ISO 27001 penetration testing requirements: what auditors actually look for

B9ITS VAPT Practice 12 Mar 2026 11 min read Intermediate

ISO/IEC 27001:2022 has 93 Annex A controls and not one of them says the words "penetration testing". Yet every Stage 2 audit asks for VAPT evidence. Here is exactly which controls auditors map it to, and the four documents you need on file.

The three relevant controls

A.8.8 — Management of technical vulnerabilities

The text requires the organisation to obtain timely information about vulnerabilities, evaluate exposure, and take action. The implementation guidance — and ISO 27002:2022 makes this explicit — names penetration testing among the techniques to identify exposures. Stage 2 auditors universally expect a VAPT report or equivalent as the evidence artifact.

A.8.29 — Security testing in development and acceptance

Requires security testing in the development lifecycle. For SDLC organisations this maps to SAST, DAST, and a pre-release pen test of significant features. The auditor will ask for the test report from the most recent release.

A.5.35 — Independent review of information security

An independent third-party review. A vendor-conducted VAPT — by a firm not on the audited organisation's payroll — is the canonical artifact. This is the control that prevents internal-team-only testing.

The four documents on file

  1. Pen test policy. One page. Specifies scope, frequency (annual + on significant change), authorisation, and rules of engagement. References A.8.8 and A.8.29 directly.
  2. Most recent VAPT report. Dated within the audit window (typically 12 months). Engineer-written, with reproducible findings.
  3. Remediation plan. Each Critical/High finding mapped to a fix, an owner, and a target date.
  4. Re-test attestation. Confirmation that the Critical/High findings have been fixed and verified. The free re-test we include exists for this artifact.

Common Stage 2 audit findings

Cadence

The minimum auditor expectation is annual. The mature posture is annual + on significant change — where "significant change" means a new module, an architectural change, or a major framework upgrade. For DevOps shops we recommend a continuous component (scanner + SAST in CI) plus the annual deep VAPT.

Scope of the test

Match it to the ISMS scope. If the ISMS covers "the production environment of the customer-facing application", the VAPT should cover the customer-facing application. Internal corporate IT is in scope only if the ISMS includes it. Office Wi-Fi and laptops are rarely needed unless your ISMS explicitly lists them.

What B9ITS provides

Our VAPT report ships with an ISO 27001 mapping appendix that lists each Annex A control addressed and which finding contributes evidence. Stage 2 auditors recognise the format and accept it without back-and-forth.

For the methodology, see our approach. For the broader compliance topic, see VAPT for RBI-regulated entities if you are also in BFSI.
