The PCI DSS was developed to enhance payment card account data security globally by promoting consistent data security measures. It provides a baseline of technical and operational requirements intended for entities that store, process, or transmit cardholder data, including merchants, processors, and service providers. The latest version, PCI DSS v4.x, introduces additional flexibility and updated requirements to address emerging threats and technologies. Compliance is typically mandated by card brands or acquirers. Resources include documentation, training, qualified assessors, and vulnerability scanning services to help organizations adhere to the standard.
