TL;DR: PlainID’s August 31 analysis argues that enterprises need a phased authorization model because fragmented policies, weak visibility, and expanding API, data, and AI workflows make wholesale rewrites unrealistic. Centralized policy infrastructure, inventorying current sprawl, and then extending control into tokens, APIs, data, and agentic AI creates a workable modernization path.
Editorial analysis by NHI Mgmt Group, based on content published by PlainID: “How to Get Started with Authorization Strategy”.
Key questions
Q: What should security and application teams focus on first when modernizing authorization?
A: Focus first on use cases that can show value quickly, especially new applications or teams already moving toward modern practices.
Q: Why does authorization sprawl create risk across APIs, data, and AI workflows?
A: Because the same access logic ends up implemented differently in many places, teams lose visibility into which rule is authoritative and where enforcement varies.
Q: What breaks when authorization rules stay embedded in code?
A: Governance breaks first, because access logic becomes scattered across services and harder to review consistently.
Practitioner guidance
- Map authorization decision points Identify where access decisions are currently made across applications, APIs, data stores, and AI workflows, then document which identity types depend on each path.
- Centralise policy administration first Establish a shared policy administration point and runtime decision layer before trying to standardise every application at once.
- Prioritise token and API quick wins Target token-based authorization and high-traffic APIs early, because they provide fast control gains without a wholesale rewrite.
Bottom line: Authorization modernisation is a control-plane problem because policy sprawl across applications, APIs, data, and AI makes embedded access logic unmanageable.

Authorization has become a policy-plane problem, not a feature-level control. The article is right to frame modern authorization as infrastructure because the old model of embedding rules inside each application cannot keep pace with APIs, data platforms, and AI workflows. Once access decisions are spread across dozens of systems, consistency becomes a governance issue as much as a technical one. Practitioners should treat authorization as a shared control plane that must be designed, not patched.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should teams govern agentic access when AI systems move faster than access reviews?
A: Teams should move governance earlier in the lifecycle and treat issuance, delegation and device trust as the main control points. Access reviews still matter, but they cannot be the only safeguard when an agent can request, use and release access inside a single task. The practical aim is to make approval, scope and attribution visible before execution starts.
