What is Cerbos? Cerbos is an end-to-end enterprise authorization management platform 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 Point (Cerbos Hub) that coordinates unified policy-based authorization across your architecture; and an enrichment and orchestration point (Cerbos Synapse) which gathers identity, resource, and relationship data from your existing systems and delivers complete context to the policy engine before every authorization decision. Enforce least privilege & maintain full visibility into access decisions with Cerbos authorization.
