Masking Sensitive Data in Session Recordings for Compliance

The cursor blinks. Sensitive data appears on the screen. A single leak could break trust, violate law, and cost millions.

Masking sensitive data during session recording is no longer optional. Compliance frameworks like GDPR, HIPAA, PCI-DSS, and SOC 2 demand it. Real-time masking prevents exposure of personal identifiers, payment details, health records, or credentials before they ever reach storage.

Unmasked session recordings are a liability. Every keystroke, every form fill, every API key entered can become an incident. Masking replaces this raw input with placeholder data—rendering recordings safe while preserving the context needed for debugging, user research, and audit trails.

Effective data masking for compliance starts in the recording pipeline. Capture events with minimal latency. Apply field-based masking rules for input elements like <input type="password">, email fields, and credit card entries. Ensure structured JSON payloads and unstructured DOM nodes are sanitized before writing to disk. Use deterministic masking to keep user flow intact without revealing the original values.

A compliant session recording system should:

• Apply masking client-side to keep sensitive values from being sent.
• Support dynamic masking rules that match selectors, patterns, and data types.
• Maintain usability of recordings with clear placeholders.
• Log masking actions for audit evidence.
• Pass third-party privacy and compliance audits before deployment.

Masking sensitive data protects users and meets legal requirements. It also lowers the burden on engineering and compliance teams. With proper implementation, you gain observability into sessions without sacrificing security or privacy.
