TL;DR: PlainID’s analysis of Zscaler ZPA finds access control becomes unreliable when policy decisions, token enrichment, and enforcement points do not share the same authorization model. Governance has to choose one authoritative layer and verify that every downstream control enforces the same entitlement logic.
Editorial analysis by NHI Mgmt Group, based on content published by PlainID: “Enhance Zscaler ZPA with PBAC”.
Key questions
Q: Why do token claims matter in identity-aware SASE enforcement?
A: Token claims matter because they often become the enforcement input once the authorization decision leaves the identity layer.
Q: What breaks when access policies exist in multiple SASE tools?
A: Policy sprawl creates contradictory rules, duplicate exceptions, and hidden ownership gaps.
Q: How should teams centralise authorization for SASE access control?
A: Teams should centralise the policy decision, not just the policy storage.
Practitioner guidance
- Define one authorization source of truth Assign ownership for policy decisions before distributing them across SASE, application, and data enforcement points.
- Audit token claims for entitlement fidelity Inspect whether the claims added during token enrichment match the intended policy outcome, especially for read-only or fine-grained access.
- Inventory existing access policies before orchestration Catalogue native policies already present in SASE and adjacent tools, then identify duplicates, overrides, and orphaned rules.
Bottom line: SASE access control becomes unreliable when policy decisions, token enrichment, and enforcement points do not share the same authorization model.

SASE authorization only works when the policy decision and the enforcement claim are the same thing. PlainID's model highlights a familiar IAM failure pattern: organisations assume central policy logic will stay intact after translation into tokens and edge enforcement. In reality, the risk is policy drift across layers, where one system authorizes and another enforces a different interpretation. The practitioner conclusion is simple: identity-centred SASE depends on a single authoritative authorization model, not just an integration path.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How do teams know whether SASE authorization is actually aligned?
A: Teams should test the full chain from policy source to token enrichment to enforcement. Alignment is real only when the same access request produces the same entitlement meaning across every layer. If the decision changes as it moves through the stack, the organization has orchestration, but not reliable authorization governance.
