How do I make sure our payment systems meet PCI DSS standards?

Updated

Ensuring your payment systems comply with PCI DSS (Payment Card Industry Data Security Standard) means protecting your customers' card data and meeting industry rules designed to reduce fraud and data breaches. For UK small businesses and SMEs that accept card payments—whether in-store, online, or over the phone—this is essential to avoid costly fines, reputational damage, and operational disruption.

Non-compliance can lead to serious consequences such as payment provider penalties, increased risk of cyberattacks, and loss of customer trust. For example, if your payment system is compromised, you could face downtime while investigating and fixing the breach, which impacts sales and staff productivity. Additionally, you may need to notify the Information Commissioner's Office (ICO) under UK GDPR and Data Protection Act 2018 if personal payment data is exposed.

Typical SME scenario

Consider a UK retailer with around 50 staff who recently expanded to online sales. They use a mix of card terminals in-store and a third-party payment gateway online. Without a clear PCI DSS compliance plan, they risk gaps such as outdated software on payment devices, weak access controls, or unencrypted data transmissions. A trusted IT partner would first assess their current environment, identify vulnerabilities, and then help implement controls like network segmentation, multi-factor authentication (MFA), and regular security testing to meet PCI DSS requirements.

Practical checklist for PCI DSS readiness

  • Ask your IT provider: Do they have experience with PCI DSS compliance? Can they provide evidence of past projects or certifications?
  • Review your payment environment: Identify all systems that store, process, or transmit cardholder data, including terminals, servers, and cloud services.
  • Access control: Check that only authorised staff can access payment systems and that strong passwords and MFA are enforced.
  • Network security: Ensure payment data is isolated from other parts of your network to reduce risk.
  • Software updates: Confirm all payment devices and software are regularly patched and updated to fix security vulnerabilities.
  • Logging and monitoring: Verify that access and transaction logs are kept securely and reviewed regularly for suspicious activity.
  • Data encryption: Make sure cardholder data is encrypted both in transit and at rest.
  • Backup procedures: Ensure payment data backups are performed securely and tested for restoration.
  • Supplier management: Include PCI DSS compliance requirements in contracts and questionnaires when working with third-party payment providers or IT services.

Next steps

Meeting PCI DSS standards can seem complex, but working with a managed IT provider experienced in UK payment security can simplify the process. They can help you identify risks, implement the necessary technical and procedural controls, and prepare for any audits or assessments. Start by discussing your current payment setup and compliance concerns with a trusted IT advisor who understands the practical needs of UK SMEs.
