Policy-driven authorization at the Traefik proxy
Enforce fine-grained Cerbos authorization policies at the Traefik edge — before requests reach your services.
Native Traefik support
Cerbos integrates with Traefik's ForwardAuth middleware, no custom glue code required
Unified policies
The same CEL-based policies that govern your application layer extend to your infrastructure
Defense in depth
Authorization at every layer of your stack, managed from a single control plane
How Cerbos works with Traefik Proxy
Enforcing authorization at the Traefik Proxy gateway means unauthorized requests are rejected before they reach your services, reducing load, improving security posture, and simplifying backend code.
Cerbos provides fine-grained, context-aware authorization policies written in human-readable YAML. When integrated with Traefik Proxy, these policies are evaluated at the edge for every incoming request.
The same Cerbos policies govern authorization at the gateway and within your services, one source of truth, one audit trail, and consistent enforcement across every layer.
How Cerbos works with Traefik
- Deploy Cerbos alongside Traefik, Run the Cerbos PDP as a sidecar or service accessible from your Traefik proxy.
- Configure the ForwardAuth middleware, Set up Traefik to call Cerbos on incoming requests, passing identity and request metadata.
- Define authorization policies in YAML, Write policies that control access based on routes, methods, roles, and request attributes.
- Requests are authorized at the edge, Unauthorized requests are rejected before reaching your services, reducing load and improving security posture.
FAQ
How does Cerbos work with Traefik?
Traefik calls the Cerbos PDP for every incoming request. Cerbos evaluates your authorization policies using the request context (headers, claims, path) and returns an allow or deny decision, all at the gateway edge.
Does this replace backend authorization?
Gateway-level authorization provides defense in depth. You can enforce coarse-grained policies at the edge and fine-grained policies within your services, both managed by Cerbos.
