Trace the payment flow
We document how card data enters, moves through and leaves the organisation across websites, terminals, people, suppliers and systems.
Payment account security
PCI DSS readiness support in Wrexham
If your organisation stores, processes or transmits payment account data, PCI DSS sets a baseline of technical and operational requirements for protecting it. We help identify the real payment environment, reduce unnecessary scope and prepare the controls and evidence for the validation route agreed with your acquirer or payment partners.

Scope first
The payment journey determines the work
A hosted online checkout, standalone payment terminal, integrated till and service provider environment can have very different PCI DSS responsibilities. Assuming that a payment supplier handles everything can leave connected systems, people or processes overlooked.
We map payment channels and third parties before selecting controls or questionnaires, then identify safe opportunities to reduce the cardholder data environment.
- Where payment account data is entered, stored, transmitted or viewed
- Which systems can connect to or affect the payment environment
- Which responsibilities sit with payment and technology suppliers
- Which validation route has been requested by the acquirer or card brand
Current requirements
Prepare technical and operational evidence together
PCI DSS v4.0.1 combines secure network design, system configuration, account-data protection, vulnerability management, access control, monitoring, testing and security policy. The controls need evidence that they operate consistently, not only screenshots collected at submission time.
We can help remediate the IT environment and coordinate evidence owners while leaving formal assessment decisions to the appropriate validation body.
Shared responsibility
Third-party payment services reduce work, not accountability
Outsourcing payments can significantly reduce scope, but merchants and service providers still need to understand their own responsibilities, keep agreements and attestations current, and manage systems that could affect payment security.
A clear responsibility map helps prevent gaps between your organisation, website provider, payment processor, managed IT provider and assessor.
Simple process
From problem to practical plan
Reduce and protect the scope
Architecture and controls are reviewed to remove avoidable exposure and close gaps in the applicable PCI DSS requirements.
Prepare the validation
Evidence is organised for the SAQ, attestation or independent assessment route confirmed with your acquirer or Qualified Security Assessor.
Independent decisions stay independent
Preparation you can stand behind.
Wrexham Tech Support is not a PCI Qualified Security Assessor and does not determine an organisation's compliance status. Validation requirements should be confirmed with the relevant acquirer, payment brand or QSA.

Before you get in touch
Still unsure? A quick message is enough—we will point you in the right direction.
Does PCI DSS apply if we use a third-party payment provider?
It can. Outsourcing payment processing may reduce your scope, but your organisation normally retains responsibilities for its payment channels, connected systems, suppliers and validation. Confirm the exact route with your acquirer.
Which PCI DSS questionnaire do we need?
The appropriate SAQ depends on how payments are accepted and how cardholder data is handled. We can document the environment, but the final validation route should be confirmed with your acquirer or QSA.
Are you a PCI Qualified Security Assessor?
No. We provide scoping support, gap analysis, technical remediation and evidence preparation. Where a QSA assessment is required, we can work alongside the appointed assessor.
Can Cyber Essentials replace PCI DSS?
No. Cyber Essentials is a useful general technical baseline, but PCI DSS has specific requirements for payment account data and its environment. Controls may overlap, but the obligations are not interchangeable.
