What feature allows protecting confidential user data during Session Replay?

Data masking rules are essential in protecting confidential user data during Session Replay by allowing sensitive information to be obscured or anonymized. This functionality is critical in environments where customer privacy must be ensured, especially in compliance with data protection regulations such as GDPR or CCPA.

With data masking rules, organizations can specify which data fields or types of information should not be visible during replay, helping to prevent the exposure of personally identifiable information (PII) or other sensitive data. This ensures that while the Session Replay provides valuable insights into user interactions and behavior, it does so without compromising user confidentiality.

The other options, while important in their respective areas, do not specifically target the protection of sensitive data during the replay process as effectively as data masking rules do. Content blockers may restrict certain elements from being loaded, but they do not inherently protect confidential information. Permission controls manage access to data but do not mask it during replay, and session timeouts help control session duration without addressing confidentiality during the actual replay process.
