PCI DSS – what is it?

Payment Card Industry Data Security Standard (PCI DSS) is a payment card data security standard that establishes mandatory requirements for protecting cardholder information during storage, processing, and transmission. The international PCI DSS standard was developed by a consortium of payment systems and defines a set of technical and organizational controls, including network segmentation, data encryption, access control, security event monitoring, and regular vulnerability testing. The standard covers all components of the infrastructure that interact with cardholder data, including networks, servers, applications, and management processes.

In practical application, PCI DSS is mandatory for organizations that accept, process, or store payment card data, including banks, payment providers, and e-commerce platforms. Implementation of the standard involves регулярні audits, vulnerability scanning, log monitoring, and maintaining an up-to-date level of infrastructure security. Compliance with PCI DSS reduces the risk of financial data compromise, ensures adherence to payment network requirements, and increases user trust in digital payment services.
