The screen freezes. A cursor blinks. Somewhere, a compliance officer asks for proof.
Session replay has become a crucial tool for legal compliance in regulated industries. It records the exact sequence of user actions in an application — clicks, inputs, and navigation — capturing both visual output and underlying data state. For legal teams, this is evidence. For engineers, it is a technical challenge: building accurate, privacy-safe replays that meet regulatory standards without slowing the product.
Legal compliance demands precision. GDPR, CCPA, HIPAA, PCI-DSS — each has rules on how user data can be collected, stored, and accessed. A compliant session replay must mask sensitive fields like passwords, credit card numbers, or protected health information before they are logged. Masking is not enough; proper encryption at rest and in transit must follow. Access controls should limit replay views only to authorized personnel, with audit logs tracking each time a session is opened.
Retention policies are a compliance fault line. Keep data too long and you risk fines; delete too soon and you lose the forensic trail. Work from the regulations backward: store only what each standard allows, for as long as it allows. Implement automated deletion jobs so nothing lingers past the retention window.
