Identity

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

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

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.”

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

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

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

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.”

— Gartner, Tech FutureSight: Enterprise AI Scaling Requires Solving Agentic Identity

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.

Implementing Zero Trust with Cerbos

Why teams love Cerbos

Chuck Hardy company logo

"When I did an audit, I found that the cost of managing authorization and authentication in-house over the entire lifespan of the company was in the 7 figures. Cerbos saved that. Deploying Cerbos has allowed our engineers to spend their time on what really matters for our success."

"Having to modify authorization is a five-minute job now. Having to troubleshoot authorization is a five-minute job. So that has actually allowed the team to spend more time where it really matters on the platform."

"We went from one user - every role, to a world where there are many users - many roles. And the product, it relies on Cerbos to actually bring the value that we want to bring to customers. All of our customers are relying on Cerbos, by relying on the product, which is of course relying on Cerbos."

"Having the separation of the permissions from the code base just makes the code base more elegant. It makes the permissioning more elegant. It means they're centralized, so they're not tied to specific endpoints. And ultimately it means that different business owners have the ability to actually make updates."
