Launch production-ready AI systems with Cerbos

Identity systems establish who someone is. Cerbos controls what they are allowed to do, at the moment decisions are enforced.

How Cerbos authorization works - policy decision point architecture diagram

1

Every action is checked

When a user clicks a button, a service calls an API, or an AI agent uses a tool, the request is sent to Cerbos.

2

The request is evaluated

Cerbos reviews who is making the request, what they want to do, what they want to access, and the surrounding context.

3

The decision is enforced

Cerbos returns ALLOW or DENY. The application follows that decision before the action runs.

Access control for AI agents and every other use case

Cerbos is an authorization management platform that scales with your business.

Workloads

Weak authorization is how breaches start. AI scales the mistake.

Over-permissioned access

Over-permissioned access

AI agents and services can do more than they should. One mistake can expose sensitive data or trigger unauthorized actions.

Gaps between systems

Gaps between systems

When access rules live in different services, decisions become inconsistent. Attackers exploit those gaps.

Access that never expires

Access that never expires

Long-lived tokens and shared credentials stay valid long after they are needed, increasing the chance of compromise.

No way to stop it instantly

No way to stop it instantly

If an agent goes beyond its scope, access continues until someone rotates credentials or restarts systems.

Implementing Zero Trust with Cerbos

Why engineering 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 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."

Joe Lines company logo

"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."

"One of our big considerations was speed. We have strict latency tolerances. When it comes to Cerbos - you can call it a hundred times during a request and it doesn't matter. It's incredibly fast."

Henry Arnold company logo

"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."
