QSA-Led PCI DSS v4.0.1 for UK Payments

Any UK organisation that handles payment-card data — merchants, fintechs, acquirers, PSPs and SaaS platforms — is required by the card brands and acquirers to demonstrate PCI DSS compliance. The current standard, PCI DSS v4.0.1, introduces stricter requirements around authentication, scripts, and continuous control validation.

CyberSigma's PCI QSA-led engagements take you from gap assessment to validated compliance — reducing scope where possible to cut cost and risk, and producing the SAQ or Report on Compliance (RoC) your acquirer requires.

• PCI DSS v4.0.1 gap assessment and readiness.
• Cardholder data discovery and scope reduction.
• SAQ guidance and Report on Compliance (RoC).
• Remediation support and compensating controls.
• Penetration testing and segmentation validation (Req. 11).
• Ongoing advisory for continuous compliance.

Why UK Payment Businesses Choose CyberSigma

As a PCI QSA (CEMEA) authorised firm, we deliver assessments recognised by acquirers and the card brands. We focus on practical scope reduction — tokenisation, segmentation and architecture changes — that lower both your assessment cost and your breach risk.

Our QSAs combine compliance rigour with real-world security testing, so you achieve genuine protection of cardholder data, not just a passing assessment.

Who needs PCI DSS compliance in the UK?

Any organisation that stores, processes or transmits payment-card data — merchants, fintechs, acquirers, payment service providers and SaaS platforms that touch cardholder data.

What is the difference between an SAQ and a Report on Compliance?

An SAQ (Self-Assessment Questionnaire) is for lower-volume merchants, while a Report on Compliance (RoC) is a QSA-conducted assessment required for higher transaction volumes (typically Level 1). We advise on which applies and deliver both.

What changed in PCI DSS v4.0.1?

v4.0.1 strengthens requirements around multi-factor authentication, payment-page script integrity, targeted risk analysis and continuous validation of controls. We help you meet the new and future-dated requirements.

Can you help reduce our PCI scope?

Yes. Through network segmentation, tokenisation and architecture changes we reduce the cardholder data environment, which lowers both your assessment effort and your risk.
