PCI Pal Glossary

PCI DSS Compliance

PCI DSS compliance (Payment Card Industry Data Security Standard compliance) refers to meeting the security requirements established by major credit card companies to protect cardholder data during payment transactions. Organizations that store, process, or  transmit credit card information must implement specific security controls including network firewalls, encryption, access controls, and regular security testing.

Compliance levels vary based on transaction volume, with requirements ranging from annual self-assessment questionnaires for smaller merchants to comprehensive on-site audits for large processors. Maintaining PCI DSS compliance helps prevent data breaches, protects customers, and avoids costly penalties from card brands.
