What it covers

All 12 requirements of PCI DSS v4.0.1, with requirement numbers
CDE scoping and segmentation, including connected-to and security-impacting systems
SAQ selection (A, A-EP, B, B-IP, C, C-VT, P2PE, D), including the 2025 SAQ A script criterion
MFA, payment-page scripts (6.4.3 and 11.6.1), tokenization and hashed PAN
ROC and AOC preparation, compensating controls and the customized approach

Questions you can ask

“Which SAQ applies to an e-commerce site that uses a hosted payment page with our own scripts on the parent page?”
“Is a jump host that can reach the CDE in scope, and what does 1.3 and 1.4 require of it?”
“What changed between PCI DSS v4.0 and v4.0.1 for patching timelines?”

Every answer cites the PCI DSS requirement, article or control it rests on, so you can check it in seconds.

What you can upload for review

A network or data-flow diagram (Visio, draw.io or a screenshot) to check CDE scope and segmentation
Your information security policy, checked requirement by requirement
A risk register, checked against the targeted risk analysis requirements in 12.3

Files: PDF, Word, Excel or CSV, Visio (.vsdx), draw.io, or an image such as a screenshot. Choose a full review, a prioritized fix list (each gap with its fix and the evidence an assessor will expect) or a short summary, and download the result as Word or PDF.

What it’s built from

Compliance Colleague works from our own clause-referenced material, checked against: PCI DSS v4.0.1: Requirements and Testing Procedures (PCI Security Standards Council); PCI DSS v4.0.1 Self-Assessment Questionnaire A (SAQ A) (PCI Security Standards Council); PCI DSS v4.0.1 Self-Assessment Questionnaire A-EP (SAQ A-EP) (PCI Security Standards Council). It cites the clause so you can check it against your own copy.

Re-checked every month for new versions, deadlines and penalty changes. Full list on the sources page.
