TL;DR: Externalized authorization still breaks when teams rebuild context differently in every application, especially as AI agents enter the decision path, and Cerbos Synapse adds a data integration layer in front of its policy engine so identity, resource, and relationship data can be enriched before each authorization decision, reducing per-service plumbing and making context resolution auditable according to Cerbos.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “Introducing Cerbos Synapse: unified authorization context and enforcement across your stack”.
Key questions
Q: How should teams handle authorization when identity context is assembled from multiple systems?
A: Teams should centralise context resolution so the policy engine receives a complete request with identity, resource, and relationship attributes before evaluation.
Q: Why do AI systems make authorization harder to govern than traditional applications?
A: AI systems can turn one request into many downstream actions across tools, data sources, and APIs, which means the access question is no longer a single login event.
Q: What breaks when authorization is rebuilt inside each service?
A: Consistency breaks first, then visibility and reviewability.
Practitioner guidance
- Centralise authorization context resolution Move identity, resource, and relationship lookups into one governed layer so services stop rebuilding the same attributes independently before each policy decision.
- Separate policy evaluation from data fetching Keep the PDP free of external calls and make cache, fallback, and freshness choices explicit in the enrichment layer instead of hiding them in policy code.
- Model delegated AI requests explicitly Ensure agent requests carry both the human delegator and the agent runtime scope so policy can evaluate delegated access without guesswork or hard-coded exceptions.
Bottom line: Authorization fails when identity and resource context is rebuilt differently in every service, because the policy engine never sees one governed version of the truth.

Authorization context is now a governance layer, not an implementation detail. Once every service rebuilds identity and resource attributes for itself, organisations lose a common control point for how authorization decisions are formed. That creates audit gaps even when the final policy logic is sound. The practical conclusion is that context resolution needs explicit ownership, change control, and observability just like the policy engine itself.
A question worth separating out:
Q: How do you know whether an authorization enrichment layer is working well?
A: It is working when the PDP receives consistent context, lookup latency stays visible, and teams can trace which systems supplied each attribute. If decision inputs differ by service, or if freshness and fallback behaviour are hidden inside application code, the control is not operating as a shared capability.
