What is PCI DSS?

The Payment Card Industry Data Security Standard (PCI DSS) is a set of mandatory requirements designed to safeguard cardholder data. PCI DSS compliance is mandatory for any business that processes credit and debit card transactions and vital for companies that want to keep their customers’ data secure.

Each transaction your business processes will involve sensitive cardholder information. This data must be processed, stored and transmitted securely to protect your customers and your business from the increasing threat of fraud.

Benefits of PCI DSS compliance

Build trust

Achieving PCI DSS compliance shows your company is dedicated to keeping your customers’ valuable information safe and secure and out of the hands of fraudsters.

Protect reputation

Complying with PCI DSS requirements means avoiding a wide range of financial and reputational costs that can arise from non-compliance.

Meet customer expectations

As customers become increasingly aware of how important it is to know their financial and personal data is safe, you are less likely to lose them to a competitor if they know their data is your priority.

 

The global standard

PCI DSS consists of 12 high-level requirements across six categories. Some or all the 12 may be applicable to you depending on the nature of your business, and whether you store card data or not.

Compliance with PCI DSS is mandated by all the Card Schemes (including Visa® and Mastercard®) and applies to all businesses that accept credit and debit cards. A global forum – the PCI Security Standards Council – oversees the standard. The council released the latest update (version 4.0) on 31/3/22. PCI DSS v3.2.1 remains valid until 31/3/24.

How to become compliant

Businesses need to validate their compliance on an annual basis and are expected to maintain compliance at all times.

For small or medium-sized businesses you must either complete a PCI DSS Self-assessment Questionnaire (SAQ) or have a Formal Onsite Assessment by a Qualified Security Assessor(QSA) to demonstrate compliance.

For larger or more complex businesses, the PCI Security Standards Council website provides a list of approved QSAs who can work with you to ensure that your business is PCI DSS compliant.

If you are a small or medium-sized business, we require you to report your PCI DSS compliance using the Cardnet Merchant PCI Portal. There are three options:

1. Self-assessment:

Complete your own Self-Assessment Questionnaire (SAQ) available for download from the PCI Council website then upload your compliant SAQ or third-party certificate from a QSA onto our PCI DSS online portal. Cardnet does not charge a fee for this.

Instructions on how to access the portal will be provided once your Cardnet account has been opened.

2. Assisted online reporting service:

Manage, report and maintain your compliance using our online service at www.lloydsbankcardnetpcidss.com. It provides assistance and information to help you to understand which requirements are appropriate to your business and guides you through your Self-Assessment Questionnaire (SAQ) step by step.

It’s an ongoing service with a monthly management fee of £5.00 + VAT and offers

  • Access to the PCI Helpline and online chat
  • Task and revalidation reminders
  • Information Security Policy template
  • ‘Security Measures for Your Business’ checklist

Using third-party service providers

In addition to becoming compliant yourself, if you use a third party to store, process or transmit payment card data on your behalf, you should also consider the following:

  • Clearly identify the services and system components included in the scope of the service provider’s annual onsite PCI DSS assessment.
  • Identify the specific PCI DSS requirements covered by the service provider, and any requirements that are the responsibility of their customers, to include in their own PCI DSS reviews.
  • Provide evidence that the checks covered the services of relevance to the customer and that the necessary PCI DSS requirements were determined to be in place if a third party undergoes their own PCI DSS assessment.

Any contract you have with a third party should require the other party to comply with PCI DSS. If a third party does not provide evidence of compliance, then that company’s relevant systems or processes may need to form part of your own compliance annual review. This could lead to remediation if vulnerabilities are discovered.

Third parties include:

  • Software providers
  • Payment service providers
  • Web-hosting companies
  • Electronic point of sale (EPoS) solutions
  • Till vendors

Using a hosted payment solution

If you decide to use a Hosted Payment Page (HPP) to process e-commerce transactions, the most secure approach is to outsource your card data to a payment service provider. This allows you to keep the data totally segregated from your e-commerce environment at all times. 

Even with this arrangement, you should use ‘penetration testing’ which can verify that the data doesn’t enter your business’s environment, giving you peace of mind that your customers’ data is safe.
