If your business accepts card payments online, you need to consider the Payment Card Industry Data Security Standard (PCI DSS). This is a set of security requirements designed to protect cardholder data and reduce the risk of fraud. Simply put, if you process, store, or transmit credit or debit card information, you must meet certain standards to keep that data safe and maintain trust with your customers.
Why PCI DSS matters for UK SMEs
Failing to comply with PCI DSS can lead to serious consequences. Beyond potential fines from card schemes or your bank, a data breach involving card data can cause significant downtime, harm your reputation, and lead to loss of customers. For small and medium-sized businesses, this can be devastating. Compliance also helps you align with broader UK data protection laws such as the Data Protection Act 2018 and UK GDPR, which expect reasonable security measures around personal data.
A typical scenario: online retailer with 50 staff
Consider a UK online retailer with around 50 employees who uses a third-party payment gateway to take card payments on their website. While the payment gateway handles the card data, the retailer's website still collects some customer details and passes card information to the gateway. Without proper PCI DSS compliance, such as secure website design, regular vulnerability scans, and strong access controls, the retailer risks a breach that could expose cardholder data.
A good IT partner would help this retailer by:
- Confirming which parts of the payment process the retailer controls versus the payment provider
- Ensuring the website and any connected systems meet PCI DSS requirements, like using SSL/TLS encryption and secure coding practices
- Helping implement multi-factor authentication (MFA) for staff access to payment-related systems
- Advising on regular security scans and penetration testing to identify vulnerabilities
- Assisting with completing the appropriate PCI DSS Self-Assessment Questionnaire (SAQ) and preparing for any audits
Practical checklist for PCI DSS readiness
- Ask your IT provider: Do they understand PCI DSS requirements relevant to your business model? Can they help you complete the correct SAQ?
- Review your payment setup: Are you using a PCI DSS-compliant payment gateway or service? Who stores or processes card data?
- Check your website security: Is your site using HTTPS with a valid SSL certificate? Are software and plugins up to date?
- Access controls: Do you have strong password policies and MFA for all staff accessing payment systems?
- Logging and monitoring: Are access logs enabled and regularly reviewed for suspicious activity?
- Backups: Are backups of critical data performed regularly and stored securely, separate from live systems?
- Supplier management: Do you have documented security requirements for your payment providers and IT suppliers?
Meeting PCI DSS can seem complex, but breaking it down into manageable steps and working with knowledgeable IT professionals helps reduce risk and maintain customer confidence. If you take card payments online, it's wise to discuss your setup with a trusted managed IT provider or IT advisor who can guide you through compliance requirements and practical security measures tailored to your business.
