PCI DSS<\/a> isn\u2019t just a technical standard. It\u2019s a business-critical framework that helps protect your organisation, and your customers, from the serious risks tied to handling cardholder data. But despite being a well-established standard, many UK businesses still find PCI DSS confusing, overly complex, or just plain hard to keep on top of.<\/p>\n\n\n\n

Whether you’re working through your first Self-Assessment Questionnaire (SAQ)<\/a>, integrating with new payment platforms, or prepping for your next audit, the same key questions come up again and again.<\/p>\n\n\n\n

In this blog, we\u2019ve answered the most common PCI DSS compliance questions in plain English. No jargon, no unnecessary complexity. Just what you need to know to stay secure, avoid fines, and remain audit ready.<\/p>\n\n\n\n

PCI DSS Frequently Asked Questions<\/h2>\n\n\n\n
<\/div>\n\n\n\n

1. Does PCI DSS apply if we don\u2019t store cardholder data?<\/strong><\/h4>\n\n\n\n

Yes, and this is one of the most misunderstood points about PCI DSS.<\/p>\n\n\n\n

Even if you never store cardholder data, the moment you process or transmit it, or may otherwise impact the security of cardholder data, you\u2019re in scope. For example, if you operate an ecommerce site that uses Stripe, Shopify, or another payment gateway, your website may still handle sensitive card data before it’s passed off to the provider. That still counts and PCI DSS requirements still apply.<\/p>\n\n\n\n

Why this matters:<\/strong>
Many organisations assume they\u2019re exempt because they \u201cdon\u2019t keep anything,\u201d but PCI DSS applies to the entire transaction journey, and anything that could impact the security of that journey, not just the storage of cardholder data.<\/p>\n\n\n\n

What to do:<\/strong>
Always carry out a formal scoping exercise to understand how and where cardholder data flows through your systems even if only briefly, or if you can impact the security of cardholder data in other ways (e.g. if you provide a managed service).<\/p>\n\n\n\n

2. Is vulnerability scanning enough to meet PCI DSS testing requirements?<\/strong><\/h4>\n\n\n\n

Not on its own. Vulnerability scanning may be applicable to you, but it\u2019s only one piece of the puzzle.<\/p>\n\n\n\n

PCI DSS Requirement 11<\/a> calls for both automated vulnerability scans and manual penetration testing. Scans are great for catching obvious or known issues, like missing security patches, but they won\u2019t show you how those issues could be chained together by a real attacker.<\/p>\n\n\n\n

Penetration testing simulates actual attacks, going beyond what a tool can do. It helps uncover logic flaws, access control weaknesses, or system misconfigurations that wouldn\u2019t show up in a scan.<\/p>\n\n\n\n

Pro tip:<\/strong>
Use a CREST<\/a> or CHECK<\/a>-accredited testing provider (like 3B Data Security) to ensure your testing meets PCI expectations and gives you actionable results.<\/p>\n\n\n\n

<\/div>\n\n\n\n

3. Do we really need written policies for PCI DSS compliance?<\/strong><\/h4>\n\n\n\n

Yes, and they\u2019re more important than most people realise.<\/p>\n\n\n\n

You might have strong technical controls, but if they\u2019re not backed by clear, written policies and procedures, you\u2019ll still fall short in a PCI audit. Documentation helps ensure that security practices are repeatable, reviewable, and enforceable, not just ad hoc.<\/p>\n\n\n\n
