Authorization was always the gap. AI is making it impossible to ignore.

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.

AI agents blur identity lines

AI agents blur identity lines

AI agents act on behalf of users through MCP clients and other interfaces, masking who initiated the action. When the system can’t tell them apart, agents inherit permissions they should never have.

Standing access never expires

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

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

"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."

Fine-grained identity security

Why teams choose 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."

"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."

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."
