ISO 27001 Penetration Testing Services
ISO 27001 certification is built on evidence. A penetration test is some of the strongest evidence you can produce.
ISO 27001 doesn’t mandate penetration testing by name, but the standard’s approach to risk assessment and technical controls makes it the natural choice for organizations serious about certification. Annex A controls covering information security, access management, and vulnerability management all benefit from independent validation. A well-documented penetration test shows your auditor, your certification body, and your enterprise customers that the controls you’ve implemented have been tested against real-world attack techniques, not just documented in a policy.
The organizations pursuing ISO 27001 today are increasingly doing so because enterprise customers require it, particularly in European markets where the standard carries more weight than SOC 2. The certification signals something specific: that security is a managed program, not a checkbox. The pentest report is part of that signal.
What the Test Covers
ISO 27001 engagements follow the same methodology and deliver the same depth as any Asteros engagement. Web application testing grounded in the OWASP Application Security Verification Standard. External and internal network testing that maps exposure and lateral movement paths. Both, if your certification scope includes the full environment.
The report includes validated findings with proof of concept, an ASVS-based structured assessment for web application scope, remediation guidance written for your engineering team, and an executive summary suitable for your auditor, your certification body, and the enterprise procurement teams that will ask to see it. After remediation, a free retest validates the fixes and produces the closure evidence that demonstrates your vulnerability management process is real and operational, which is exactly what ISO 27001 auditors want to see.
Why the Report Structure Matters
ISO 27001 auditors and certification bodies want to see that risk identification is systematic and documented, that findings were prioritized and addressed, and that the process can be repeated. A scanner dump satisfies none of those requirements. A report that documents methodology, maps findings to risk ratings with business context, and includes a validated retest result satisfies all of them.
The same report also travels well. If you’re pursuing ISO 27001 because enterprise customers require it, the executive summary and attestation letter give you something to hand a procurement team without exposing technical detail.
SOC 2 and ISO 27001 Together
Many companies pursue both frameworks simultaneously or in sequence, particularly SaaS companies selling into both US and European enterprise markets. An Asteros engagement can support both. The report is structured to satisfy SOC 2 Trust Services Criteria and ISO 27001 Annex A controls from the same body of work. You don’t need two separate tests, and you don’t need two separate reports.
