ISO 27001 penetration testing
ISO 27001 asks you to manage technical vulnerabilities and to test security functionality. This engagement produces the evidence for both, mapped to the Annex A controls your certification body will ask about.
Which controls this supports
In the 2022 revision of ISO/IEC 27001, the relevant Annex A controls are 8.8 Management of technical vulnerabilities, 8.29 Security testing in development and acceptance, and 8.9 Configuration management. Penetration testing is the most direct evidence auditors accept for 8.8 and 8.29.
Certification bodies look for more than the existence of a report. They want to see that testing is part of a repeatable process: that scope is justified, that findings feed into your risk treatment plan, that remediation is tracked to completion, and that the cycle repeats. A one-off report with no follow-through tends to generate a nonconformity rather than close one.
Our reports are structured with that in mind — every finding carries a severity, an owner-ready remediation action and a retest status, so it can be dropped straight into your risk register and your Statement of Applicability evidence without being rewritten.
What you receive for the audit
- Signed attestation letter with scope, methodology, dates and outcome
- Findings mapped to Annex A 8.8, 8.29 and 8.9 where applicable
- Severity ratings that drop directly into your risk treatment plan
- Executive summary for management review
- Technical report with reproducible evidence for each finding
- Free retest within 90 days, reissued showing verified remediation
- Support for auditor questions during certification and surveillance
- A documented, repeatable scope you can re-run next cycle
FAQ
Questions about this service
Is penetration testing mandatory for ISO 27001?
The standard does not name it as mandatory. Annex A 8.8 and 8.29 require you to manage technical vulnerabilities and to test security functionality, and penetration testing is the evidence most certification bodies expect to see for those controls.
How does this fit our surveillance audits?
Certification runs on a three-year cycle with annual surveillance audits. Most organisations test annually so that each surveillance visit has current evidence, and re-scope after any significant change to the ISMS boundary.
Can you map findings to our risk register?
Yes. Findings are delivered with severity, impact and remediation in a form that transfers into a risk treatment plan without rewriting, and we will match your register's field names on request.
