How do I know if I'm PCI compliant?
Start with your acquirer. Many show your validation status in their PCI compliance portal, and a monthly non-compliance fee on your statement usually means they hold no current SAQ or Attestation of Compliance for you. Worldpay merchants, for example, validate through its SaferPayments portal, as our guide to Worldpay PCI compliance explains. Then check the substance: work out which SAQ or Report on Compliance applies to you and confirm that every requirement in it is in place, with evidence.
The PCI compliance checker above does the second part in about five minutes. For the detail behind each answer, our PCI DSS compliance checklist covers all 12 requirements with the evidence a QSA will ask for.
Is PCI compliance a legal requirement in the UK? No. It is a contractual requirement that your acquirer sets in your merchant agreement, and our guide to PCI compliance in the UK explains what that means for you.
What is a PCI compliance test?
PCI compliance testing can mean a readiness check like this one, a quarterly external scan by an Approved Scanning Vendor (ASV) or a penetration test. There is no single official PCI compliance test, and none of the three makes you compliant on its own.
| What "PCI compliance test" can mean | What it checks | Who carries it out | Does it confirm compliance? |
|---|---|---|---|
| Readiness self-check (this page) | Your answers against the core of each of the 12 requirements, and your likely SAQ | You, in about five minutes | No, it shows your gaps |
| ASV scan | Internet-facing systems for known vulnerabilities, every quarter (Requirement 11.3.2) | A PCI SSC Approved Scanning Vendor; ours are delivered through our PCI SSC Approved Scanning Vendor partner | No, it meets one requirement |
| PCI penetration test | Whether weaknesses can be exploited, and whether segmentation works (Requirement 11.4) | A qualified, organisationally independent internal resource or third party | No, it meets one requirement |
Compliance itself is confirmed only by validating against the whole standard: a Self-Assessment Questionnaire with an Attestation of Compliance for organisations allowed to self-assess, or a Report on Compliance, usually from a QSA. Use the check to find your gaps, the scans and tests to meet Requirements 11.3 and 11.4, and the SAQ or ROC to prove the rest.
Is a PCI scan the same as PCI compliance?
No. A passing quarterly ASV scan satisfies Requirement 11.3.2 and nothing else, so you still need every other requirement in your SAQ or ROC. Our PCI ASV scanning is delivered through our PCI SSC Approved Scanning Vendor partner, and you can check any scanning company against the PCI SSC's official list of Approved Scanning Vendors.
How is the readiness score worked out?
PCI DSS has no pass mark: every requirement that applies to you must be in place. The score shows how close you are. Critical gaps count three times, high-impact gaps twice and the rest once. "No" and "Unsure" both score zero, because an assessor can only accept what you can evidence, and "Not applicable" answers are left out.
| Your result | What it means | Suggested next step |
|---|---|---|
| 100% | No gaps found in the core requirements | Complete your SAQ, or book a QSA assessment if you need a Report on Compliance |
| 80% to 99% with no critical gaps | Close to ready | Fix the remaining items and gather evidence, then validate |
| 50% to 79%, or any critical gap | Significant gaps | A gap analysis and a prioritised remediation plan |
| Below 50% | Not ready yet | Confirm your scope and SAQ first, then a gap analysis with our PCI DSS consultancy team |
What should you do after the check?
- Fix critical gaps first: sensitive authentication data, quarterly ASV scans and payment page scripts.
- Confirm your SAQ with our guide to which PCI SAQ you need, reading the eligibility criteria in the SAQ itself.
- Work through your fix list and collect evidence for each requirement as you go.
- Book scans and testing early, because a failed scan or test needs fixing and retesting before you can validate.
- Validate: sign your SAQ and Attestation of Compliance, or book a QSA assessment if your acquirer or customers require one.
Do you need PCI compliance software?
Not always. PCI compliance software helps you organise the work, and for a business with several payment channels or a long SAQ it can save time, but it does not make you compliant and it cannot do the parts of PCI DSS that need an independent assessor or tester. A small merchant on a short SAQ can often manage with the acquirer's portal, the free SAQ and a free way to check PCI compliance readiness, such as the tool on this page.
| What PCI compliance software does | What it cannot do |
|---|---|
| Policy templates you adapt to your business | Choose the right SAQ for you: it can only apply the answers you give it, and a wrong answer about how payments flow puts you on the wrong SAQ |
| Evidence collection, with owners and reminders when evidence goes out of date | Sign a Report on Compliance, which only a QSA (or an ISA where the card brand allows it) can do |
| Scan scheduling and tracking of ASV results | Replace the QSA that Level 1 merchants and Level 1 service providers need for their annual ROC |
| SAQ workflow: questions, responsibilities and sign-off | Test segmentation, which Requirement 11.4.5 gives to a qualified, organisationally independent tester |
Before you buy, check which SAQs and requirements the product covers, and whether it runs external scans or only schedules them: the quarterly scans must still come from a PCI SSC Approved Scanning Vendor. Our guide to PCI compliance cost shows where software and tooling sit among your other costs.
Can I do PCI compliance myself? Usually yes, and our guide to PCI compliance in the UK explains when you can and when you cannot. If you would rather have a person than a platform, our PCI DSS consultancy team confirms your scope and SAQ and builds the remediation plan with you.
