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 CR-CROSS-02. 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.
