Identity sprawl and correlation gaps: what IAM teams are missing

TL;DR: Enterprises are accumulating IAM, IGA, PAM, directory, and NHI tools that each model identity differently, creating fragmented visibility and unmanaged aliasing across systems, according to AuthMind. The real problem is not account volume but broken correlation, which leaves privilege escalation paths and shadow access hidden from governance.

NHIMG editorial — based on content published by AuthMind: identity sprawl and the mechanics of identity observability

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.

Questions worth separating out

Q: How should security teams reduce identity sprawl across human and machine accounts?

A: Start by building a unified identity inventory that links each account to one owner, one purpose, and one environment.

Q: Why do synchronised identity systems still leave risk behind?

A: Because synchronisation moves data between systems without proving that each record refers to the same actor.

Q: What do teams get wrong about shadow access?

A: They often treat shadow access as a discovery problem only, when it is also a correlation problem.

Practitioner guidance

• Map duplicate identities across systems Inventory every human, service account, and agentic identity across directory, cloud, PAM, and local systems, then reconcile aliases to one accountable owner.
• Audit shadow accounts and local admins Search for unmanaged local accounts, dormant production IDs, and non-directory admin access that survive offboarding or bypass PAM controls.
• Correlate activity with ownership records Require every privileged action to resolve back to a named owner, creator, or operator, especially where non-human identities are involved.
