TL;DR: Maintaining ISO 27001 certification depends on recurring audits, control updates, training, and evidence collection across a three-year cycle, while StrongDM notes that failing to sustain compliance can raise breach risk and increase costs, including roughly $15,000 annually for internal and external auditing. The harder issue for IAM teams is that certification discipline often outpaces the governance reality of non-human identities.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “How to Maintain ISO 27001 Certification in 2026 and Beyond”.
By the numbers:
- Organizations must undergo ISO 27001 certification renewal every three years.
- ISO 27001 audit costs total roughly $15,000 annually.
Key questions
Q: What breaks when ISO 27001 maintenance does not cover non-human identities?
A: The certification model can still pass while service accounts, secrets, and certificates remain unmanaged.
Q: Why do recurring ISO 27001 audits not fully solve NHI governance?
A: Recurring audits measure whether controls are operating, but they do not automatically prove that non-human identities are inventoried, owned, or revoked on time.
Q: How do security teams know if NHI controls are actually working?
A: Look for complete inventory coverage, clear ownership, enforced rotation, and evidence that unused credentials are removed on time.
Practitioner guidance
- Inventory non-human identities as auditable assets Build a complete register of service accounts, API keys, tokens, certificates, and workload identities, then assign ownership and business purpose to each record.
- Tie certification evidence to NHI lifecycle events Require proof of creation, review, rotation, and revocation for machine identities so audit packs show lifecycle control, not just access logs.
- Align access reviews with NHI ownership Make every review confirm who owns the identity, what system depends on it, and whether the access scope still matches the current business need.
Bottom line: ISO 27001 maintenance can look disciplined while leaving non-human identities outside the core governance model.

ISO 27001 maintenance exposes an access governance gap, not just an audit burden: The article is strongest when it shows that certification is a living process of evidence, review, and remediation. That process can still leave NHI access outside the governance model if machine identities are not treated as auditable assets in their own right. The practitioner implication is that certification discipline must extend to service accounts, tokens, and certificates, or the ISMS will certify the wrong level of control.
A question worth separating out:
Q: Which ISO 27001 controls matter most for service account lifecycle management?
A: The most relevant controls are the ones that tie access permissions, evidence collection, and ongoing review together. For machine identities, that means governance over issuance, scope, monitoring, and retirement, with clear accountability for each identity. If those duties are split across teams, the lifecycle usually fails at the handoff points.
