Onyx Security
Control plane for enterprise AI agents: finds sanctioned and shadow agents, watches what they try to do, and blocks harmful actions before they run.
About Onyx Security
Onyx gives security and AI teams one place to see and govern the AI agents running across a company, whether bought from a vendor or built in-house.
It discovers agents and shadow AI across SaaS, cloud, and endpoints, follows each step of an agent's reasoning and tool use, and can intervene before an unintended or malicious action executes.
Policies are written in natural language, and the platform covers prompt injection defense, agent identity and access, and MCP server security. The company reports more than 1.1 million agents under protection and offices in Tel Aviv and New York.
