TL;DR: Moving authorization out of application code can be achieved by pairing a policy decision point with Azure API Management, so gateway policy can allow, deny, and inspect JWT claims before requests reach backend services, according to Cerbos. The governance lesson is that centralised decisioning helps consistency, but only if policy versioning, token validation, and audit logging are treated as part of the access model.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “Policy as Code with Azure API Management and Cerbos”.
Key questions
Q: How should teams implement API authorization when it is separated from application code?
A: Teams should define policy in a central decision point, enforce it at the gateway, and keep the backend focused on business logic.
Q: Why do gateway policies still need strong JWT validation?
A: Gateway policies still depend on identity assertions, so token integrity, issuer trust, and claim parsing have to be correct before any access decision is made.
Q: What breaks when authorization rules are scattered across gateways, services, and data systems?
A: When authorization rules are scattered, teams get inconsistent decisions, duplicated logic, and higher drift between intended and actual access.
Practitioner guidance
- Define authorization outside application code Move access rules into a shared policy layer so service teams stop reimplementing entitlement logic in each backend.
- Validate tokens at both control points Check JWT integrity and expiration at the gateway, then re-evaluate claims in the policy engine using trusted key material.
- Model broad and narrow access separately Use roles for coarse access such as authenticated or anonymous, then reserve claim-based rules for privileged actions like moderation or deletion.
Bottom line: Separating authorization from service code can reduce duplication, but it shifts the governance burden to policy lifecycle, token trust, and gateway enforcement.

Authorization policy has to be governed as infrastructure, not embedded logic. Once access rules move into a gateway and external policy engine, the control surface becomes versioned policy, not service code. That changes how teams review change, test enforcement, and prove consistency across APIs. The practical conclusion is that authorization becomes an independently managed identity control plane.
A question worth separating out:
Q: How should organisations choose between RBAC and ABAC for non-human identities?
A: Use RBAC for stable, repeatable access patterns and ABAC when access must change with context, resource type, or environment. For non-human identities, ABAC is usually better when workloads are ephemeral or shared across teams. The practical test is whether the access rule needs to follow the identity alone or the identity plus the conditions around it.
