What this page covers

Practical guidance for ISO 27001: scope, risk, controls, and evidence that matches how your organisation really works. Use the takeaways and FAQ below as a checklist; then deep-link into your registers and change records.

Practical next steps

Assign owners, set review dates, and collect artefacts that match production reality. Use internal audits to rehearse the story before the external certification audit.

Common pitfalls

Avoid scope drift, ownerless actions, and documentation that does not match live configuration. Prefer short maintained records over one-off project dumps.

Key takeaways

  • Link controls to risk treatment and your Statement of Applicability, avoid policy-only boxes.
  • Assign owners, review cadence, and measurable acceptance criteria for every material action.
  • Use sampling and KPIs to show controls work in operations, not only that they were planned.
  • Align incidents and vendor changes with privacy/legal where personal data or chain risk is involved.

Frequently asked questions

How is a readiness assessment different from certification?
A readiness assessment identifies gaps against a chosen scope and criteria to help plan further work. It is not the external certification decision. Record what was examined, what evidence was available and where uncertainty remains. Use the findings to assign actions and confirm completion rather than presenting a preliminary score as proof that a certificate will be issued.
