The Payment Card Industry Data Security Standard is mandatory for any organisation that stores, processes, or transmits cardholder data. Non-compliance can result in fines of £10,000–£100,000 per month and the loss of card processing rights.
PCI DSS v4.0 — effective since March 2024 — is organised around 12 requirements covering network security, cardholder data protection, vulnerability management, access control, monitoring, and policy. Compliance is validated annually via a Self-Assessment Questionnaire (SAQ) or a QSA-led Report on Compliance, plus quarterly ASV vulnerability scans.
P2P CyberDefence makes PCI DSS practical: correct scoping, accurate SAQs, genuine scope reduction, and an evidence cycle that runs all year rather than a last-minute scramble.
"Correct network segmentation can dramatically reduce your PCI scope — and with it, the cost and burden of compliance. Most businesses are over-scoped."Scope review firstOften the highest-value step in PCI engagements
A cardholder data breach triggers fines from Visa and Mastercard and potential loss of processing rights. PCI controls reduce breach probability and limit financial exposure.
Choosing the wrong SAQ type — or answering inaccurately — creates compliance gaps. We determine the correct SAQ for your environment and complete it with you.
A flat network puts everything in PCI scope. We design and validate segmentation that genuinely reduces scope, cost, and audit burden.
Unclear whether your payment provider setup reduces scope? We assess your payment architecture and advise on real scope-reduction strategies.
ASV scans, remediation, and evidence collection are easy to miss. We coordinate the full quarterly cycle on your behalf.
We build continuous compliance processes so evidence is gathered throughout the year — not in a panic before the deadline.
Map cardholder data flows, define the CDE boundary, and validate segmentation controls that reduce compliance scope.
Accurate completion of SAQ A, A-EP, B, C, C-VT, and D with supporting evidence for every control.
Quarterly Approved Scanning Vendor scans managed end-to-end — triage, remediation coordination, and clean submission.
Annual internal and external pen tests of the CDE as required by Requirement 11.4, with formal compliance reporting.
Gap analysis against every applicable requirement with prioritised, risk-ranked findings and effort estimates.
Preparation for Qualified Security Assessor engagement — evidence management, query resolution, and assessment support.
