and energy increasingly rely on AI to support operational decisions, making governance an essential part of enterprise AI strategies.

The company believes that as organisations expand the use of AI agents, maintaining human oversight will become just as important as improving AI capabilities. The latest funding will help Onyx continue developing solutions that allow businesses to adopt advanced AI while reducing operational and governance risks.
