NHI governance gaps in IAM: what teams should fix first

TL;DR: Mismanaged access, overprivileged identities, and static credentials are expanding attack surface as modern infrastructure shifts toward NHIs and cloud-native workflows, according to Apono’s analysis. The governance problem is no longer just access control at rest, but whether IAM can continuously discover, scope, and revoke machine access fast enough to matter.

By the numbers:

• 38% of breaches trace back to stolen credentials.
• In healthcare, insiders abusing privileged access accounts account for 70% of breaches.

Questions worth separating out

Q: How should security teams implement JIT access for non-human identities?

A: Start by making privilege temporary by default.

Q: Why do service accounts and API keys increase IAM risk?

A: Service accounts and API keys increase risk when they are long-lived, overprivileged, or poorly owned.

Q: What breaks when organisations rely on manual access reviews for NHIs?

A: Manual access reviews break down when identities are created dynamically and change faster than the review cycle.

Practitioner guidance

• Inventory every non-human identity and assign ownership Build a continuously updated inventory of service accounts, API keys, tokens, certificates, and pipeline identities.
• Replace standing secrets with short-lived credentials Use ephemeral tokens for deployments, admin tasks, and machine-to-machine access.
• Enforce task-scoped JIT for privileged access Make elevated access temporary, approval-based, and automatically revoked when the task ends.
