Penetration Testing for PCI DSS Compliance - QSA-Aligned

If your organisation needs to carry out penetration testing as part of PCI DSS compliance, it’s essential that the testing meets the standard’s specific requirements.

Our experienced pentesters work closely with our in-house PCI DSS QSA team to ensure your testing is properly scoped, aligned to the standard, and documented for assessment, giving you confidence that your compliance needs are fully covered.

Why Penetration Testing Matters for PCI DSS

Image for pentesting for PCI Compliance service

PCI DSS explicitly requires penetration testing under Requirement 11.4: Annual and post-change testing for all systems in the CDE, covering both network and application layers, including segmentation controls.

Penetration testing supports a proactive approach by:

  • Identifying exploitable vulnerabilities
  • Validating defences before attackers do
  • Providing evidence of control effectiveness for assessors

Our PCI DSS-Aligned Penetration Testing Services

Securious delivers penetration testing services aligned to the latest PCI DSS v4.0.1 requirements, including:

  • External Penetration Testing - identifies vulnerabilities an attacker could exploit from outside your network.
  • Internal Penetration Testing - simulates a threat from inside your network or after perimeter defences are breached.
  • Segmentation Testing - validates that network segmentation is effectively isolating your CDE — critical for reducing PCI scope.
  • Web Application Testing - tests applications for vulnerabilities such as those in the OWASP Top 10, which could expose cardholder data.
  • Remediation Advice and Compliance Documentation - clear, actionable reporting and guidance to support your remediation and satisfy your QSA (including us, if we’re performing your assessment).
