This Service Covers

PCI DSSRequirements 1–6 — Network security, system hardening, encryption, access
ISO 27001Annex A 8.20–8.22 — Network security

What You Get

Technical security audit of your payment processing infrastructure. We assess: network architecture and segmentation (Req.1), system hardening and default configurations (Req.2), cardholder data encryption at rest (Req.3), encryption in transit (Req.4), malware protection (Req.5), and secure development practices (Req.6). Result: detailed findings report with risk levels, PCI DSS reference, remediation guidance, and a payment data flow diagram showing where cardholder data exists in your environment.

Optimum Web provides audit preparation, documentation and technical verification. We are not a certification body, we do not employ auditors, and we do not perform internal or certification audits. The Clause 9.2 internal audit is conducted by a person independent of the area audited within your organisation, or by an auditor you appoint; the certification audit is conducted by an accredited certification body. Our role is to make sure you are ready for both.

Who Needs This

  • E-commerce companies processing payments through their own infrastructure
  • Organizations preparing for PCI DSS SAQ D or ROC assessment
  • Businesses that had a payment-related security incident

Frequently Asked Questions

What is the 'cardholder data environment' (CDE)?+
All systems, networks, and processes that store, process, or transmit cardholder data, plus systems connected to them. Defining the CDE boundaries is the first step — everything inside must comply with PCI DSS.
We use Stripe — do we still need this?+
If you use Stripe Elements/Checkout (card data never touches your servers): likely not, SAQ A is sufficient. If you handle card data server-side: yes. The audit determines what's actually in your CDE.
What is network segmentation and why does it matter?+
Segmentation isolates the CDE from other networks. Without it, your entire network is in PCI scope. Proper segmentation reduces scope, cost, and risk. We assess current segmentation and recommend improvements.
Do you test for actual vulnerabilities?+
This audit assesses architecture, configuration, and compliance — not active exploitation. For penetration testing, see /security/penetration-testing/. Both together provide complete PCI security validation.
Can this be combined with the SAQ (CR-PCI-01)?+
Yes, and we recommend it. This audit provides the technical evidence for SAQ requirements 1-6. The SAQ (CR-PCI-01) covers the remaining requirements and produces the submission-ready document.
