What Is PCI Compliance?

Payment card industry (PCI) compliance is a set of standards and regulations established by credit card companies to safeguard credit card transactions within the payments industry. It revolves around the technical and operational requirements that businesses must adhere to in order to secure and protect credit card data transmitted during card processing.

These standards are developed and overseen by the PCI Security Standards Council, an organization dedicated to maintaining the security of credit card information. Companies that conform to these standards are considered PCI compliant.

Understanding PCI Compliance

Although PCI compliance isn't a legal requirement, it has gained mandatory status through court precedent and is integral to ensuring the security of credit card processing. The Federal Trade Commission (FTC) oversees credit card processing, emphasizing the need for consumer protection and oversight.

PCI compliance forms a fundamental component of any credit card company's security protocol and is typically mandated by credit card companies, detailed in credit card network agreements. Besides the PCI Security Standards Council, other significant entities involved in setting standards for the credit card industry include The Card Association Network and the National Automated Clearing House (NACHA).

Requirements for PCI Compliance

PCI compliance standards place an onus on merchants and businesses to handle credit card data securely. Failure to do so can lead to breaches that compromise sensitive financial information and can be used for fraudulent purposes, including identity theft. Compliance involves adhering to guidelines established by the PCI Security Standards Council through the Payment Card Industry Data Security Standards (PCI DSS), which comprises 12 key requirements, 78 base requirements, and over 400 test procedures.

These requirements encompass a range of security measures, including the use of firewalls, robust password protection (such as two-factor authentication), encryption of transmitted cardholder data, antivirus and anti-malware software, regular software updates, access restriction, unique IDs for data access, physical data storage security, access log creation and monitoring, routine security system testing, and documented policy creation.

The most recent version of PCI DSS, version 4.0, was released in March 2022, underscoring the need for credit card processors to continually follow these security steps by assessing their networks and systems, IT infrastructure, business processes, and credit card handling procedures.

Benefits of PCI Compliance

The advantages of PCI compliance are multifold. It reduces the risk of data breaches, safeguards cardholder data, and mitigates the potential for identity theft. Being compliant also minimizes fines related to data breaches, enhances a company's reputation, and fosters customer trust, which leads to brand loyalty. In a world where 95% of cybersecurity breaches are caused by human error, protecting cardholder data is both ethical and good business practice.

In the first half of 2020, 36 billion records were exposed through data breaches, with 86% of them financially motivated. With the global information security market expected to reach $170 billion, the financial risk of non-compliance is substantial. Ensuring that sensitive information remains secure not only protects businesses but also prevents individuals from suffering financial loss.

Drawbacks of Being PCI Non-Compliant

Non-compliance with PCI standards carries severe consequences. Besides the increased risk of data breaches, businesses can face fines, penalties, and a loss of ability to process credit card data in the future. Financial institutions and payment companies may refuse to do business with non-compliant entities, leading to lost sales and a damaged brand image.

Fines for non-compliance can range from $5,000 to a staggering $500,000 per PCI data security incident or breach. Furthermore, notifying all individuals whose information may have been compromised is required to protect them from fraudulent charges.

Examples of PCI Compliance and Data Breaches

PCI compliance is an essential tool for preventing fraudulent activities and mitigating data breaches. The annual "Verizon Payment Security Report" highlights the state of PCI DSS compliance, emphasizing the importance of adhering to these standards. Notably, 36.7% of organizations actively maintained PCI DSS programs in 2018. The Asia-Pacific region performed well in compliance compared to other regions, with the hospitality sector slightly lagging behind.

In summary, PCI compliance is a critical aspect of secure credit card processing, offering substantial benefits for businesses while helping protect cardholder data. The drawbacks of non-compliance, including hefty fines and reputational damage, underscore the necessity of adhering to these standards. To maintain the trust of customers and ensure the security of financial transactions, businesses must prioritize PCI compliance.
