AI agents carry minimal identity context. Cerbos fills the gap.

When an agent acts on behalf of a user, Cerbos enriches the request with the user’s full identity, session, and resource context for fine-grained authorization decisions.

Identify the human behind every agent request

Identify the human behind every agent request

Synapse can fetch the delegating user's profile from your IdP and pass both identities to the policy engine in one call.

Evaluate agent and human together

Evaluate agent and human together

One policy call evaluates what the agent is allowed to do and whether the user behind it is authorized to trigger that action.

No standing privilege for non-human identities

Access is never assumed from a previous decision. Every agent request is checked against the current policy at request time.

Let agents discover what's allowed

Query planning returns the full set of resources an agent can access on behalf of a user, with the same enrichment applied.

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 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."

"The main reason we switched to Cerbos was to have a sophisticated authorization software to help organize and handle our authorization. We wanted to focus on domain related features and spend less time backtracking and fixing issues with our authorization."

"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."
