That’s the problem. Session replay tools show you exactly what a user does — even the things you should never see. Password fields. Social Security numbers. Private messages. Without controls, you’re not just debugging software. You’re capturing sensitive data you have no right to keep.
Dynamic data masking in session replay changes that. It hides sensitive information in real time, before it ever reaches disk, a server, or your eyes. The value is clear: you get the insight you need from replays without the legal risk, compliance headaches, or trust issues.
It works by identifying and masking protected data — like payment details, names, addresses, ID numbers — at capture. Instead of a card number, you’ll see masked symbols. Instead of an unmasked password, you’ll see nothing. All while keeping the rest of the session replay intact, so you can still track clicks, movements, and flows.
When implemented correctly, dynamic masking is done at the edge. That means no unmasked data enters your logs or storage. You reduce the risk surface dramatically. Compliance with GDPR, PCI DSS, HIPAA, and other privacy regulations becomes easier. You stay audit-ready without slowing down your debugging process.
