What is PCI security?

PCI security refers to the set of standards and practices established to protect credit card data and ensure secure payment transactions. The Payment Card Industry Data Security Standard (PCI DSS) is a widely recognized framework that outlines technical and operational requirements for organizations that handle cardholder information. Compliance with PCI security helps prevent data breaches, fraud, and unauthorized access to sensitive payment data. Businesses that process, store, or transmit credit card information must follow these guidelines to maintain trust and avoid penalties.
