TL;DR: Hardcoded authorization logic creates duplication, audit friction, and maintenance risk as applications and AI-driven workflows scale, while policy-based externalized authorization centralises decisions and improves consistency, according to Cerbos. The governance shift is from embedding access logic in every app to treating authorization as a reusable control plane that IAM teams can actually govern.
NHIMG editorial — based on content published by Cerbos: a DevOps Paradox discussion on externalized authorization, policy-based access control, and AI data filtering
Questions worth separating out
Q: How should security teams govern authorization across multiple applications?
A: Security teams should move access decisions into a centrally managed policy layer, then assign ownership for policy design, testing, and exception handling.
Q: Why does hardcoded authorization become risky as systems scale?
A: Hardcoded authorization becomes risky because every new service or exception creates another copy of the logic.
Q: How can organisations apply zero trust to application authorization?
A: Organisations should apply zero trust by evaluating authorization on every request using current identity, resource, and context signals.
Practitioner guidance
- Centralise authorization policy ownership Assign a single control owner for authorization logic so policy changes, exceptions, and testing are managed consistently across services.
- Map high-risk decisions to policy conditions Separate simple role-based access from context-dependent access, then document which attributes influence each policy decision.
- Enforce retrieval-stage controls for AI workflows Require applications and AI-assisted workflows to check entitlements before data is retrieved or passed into prompts.

Externalized authorization is now an identity governance problem, not just an application design choice. Once access rules live inside every codebase, security and compliance teams lose a consistent control surface. The governance issue is not only duplication, but the loss of a single place to prove who can do what, under which conditions, and why. Practitioners should treat authorization policy as part of the identity control plane, not as an implementation detail left to developers.
A few things that frame the scale:
- 64% of valid secrets leaked in 2022 are still valid and exploitable today, proving that detection alone is not enough without automated revocation, according to The State of Secrets Sprawl 2026.
- Internal repositories are 6x more likely to contain secrets than public ones, with 32.2% versus 5.6% exposure rates in 2025.
A question worth separating out:
Q: What should teams do when AI systems need access to sensitive data?
A: Teams should require entitlement checks before retrieval so the AI only receives data the user is already allowed to access. This reduces overexposure, prevents unrestricted model ingestion, and keeps authorization aligned to the same identity rules used elsewhere in the platform.
