TL;DR: Azure security outcomes depend less on the platform layer than on who can do what across Entra ID, RBAC, ABAC, and non-human identities, according to Veza’s checklist. The operational problem is effective permissions drift, where inheritance, group sprawl, and durable credentials quietly expand blast radius beyond what role assignments suggest.

By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
Questions worth separating out
Q: What breaks when Azure teams rely on assigned roles instead of effective permissions?
A: Assigned roles can hide inherited access, nested group grants, and data-plane actions that materially widen what an identity can do.
Q: Why do non-human identities make Azure access reviews less reliable?
A: Non-human identities do not change jobs, leave the company, or naturally trigger revocation workflows, so they keep durable access long after the original need has passed.
Q: How do security teams know whether least privilege is actually working?
A: Least privilege is working when identities have narrowly scoped permissions, unused credentials are removed or quarantined, and repeated access reviews consistently shrink entitlements.
Practitioner guidance
- Map effective permissions, not intended roles Generate tenant-wide views that reconcile direct grants, inherited access, group membership, and custom role data actions before you certify access or approve exceptions.
- Put expiry on all temporary elevation Require time-bound elevation for admins, break-glass accounts, guest access, and service credentials that exist only for a project or incident.
- Inventory and scope non-human identities Inventory service principals and managed identities, then assign the smallest viable scope and revoke rights that are no longer tied to an active workload.

Effective permissions are the real security boundary in Azure. Role names and assignment intent are not enough once inheritance, group nesting, and data-plane actions stack together. The operational question is not who was granted access in theory, but what actions an identity can actually execute across scopes. Practitioners should treat effective permissions as the governing unit of risk.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to Ultimate Guide to NHIs.
- 79% of organisations have experienced secrets leaks, and 77% of those incidents caused tangible damage.
A question worth separating out:
Q: Who is accountable when over-privileged Azure identities create a breach path?
A: Accountability sits with the programme that owns identity governance, cloud configuration, and lifecycle control, not with the cloud provider alone. Azure secures the platform layer, but organisations decide who can do what inside it. That means IAM, cloud security, and control owners all share responsibility for effective permissions, revocation, and evidence.
