What is Cerbos?

Cerbos is an end-to-end enterprise authorization software for Zero Trust environments and AI-powered systems. It enforces fine-grained, contextual, and continuous authorization across apps, APIs, AI agents, MCP servers, services, and workloads.

Cerbos consists of an open source Policy Decision Point, Enforcement Point integrations, a centrally managed Policy Administration Plane (Cerbos Hub) that coordinates unified policy-based authorization across your architecture, and a built-in data integration and enrichment layer (Cerbos Synapse). Enforce least privilege and maintain full visibility into access decisions with Cerbos authorization.
