Get visibility and control over what every user, service, and AI agent can do
Authorization for identity leaders who need to modernize access control, and secure AI before it ships.
The authorization layer your IAM stack is missing
Your IdP authenticates. Your IGA provisions roles. Cerbos controls what identities actually do at runtime.
Govern every identity type
Unified policies for users, service accounts, NHIs, and AI agents. One place to manage access across your entire identity fabric.
Your board has mandated AI. Your job is to make it safe
Define what each AI agent can access before it goes live - and revoke that access in seconds through policy if anything changes.
“We rely on Cerbos to make authorization decisions across the whole mesh - millions of times a day. And it's fast. We don't even think about it anymore. It just works.”
Rob Crowe, Principal Engineer
How authorization becomes your identity blind spot
You know who your users are. But what can they actually do? The authorization decisions inside your applications are fragmented, hardcoded, and invisible - creating gaps that auditors find and attackers exploit.
Your IdP stops at authentication
It verifies who someone is. But what they can do - at the resource level, at runtime - is scattered across application code, invisible to governance.
JML processes don’t reach permissions
Your IGA provisions roles. But the actual authorization decisions - what data users see, which actions they perform - live in code, outside your identity lifecycle.
The board bought AI. You inherited the access risk
Agents inherit broad permissions, mask who initiated actions, and create access paths your existing IAM stack can't detect, govern, or revoke.
“Through 2028, over 50% of AI initiatives will halt, becoming unmanageable, because of unresolved agentic identity challenges.”

Close the gap between identity and authorization
Cerbos adds contextual, continuous authorization to your existing IAM ecosystem - centralized control, real-time visibility, and instant revocability for every identity type.
Cerbos externalizes authorization logic from application code, making access control consistent and centrally managed across all your services. Your IdP authenticates and assigns roles. Cerbos evaluates fine-grained access decisions at runtime - per request, per resource, per action. Aligned to NIST SP 800-207 Zero Trust architecture.
How Utility Warehouse achieved full control and compliance across thousands of services and millions of NHIs with Cerbos.
SOC 2 & ISO audit-ready
AI agents secured
Threat detection
“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.”
