AI gateway authorization
Govern every AI gateway request, agent, and delegation
Control which LLMs, tools, and agents each identity can reach through your AI gateway.

IAM
Prove what every agent did, on what resource, on whose behalf
Every model call, tool use, agent-to-agent request runs through one policy layer. Auditors get one trail across humans, services & agents, in the same format as your app audit log.
No standing privilege for non-human identities
Agents and service accounts only get the access the policy allows at the moment of the request. Pull access on the next call, no token rotation, no redeploy.
Regulator-ready evidence by default
Decision, policy version, principal, resource, and delegation chain captured for every AI request. SOC 2, ISO 27001, HIPAA, NIS2, and DORA traceability without manual reconstruction.
AI gateways route the traffic. Authorization decides what gets through.
Your AI gateway authenticates the caller. It doesn't decide what that caller can do. Those decisions live inside applications, where identity and security teams have no visibility and no way to change them.
Your gateway authenticates. Your apps authorize.
Once a request passes the gateway, every authorization decision lives in application code. Identity and security teams have no visibility into it and no way to change it.
The human behind the agent disappears.
When an agent acts on a user's behalf, the user vanishes from the audit trail. Auditors see a service account, not the person who triggered the action.
Sub-agents inherit everything.
When one agent hands work to another, the second one picks up the full authority of the first. Capabilities expand silently, far beyond what the original request justified.
Revoking access is a fire drill.
Without one policy layer, pulling an agent's permissions means rotating credentials, editing gateway config, or redeploying. Until that's done, the agent keeps acting on the access you're trying to revoke.
Build your AI gateway authorization strategy
Control access for every AI interaction, at any scale
Govern every model call, tool invocation, MCP method, and agent-to-agent delegation the gateway routes, with the same policies that govern the APIs and data systems behind it.

Threat detection
“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.”

Put a policy engine alongside your AI gateway
Identity systems establish who someone is. Cerbos decides what they are allowed to do, at the moment the gateway enforces it.
1
Every AI request goes through Cerbos first
When a user invokes an agent, an agent calls a tool or a model, or one agent delegates to another over A2A, the gateway sends the request to Cerbos before routing the call upstream - through a native authorization hook, a pre-request plugin, or an external authorization filter.
2
Cerbos evaluates the full picture
It pulls in who is calling, on whose behalf, what they want to do, which model or tool is involved, and the surrounding context, identity, resource attributes, risk, and the delegation chain, through the IdP, IGA, and data sources you already run.
3
The gateway enforces the decision
Allow or deny lands at the gateway before the request reaches the provider, and every decision is logged with the policy version that produced it. For high-capability agents, the gateway fails closed if the policy layer is unreachable.
