Onyx Security Onyx Security builds a secure AI control plane for enterprises deploying autonomous agents and models. Its platform discovers AI assets across SaaS, cloud, endpoints and code, monitors agent reasoning and actions, and enforces security and governance policies at runtime. Supervisory agents and proprietary models can block unsafe actions, require human approval, narrow an agent’s permissions or redirect its behavior. The platform combines AI observability, security, governance, orchestration and usage measurement.
