Session replay captures the full interaction between a user and your application. It records input fields, clicks, and responses—everything an attacker needs to reproduce the sequence. For merchants, processors, and developers working with cardholder data, this is a direct compliance and security risk. PCI DSS requires strict protections for sensitive authentication data, including session IDs and any element that could lead to account takeover. Session replay recordings that contain PAN, CVV, expiration dates, or customer credentials are a violation.
Why Session Replay Violates PCI DSS
Under PCI DSS Requirement 3, cardholder data must be stored and transmitted securely. Requirement 8 demands robust authentication controls. If a replay file contains unmasked data or authentication tokens, it is equivalent to storing raw card data without encryption. Additionally, Requirement 10 mandates logging access, but not recording sensitive fields. A session replay tool that grabs full DOM states without redaction breaches both security and compliance.
Secure Alternatives
You do not need to abandon insight into user activity. PCI DSS–compliant solutions scrub sensitive fields before storage or transmission. They use masking, tokenization, and strict retention limits. Metadata can be preserved for debugging without capturing actual cardholder input. Strong role-based access ensures that even authorized staff cannot retrieve sensitive segments unless required for operations.
