TL;DR: ISO 27001 audits depend on documented controls, repeatable evidence, and independent review, and StrongDM’s guide shows why stage 1 design review, stage 2 field testing, surveillance audits, and recertification all hinge on proving controls work in practice, not just on paper. For IAM teams, the lesson is that auditability becomes an operational requirement across human, NHI, and privileged access programmes.
NHIMG editorial — based on content published by StrongDM: ISO 27001 Audit: Everything You Need to Know
By the numbers:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
Questions worth separating out
Q: How should security teams prepare privileged access evidence for ISO 27001 audits?
A: Security teams should ensure privileged access decisions, session logs, approvals, and remediation records are centralized and tied to named control owners.
Q: Why do access logs matter so much in ISO 27001 certification?
A: Access logs matter because ISO 27001 audits verify that controls work in practice, not just on paper.
Q: What breaks when audit evidence is fragmented across IAM and PAM tools?
A: Fragmented evidence breaks the auditor’s ability to verify that access controls were followed consistently.
Practitioner guidance
- Map audit evidence to control owners Assign a named owner for each ISMS control, then link access approvals, session logs, and remediation records to that owner so auditors can trace evidence without manual reconstruction.
- Centralize privileged access records Keep sessions, queries, and commands in one reviewable record set so stage 2 sampling does not depend on piecing together data from separate tools and teams.
- Align lifecycle controls with surveillance audits Schedule access reviews, offboarding checks, and evidence retention so they happen on a cadence that supports surveillance sampling instead of ad hoc cleanup.
What's in the full article
StrongDM's full guide covers the operational detail this post intentionally leaves for the source:
- A step-by-step breakdown of stage 1 and stage 2 audit preparation for teams building an ISO 27001 evidence pack.
- Practical guidance on internal versus external auditors and how certification bodies expect evidence to be presented.
- Timeline expectations for initial certification, surveillance audits, and recertification across different organisation sizes.
- Examples of the control and documentation areas auditors commonly sample during review.

ISO 27001 audits expose the evidence gap, not just the control gap. The article is really about proving that security controls operate consistently enough to satisfy an external reviewer. That matters across human IAM, PAM, and NHI governance because the same failure mode appears when ownership, logs, or lifecycle records are too weak to verify. Practitioners should read this as an evidence-design problem, not an audit-calendar problem.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why audit-grade identity evidence remains hard to assemble.
A question worth separating out:
Q: Who is accountable when ISO 27001 controls do not match actual access behaviour?
A: Accountability sits with the control owner and the organisation’s governance function, because ISO 27001 expects documented controls to reflect real operations. If access behaviour differs from policy, the issue is not only technical. It is a governance failure that auditors will surface through sampling, interviews, and recertification evidence.
