ISO 27001:2022 Compliance Calendar — keep your ISMS certifiable

ISO 27001 certification doesn't end at the Stage 2 audit — Clauses 9 and 10 require an ongoing operating ISMS with documented monitoring, internal audit, management review, and continual improvement. Skip them and you'll find out at the Year-1 surveillance.

FAQ

How often does ISO 27001:2022 require management review?
At planned intervals — interpreted in practice as at least annually. Clause 9.3.2 sets a fixed agenda; deviating from it is a frequent finding.
Can the same person run internal audit and own ISMS controls?
No — Clause 9.2.2(c) requires auditor independence from the activity audited. Use a different internal team member, a peer ISMS, or an outsourced internal auditor.
Do we have to follow this calendar exactly to stay certified?
The cadences here reflect industry practice. Your ISMS may schedule items more frequently if risk-driven, but skipping any of clauses 9.1–10.1 is a non-conformity.
What changed for ongoing cadence with ISO 27001:2022?
Annex A reorganised to 93 controls in 4 themes. Notably 5.7 (threat intelligence), 5.30 (ICT readiness), 8.9 (configuration mgmt), 8.16 (monitoring activities), and 8.23 (web filtering) require explicit ongoing operation — they're often missed by teams transitioning from :2013.
