What is PCI DSS?

The Payment Card Industry Data Security Standard (PCI DSS) is a cybersecurity standard founded and supported by leading credit card and payment processing companies. Its primary objective is to ensure the security of cardholder information.

PCI DSS applies to any entity that stores, processes or transmits cardholder data. Even if your business outsources all payment processing, you can still be held responsible by your acquirer or payment brand in the event of a data breach.

Protecting the world’s leading brands


PCI DSS compliance is mandatory for any organization that handles cardholder data. This includes:

  • Merchants that accept card payments for goods or services, regardless of whether they outsource payment processing
  • Service providers that directly handle cardholder data on behalf of other entities
  • Organizations that fulfil both roles

Yes, all businesses that are involved with payment processing need to comply with PCI DSS, regardless of their size or transaction volume. However, small merchants can reduce the amount of effort required to comply due to their simpler environments, limited cardholder data, and fewer systems to protect.

For example, eligible businesses can take a ‘Self-Assessment Questionnaire (SAQ) to assess their security and potentially reduce the scope of PCI DSS compliance as it related to their organization and environment.

It is not a legal requirement for businesses to be PCI DSS compliant. The standard is enforced via contracts between merchants, payment processers and payment providers.

Payment brands can penalize acquiring banks for PCI DSS violations. In addition, if merchants are non-compliant then acquiring banks can remove their ability to accept card payments. Fines can also be passed down to merchants, which can vary from $5,000 to $100,000 per month until the they achieve compliance.

If a PCI DSS data breach occurs then it is also highly likely that the EU GDPR (General Data Protection Regulation) may have also been breached in some form. This regulation levies its own fines of up to of up to €20 million or 4% of global annual turnover.

PCI DSS 4.0 is the latest version of the information security standard designed by the Payment Card Industry Security Standards Council (PCI SSC). V4.0 of the standard was released in March 2022 and supersedes the previous version, v3.2.1.

The PCI SSC defines PCI DSS as:

“The Payment Card Industry Data Security Standard (PCI DSS) was developed to encourage and enhance payment card account data security and facilitate the broad adoption of consistent data security measures globally. PCI DSS provides a baseline of technical and operational requirements designed to protect account data. While specifically designed to focus on environments with payment card account data, PCI DSS can also be used to protect against threats and secure other elements in the payment ecosystem.”

PCI DSS v4.0 will go into effect on 31st March 2024, at which point v3.2.1 will be retired and will no longer be an active version of the standard . However, organizations will have until 31st March 2025 to fully implement some of the new requirements that were initially defined as best practices in v4.0.

Given that PCI DSS v4.0 has over 300 sub-requirements, it is advised that organizations prepare for the transition as early as possible and define an implementation timeline to remain compliant.
