“In fintech, you’ve got to track and enforce who can access data and when. If you don’t do this correctly, you potentially open up unauthorized access.”
Edgar Rivera, CTO
Control access for every identity, at any scale
Enforce the same authorization logic consistently across apps, APIs, services, non human identities, and AI workflows.

Authorization can’t be an afterthought
Close security blind spots
Every transfer, approval, and data request depends on authorization logic. With Cerbos, authorization is policy-driven and auditable.
Stop uncontrolled money movement
Over-permissive roles or missing real-time checks allow unauthorized transfers. With Cerbos, every payment and approval is evaluated against policy at runtime.
Limit data access
AI agents, APIs, and backend services inherit broader access than required. PBAC enforces least privilege for customer and transaction data.
Accelerate compliance response
Cerbos enforces AML and KYC requirements through versioned access policies, enabling faster updates and clearer audit trails.

“It's weird to say an outside company has our back, but Cerbos does. It's the people. It's their open-source code: it's high quality, you can read it, it does what it says on the tin.”
