Onyx Security just raised $113 million at a $640 million valuation, four months after coming out of stealth. The round, led by Bessemer, brings total funding to $153 million since the company launched in 2024. The headline number is revenue quadrupling in those four months, according to the announcement.

What Onyx does is simple. It sits between your AI agents and the systems they touch. When an agent tries to do something, Onyx inspects the action and blocks it if it looks risky. Think of it as a security layer for autonomous tools that can now book meetings, update databases, or move money without a human signing off each time.

The speed of this raise and the explicit mention of revenue growth tell you something concrete. Enterprises are deploying agents fast enough that “who watches the agents” is now a paid problem, not a theoretical one. Companies want the productivity boost from automation, but they also want a kill switch and an audit trail. Onyx is selling that peace of mind, and buyers are showing up.

If you’re running operations and starting to hand tasks to AI, this is the kind of guardrail you’ll want baked in from the start. It’s not enough to know what an agent can do. You need to know what it’s actually doing and have a way to stop it when it drifts. That’s the kind of oversight we build into the Omni Command Centre, so you’re not flying blind when you scale automation. The market for agent control is here, funded, and growing faster than most people expected.
