TL;DR: As authorization logic sprawls across services, duplicated policy creates inconsistent decisions, weaker auditability, and unintended privilege, according to Cerbos. A decoupled authorization layer gives teams one governed policy source, local enforcement, and decision-level evidence without tying access control to application code.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “A shared authorization layer that adapts to context”.
Key questions
Q: What breaks when authorization logic is scattered across microservices?
A: Scattered authorization logic creates inconsistent enforcement, hidden exceptions, and audit gaps.
Q: Why does local authorization enforcement matter for machine identities?
A: Machine identities often need access decisions at runtime speed, and a remote control plane can become a bottleneck or a bypass target.
Q: How do security teams know if agent authorization is actually working?
A: Authorization is working only if the agent can complete the intended task without gaining unnecessary reach.
Practitioner guidance
- Centralise authorization policy ownership Define authorization once, assign explicit owners, and version the policy separately from application code so changes are reviewable and testable.
- Instrument decision-level audit trails Log the matched rule, relevant attributes, and active policy version for every access decision so investigators can explain outcomes instead of inferring them.
- Separate enforcement from application logic Keep applications asking the question at runtime while the authorization layer evaluates policy locally, avoiding per-service reimplementation and bypass pressure.
Bottom line: Duplicated authorization logic creates inconsistent access decisions, weak auditability, and unintended privilege across service boundaries.

Authorization sprawl is a governance failure before it is a code problem. When policy lives in multiple services, the organisation no longer has one accountable source of truth for access decisions. That breaks ownership, version control, and review discipline at the point where access is actually granted. The practitioner implication is that authorization needs the same governance treatment as any other shared control surface.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: What is the difference between shared authorization and shared application libraries?
A: Shared libraries standardise code reuse, but they do not guarantee one governed decision model. A shared authorization layer separates policy from application logic, so the same rule can be reused, versioned, audited, and enforced consistently across services. That is a control distinction, not just an implementation preference.
