PCI DSS 4.0 strengthens payment data security by requiring continuous monitoring, stronger cryptography, tighter access controls and clearer governance. The paper explains how Thales supports compliance with encryption, key management, tokenization, data discovery, HSMs, high speed network encryption and access management. These tools help protect cardholder data at rest and in motion, restrict access, enforce secure configurations, monitor activity and streamline audits. Thales solutions provide centralized control, automate key lifecycles and reduce risk across on-premises and cloud environments, helping organizations meet evolving PCI obligations.
