Are you ISO 27001 certified? How to answer it in a security questionnaire

Why buyers ask this

ISO 27001 is an internationally recognised certification of an information security management system.

What a strong answer includes

  • State whether you are certified, by which accredited certification body, scope and expiry.
  • If not certified, say whether you align to the standard and your plans.
  • Distinguish certification from 'alignment' clearly.

Sample answer to adapt

Replace the bracketed parts with your own facts. Only state what is true for your environment.

[Yes. Our ISMS is certified to ISO/IEC 27001:2022 by [certification body], certificate no. [X], scope [Y], valid until [date].] OR [We are not certified. Our controls are aligned to ISO 27001 Annex A, and certification is planned for [date].]

Evidence to attach

  • Scope document

Common mistakes

  • Claiming ISO compliance with no certificate.
  • Scope that excludes the product the customer is buying.
