Summary: The PCI DSS 4.0.1 introduces substantial updates to enhance cybersecurity in the payment industry while remaining user-centric in its design. The standard emphasizes “what” needs to be achieved rather than “how,” fostering a collaborative industry response instead of bureaucratically driven regulations. Recent critiques highlight its strengths and weaknesses, particularly regarding multifactor authentication and compliance with broader regulations like GDPR and the AI Act.
