What Is PCI DSS?

The Payment Card Industry Data Security Standard (PCI DSS) is an essential framework that any organization handling payment card data should follow to protect sensitive data. PCI DSS provides a comprehensive set of operational and technical requirements for safeguarding payment account data.

This post breaks down the PCI DSS meaning and importance, highlighting its key benefits for businesses. Additionally, we’ll discuss the different levels of PCI DSS compliance, helping organizations understand the specific requirements they must meet.

What does PCI DSS stand for? 

Let’s start with the PCI DSS definition. PCI DSS stands for the Payment Card Industry Data Security Standard. It was established in December 2004 by the founding members of the Payment Card Industry Security Standards Council in response to the growing need for a unified security standard to protect cardholder data amidst increasing online fraud and data breaches.

The core goal of PCI DSS is to encourage merchants worldwide to adopt consistent data security measures that protect cardholder data and ensure the secure processing, storage, and transmission of credit card information. Businesses can achieve these goals by meeting the technical and operational requirements outlined in the standard.

The importance of PCI DSS compliance

Why become PCI DSS compliant?

PCI DSS is more than just a set of requirements; it can be a valuable asset for organizations of any size. By meeting PCI DSS requirements, businesses can protect cardholder data and preserve the integrity of payment card transactions. Therefore, PCI DSS-compliant organizations can enhance their reputation, build customer trust, and prevent financial losses associated with data breaches.

Enhanced security. By adopting robust security controls and practices to meet PCI DSS requirements, you can identify and address vulnerabilities in your systems. As a result, your organization can become more resilient against cyber threats while you strengthen your overall security posture.

Operational efficiency. The benefits of compliance extend beyond security. Achieving PCI DSS compliance requires organizations to streamline their security practices and implement robust procedures, which can lead to improved operational efficiency. 

Customer trust. When clients know that your organization is PCI DSS compliant and you are handling their payment information securely, they are more likely to trust you. Hence, you benefit from increased customer loyalty and a stronger brand reputation.

PCI DSS requirements

The latest version, PCI DSS v4.0, consists of 12 requirements, each one containing a set of controls and procedures for organizations to implement to enhance their financial data security.

PCI DSS requirements address vulnerabilities and potential points of compromise within your systems. If you fail to comply with these requirements, you may be susceptible to cyberattacks that can lead to data breaches. 

If cardholder data is leaked, PCI regulators can impose fines and even forbid you from accepting payments or using your card payment systems. You also may face significant financial losses due to data breaches — costs related to data recovery, legal penalties, and compensation to affected parties. 

PCI compliance levels

What procedures should merchants follow? 

PCI DSS compliance is mandatory for all entities that process, store, or transmit credit card information or sensitive authentication data. This includes merchants, payment processors, financial facilities, and service providers that handle cardholder data. The requirements apply regardless of the organization’s size or the volume of transactions it handles.

Compliance is not a one-time event but a continuous process that requires regular monitoring, assessments, and updates to security practices. To achieve PCI DSS compliance, organizations need to implement all the requirements under PCI DSS, complete a yearly self-assessment questionnaire (SAQ), and pass quarterly PCI security scans. Some merchants also need to undergo an on-site PCI DSS audit that is performed by a Qualified Security Assessor (QSA).

Depending on the number of card transactions you process annually, your business falls into one of four PCI DSS compliance levels. The higher the level, the more rigorous your organization must be in auditing your compliance practices.

Take note that the major payment card brands (American Express, Discover, JCB, Mastercard, and Visa) may have their own thresholds for PCI DSS compliance levels. Also, those organizations that have suffered a cyber attack or data breach can be elevated to a higher level.

3 key steps of PCI DSS compliance

In general, the compliance process includes three steps:

1. Assessment. You must identify cardholder data, make an inventory of IT assets and business processes involved in payment card processing, and analyze them for potential vulnerabilities.
2. Remediation. You should fix vulnerabilities and address the risks to cardholder data.
3. Reporting. You must compile and submit the required compliance reports. As mentioned above, level 1 merchants are additionally subjected to an on-site PCI DSS audit by an authorized PCI QSA auditor.
