PCI DSS (Payment Card Industry Data Security Standard) 4.0 represents a significant update poised to reshape compliance and audit processes; it is thought to be one of the most impactful changes since the development of PCI DSS.

These updates underscore the critical need for organizations to adopt proactive measures to ensure compliance and fortify their cybersecurity posture.
