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 should vendor assessments be prioritised?
Prioritise suppliers according to service dependency, information sensitivity, system access and the consequences of failure. Use those factors to decide how much evidence and follow-up are needed. Record the reasoning so a critical service receives appropriate scrutiny while a low-risk supplier is not given an arbitrary identical questionnaire. Revisit the assessment when the service or access changes.
