Authorization management platform
Authorize every identity. Govern every decision.
Enforce fine-grained, contextual, and continuous authorization across applications, gateways, workloads, and AI agents.
Security
Engineering
IAM
See and govern every access decision
Gain full visibility into what every identity can access. No more scattered authorization logic creating blind spots.
Control AI agent access
Define boundaries before AI agents go live. Revoke access in seconds through policy. Always know exactly what every agent can access.
Prove compliance at any time
Get instant logs for every decision: who, what, when, which policy. Audit-ready for SOC 2, ISO 27001, HIPAA, GDPR, NIS2, DORA, FedRAMP.
Control authorization logic in one place
Define, approve, and update policies centrally. Replace scattered if-statements with a single function call.
Ship authorization in one sprint
Deploy roles and permissions without code changes. RBAC, ABAC, ReBAC, PBAC supported out of the box.
Scale with your architecture
Handle millions of authorization decisions per second across distributed systems and real-time AI agents. Stateless, deploys anywhere.
Close the gap in your IAM stack
Your IdP authenticates. Your IGA provisions roles. Cerbos controls what identities actually do at the resource level, at runtime.
Govern every identity type
Manage access across your entire identity fabric in one place. Centralized policies for users, service accounts, NHIs, and AI agents.
Secure AI agents with guardrails
Define what each AI agent can access before it goes live - and revoke that access in seconds through policy if anything changes.
Authorization was always the gap. AI is making it impossible to ignore.
Over-permissioned access
AI agents and services can do more than they should. One mistake can expose sensitive data or trigger unauthorized actions.
AI agents blur identity lines
AI agents act on behalf of users but mask who initiated the action. When the system can't tell them apart, agents inherit permissions they should never have.
Standing access never expires
Long-lived tokens and shared credentials stay valid long after they are needed, increasing the chance of compromise.
No fine-grained kill switch
If an agent goes beyond its scope, access continues until someone rotates credentials or restarts systems. No way to revoke a single action in seconds.
Access control for every use case
Single authorization management platform for every identity, every decision, at every layer.

Authorization loved by engineers and leadership
For managers
For engineers
"We can trace every permission, investigate suspicious behavior, and answer questions about who did what, when, and why. We’ve gone from guesswork to forensic-level auditing across humans, machines, and everything in between."
Rob Crowe, Principal Engineer
Time to market
100x faster launch
Deploy new roles and permissions instantly for RBAC, ABAC, ReBAC, PBAC.
Security
Enable AI adoption safely
Define what every AI agent can do and access. Revoke permissions in seconds.
ROI
Skip the 12 months build time
Eliminate the need to design, operate, and evolve authorization in-house.
Compliance
Audit-ready logs
Log every allow/deny decision with fine-grained context. Full traceability across all identities.
Why Cerbos? To control what happens after login.
Your IdP authenticates. Your IGA provisions roles. Cerbos controls what identities are allowed to do, at the moment decisions are enforced.

Cerbos PDP
Policy Decision Point
PDP is an open source authorization engine that evaluates requests against policies and returns access decisions. It's stateless, high-performance, and built to scale horizontally.
Native SDKs
Cerbos PEP SDK
Policy Enforcement Point
Cerbos PEPs are language-native client libraries that connect applications directly to PDPs to enforce real-time access decisions, with SDKs available for all major languages.

Policy based access control at scale
Purpose built authorization, not a generic policy engine
 Generic policy engines |  Cerbos | |
|---|---|---|
Policy language General-purpose policy languages designed for broader use cases. | Policy language YAML policies purpose-built for authorization, readable by security teams. | |
Authorization model Authorization patterns must be assembled from generic primitives. | Authorization model First-class RBAC, ABAC, PBAC, and ReBAC with principal/resource/action semantics. | |
Evaluation latency Varies by policy complexity and engine architecture. | Evaluation latency Sub-millisecond, optimized for per-request evaluation at machine speed. | |
Policy lifecycle Custom sync, manual distribution, separate CI/CD tooling. | Policy lifecycle Cerbos: managed policy lifecycle with CI/CD, testing, and real-time distribution. | |
Audit and compliance Decision logs require additional infrastructure to capture and correlate. | Audit and compliance Structured decision logs with policy version lineage, built in. |
Authorization for enterprise software and AI
Externalized, policy-based, runtime authorization for your apps, enterprise software, AI systems and workflows.
