PCI DSS

The Payment Card Industry Data Security Standard — mandatory security requirements for any organization that stores, processes, or transmits cardholder data.

Definition

What is PCI DSS?

PCI DSS (Payment Card Industry Data Security Standard) is a set of technical and operational requirements established by the Payment Card Industry Security Standards Council (PCI SSC) to protect cardholder data. Version 4.0 (released 2022, mandatory compliance March 2025) covers 12 requirement areas: network security, cardholder data protection, vulnerability management, access control, monitoring, and information security policy. Any organization that stores, processes, or transmits credit or debit card data — merchants, payment processors, service providers, banks — must comply.

Why It Matters

PCI DSS non-compliance exposes organizations to fines from card brands (Visa, Mastercard) of $5,000–$100,000 per month, increased transaction fees, loss of card processing privileges, and liability for fraud losses. Card data remains one of the most stolen and monetized assets in the criminal economy. For e-commerce, financial services, and retail organizations, PCI DSS compliance is the baseline expectation of every payment processor and acquiring bank.

How It Works

PCI DSS compliance is validated annually through a Self-Assessment Questionnaire (SAQ) for smaller merchants or a Report on Compliance (ROC) conducted by a Qualified Security Assessor (QSA) for larger organizations. The assessment covers network segmentation (reducing PCI scope), cardholder data environment (CDE) controls, penetration testing, vulnerability scanning, logging, and access control. Version 4.0 introduces significant new requirements around authentication, phishing resistance, and application security.
