TL;DR: Centralized policy visibility is essential for zero trust, compliance, and effective authorization because organisations cannot govern access they cannot see, according to PlainID. For IAM and NHI programmes, the real issue is not policy quantity but whether decisioning, auditability, and least-privilege enforcement are actually observable.

Questions worth separating out
Q: How should security teams centralize authorization policies without losing control?
A: Centralize the visibility of policy decisions before centralizing every enforcement engine.
Q: Why does policy visibility matter for zero trust programmes?
A: Zero trust depends on continuous verification, but verification is weak if access logic is fragmented and opaque.
Q: What breaks when authorization policies are not discoverable?
A: Teams lose sight of conflicting rules, stale exceptions, and duplicate access paths.
Practitioner guidance
- Map all authorization decision points Inventory where access decisions are made across SaaS, data platforms, and internal policy engines so teams can see duplicated rules and conflicting enforcement paths.
- Review policies for business readability Rewrite complex rules in plain language so data owners, audit teams, and security architects can challenge access logic without decoding implementation syntax.
- Test policy changes before production rollout Use simulation to check whether a new rule blocks legitimate access, preserves least privilege, and avoids introducing exceptions that are hard to detect later.

Policy visibility and authorization control: what IAM teams miss?

Visibility is the control, not the dashboard. The article is right to centre visibility, but the deeper governance point is that authorization cannot be trusted unless decision paths are auditable end to end. When policy logic is split across SaaS platforms, data stores, and business units, the organisation may believe it has least privilege while actually running on unverifiable exceptions. The implication is that authorization governance fails first as a measurement problem, then as a control problem.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which shows how often identity governance still operates without a complete control picture.
A question worth separating out:
Q: Who should be accountable for policy decisioning in IAM?
A: Accountability should sit with both security and the business owners of the data or application being protected. Security teams own the control design and evidence, while data owners validate whether access intent still matches operational need. That split keeps authorization decisions tied to real risk rather than technical convenience.
