Is your business ready for PCI DSS 4.0? Discover new requirements, timelines, and a practical guide to staying compliant and protecting payment data.
The Payment Card Industry Data Security Standard has undergone major modernization in recent years. PCI DSS 4.0 introduced a more flexible, risk-driven framework designed for cloud-native systems, distributed architectures, and modern ecommerce environments. But as organizations began applying the new requirements, several areas of PCI DSS 4.0 were interpreted inconsistently.
To address these issues, the PCI Security Standards Council released PCI DSS 4.0.1, a maintenance update that clarifies the standard and removes ambiguity. While 'PCI DSS 4.0' remains the widely searched term, PCI DSS 4.0.1 is now the active version organizations must use for all assessments in 2025.
