TL;DR: Choosing an auditor for access management and compliance work comes down to accreditation, framework experience, technology use, communication, and cost, according to Zluri. For identity teams, the real issue is whether the audit partner can validate controls across human access, NHI governance, and access review evidence without slowing the programme down.

By the numbers:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.
- Only 5.7% of organisations have full visibility into their service accounts.
Questions worth separating out
Q: How should security teams choose an auditor for access management programmes?
A: Choose an auditor who can prove framework competence, assess access evidence end to end, and understand how entitlement changes are governed across the identity lifecycle.
Q: Why do access review and offboarding processes matter during an audit?
A: Because auditors are testing whether access was actually controlled, not whether a policy exists.
Q: What is the biggest mistake teams make when selecting an auditor?
A: The most common mistake is optimising for brand recognition instead of fit for the actual control environment.
Practitioner guidance
- Validate framework coverage before engagement Confirm the auditor can test the specific frameworks you actually need, including how they handle access evidence, exception tracking, and remediation records across each scope.
- Demand evidence lineage for access reviews Require a clear trail from entitlement approval to recertification to revocation, with timestamps and ownership recorded in a way that can be reproduced during audit.
- Test whether the auditor can follow NHI lifecycle records Ask how they will inspect service accounts, API keys, and certificates alongside human access, so non-human entitlements do not disappear from the audit population.
