TL;DR: Permanent privileged roles in Entra ID can create tenant-wide control when they are treated as normal access, Oleria Security says. Governance has to keep pace with directory changes, or reviews will miss the standing access and app reach that widen the blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Oleria Security: “Identity security & governance for Microsoft Entra ID”.
Key questions
Q: Why do over-permissioned apps and service principals increase Entra ID risk?
A: Because app and service principal permissions can act like delegated privilege, especially when they can read or modify directory objects through Microsoft Graph.
Q: How do security teams tell whether Entra ID access certification is actually working?
A: It is working when reviews catch standing privilege, dormant service principals, stale guest access, and role assignments that no longer match actual use.
Q: What breaks when Entra ID ownership and privileged roles are not tightly governed?
A: Ownership over apps, groups, and service principals can become an escalation path when it is not treated as a privileged control.
Practitioner guidance
- Convert standing admin roles to task-scoped access Review Global Admin, Exchange Admin, and Conditional Access Admin assignments and remove permanent access where the role can be activated only when needed.
- Inventory service principals as governed NHIs Record owner, business justification, Microsoft Graph permissions, and credential expiry for every app registration and enterprise application.
- Reconcile effective access against usage logs Compare assigned roles, nested group membership, and audit log activity to find access that exists on paper but not in operations.
Bottom line: Microsoft Entra ID governance fails when permanent privileged roles are treated as normal access instead of high-impact exceptions.

Entra ID privilege sprawl is a blast-radius problem, not just an inventory problem. Permanent Global Admin, Exchange Admin, and Conditional Access Admin assignments turn one account into a control point for the entire Microsoft 365 environment. That changes the governance question from “who has access” to “how much damage can one identity still do if compromised.” The practitioner implication is that tenant-wide access must be managed as a high-impact exception, not a normal entitlement state.
A question worth separating out:
Q: Should teams prioritize role governance or service principal governance first in Entra ID?
A: Teams should start with the identities that can change the tenant fastest, which usually means permanent admin roles and over-privileged service principals. That sequencing reduces the largest blast radius first while exposing the hidden access paths that normal user governance misses. Once those are under control, guest access and group drift become easier to rationalize.
