ISO/IEC 27001 and Penetration Testing
Selva Ops S.R.L.
ISO/IEC 27001 is a management-system standard. Certification audits look for a working Information Security Management System (ISMS): risk assessment, control selection, operation, and improvement — not a single product security ritual.
What the standard does not say
ISO/IEC 27001:2022 does not contain a clause that says “perform penetration testing every year.” Organizations that treat a PDF pentest as the ISMS will still fail if risk treatment, ownership, and continual improvement are missing.
Where penetration testing fits as evidence
In practice, independent testing often supports:
- Annex A 8.8 — management of technical vulnerabilities
- Annex A 8.29 — security testing in development and acceptance
- Broader risk treatment when your assessment identifies significant exposure in externally facing systems
Implementation guidance in ISO/IEC 27002 discusses technical vulnerability assessment approaches (including penetration testing as one option). Always map evidence back to your Statement of Applicability.
Auditor expectations
Expect questions about scope alignment with the ISMS boundary, how findings enter the risk register, remediation SLAs, and whether testing frequency matches residual risk — not marketing calendars.

FAQ
- Does ISO 27001 require an annual penetration test by name?
- No. ISO/IEC 27001:2022 does not mandate penetration testing as a named annual activity. Auditors often expect technical testing as evidence that selected Annex A controls operate effectively, based on your risk assessment and Statement of Applicability.
- Which Annex A controls does a pentest usually support?
- Commonly Annex A 8.8 (management of technical vulnerabilities) and 8.29 (security testing in development and acceptance). Your SoA decides what you claim; the pentest is evidence, not a substitute for the ISMS.
