SCOPE & APPLICABILITY

Who Does PCI DSS Apply To?

PCI DSS applies to any organisation that stores, processes, or transmits payment card data — or that could affect the security of cardholder data.

MERCHANTS

Merchants Accepting Card Payments

Any business accepting Visa, Mastercard, or other payment scheme cards must comply — from sole traders using a card reader to large e-commerce retailers processing millions of transactions.

SERVICE PROVIDERS

Service Providers

Technology companies, payment processors, hosting providers, and SaaS platforms that store, process, or transmit cardholder data on behalf of merchants.

SCOPE REDUCTION

Reducing Your Scope

Using a fully hosted payment page or tokenisation can dramatically reduce what PCI DSS applies to in your environment. We help you understand your current scope — and whether there are sensible ways to shrink it.

v4.0.1

PCI DSS v4.0.1

PCI DSS v4.0.1 is the current version. The transition from v3.2.1 was required by 31 March 2025. New future-dated requirements became mandatory from 31 March 2025. We assess your environment against the current version.

KEWDATA SERVICES

Our PCI DSS Compliance Services

We support merchants and service providers from first assessment through to SAQ completion, remediation, and privacy alignment.

01

Gap Assessment

A review of your cardholder data environment against PCI DSS v4.0.1 requirements — identifying what you meet, what you need to fix, and what controls are missing.

02

SAQ Completion Support

We work with you to select the right SAQ type for your environment, gather the evidence needed for each requirement, and complete the self-assessment questionnaire accurately.

03

Scope Definition

Defining your cardholder data environment (CDE) accurately — including connected systems, cloud environments, and third-party integrations — so your compliance efforts focus on the right place.

04

Remediation Planning

A prioritised plan to close the gaps found in the assessment — with clear ownership, timelines, and guidance on the most cost-effective way to reach compliance.

05

Privacy and GDPR Alignment

Card data is personal data under UK GDPR. We align your PCI DSS controls with your GDPR obligations — covering retention, security, and breach notification requirements under both frameworks.

06

Ongoing Compliance Support

Annual reassessment support, policy maintenance, and tracking of PCI Security Standards Council guidance — keeping your compliance current as your payment environment evolves.

SAQ TYPES

Which SAQ Type Applies to You?

PCI DSS self-assessment questionnaires differ depending on how you take card payments. Using the wrong one is a compliance risk.
