Penetration Testing for ISO 27001 Certification

ISO 27001 requires organisations to test technical vulnerabilities as part of the Information Security Management System (ISMS). A professional penetration test is demonstrable evidence of compliance.

Why a pentest for ISO 27001?

ISO 27001 Annex A contains several controls related to technical security:

A.8.8 — Management of technical vulnerabilities
A.8.25 — Secure development
A.5.29 — Information security during disruption

An annual penetration test is the most direct way to demonstrate that you actively identify and manage vulnerabilities — a requirement nearly every ISO 27001 auditor expects.

What do we test?

Web applications and portals within the scope of the ISMS
External infrastructure (internet-facing systems)
Internal network segmentation and access management
API security and third-party integrations
Cloud configurations (Azure, AWS, GCP)

Auditor-ready reporting

Our report includes a risk overview that can be used directly as input for your ISMS risk register and Statement of Applicability. We also provide a management summary your auditor or certification body can review.

FAQ

How often do I need to run a pentest for ISO 27001?

ISO 27001 doesn’t prescribe a fixed frequency, but an annual pentest is the standard auditors expect. An interim test is recommended after significant changes to the environment.

Does a vulnerability scan also count as evidence for ISO 27001?

A vulnerability scan is a useful addition but doesn’t replace a penetration test. Auditors expect evidence of actively, manually tested vulnerabilities, not just automated scans.

Can you also help with the ISO 27001 implementation?

We advise on technical controls and vulnerability management as part of your ISMS, but a full ISO 27001 implementation falls outside our scope. We focus on the technical testing component.
