What is PCI DSS 4.0? When does it take effect?

What is PCI DSS 4.0? 

PCI DSS 4.0 is the latest version of the Payment Card Industry Data Security Standard, published to address evolving security challenges and technological advancements. It introduces updates and enhancements to the framework, aligning it with current industry trends and emerging threats. PCI DSS 4.0 provides organizations with the tools and guidelines needed to maintain a secure payment environment in the face of changing cybersecurity landscapes. 

When does PCI DSS v4.0 take effect? 

The transition to PCI DSS v4.0 will span a two-year period, ensuring a smooth shift from the current version, PCI DSS v3.2.1. Until March 31, 2024, PCI DSS v3.2.1 will remain active and in use. Following this date, PCI DSS v4.0 will become the sole active version. As is customary with significant version updates, new requirements are anticipated, which are scheduled to become enforceable after March 31, 2025. Until that time, these requirements are considered best practices, allowing organizations a substantial window to prepare and adapt. This transition timeline offers companies ample opportunity to align their practices with the evolving standard.
