What is Email Redaction?

Email redaction is the process of permanently removing or obscuring sensitive information from existing email archives that have been exported from email platforms. This is essential when processing .mbox and .pst files for legal discovery, FOI requests, or compliance purposes where sensitive data needs to be protected before sharing or archiving.

Manual vs Automated Email Redaction

  • Time-consuming and error-prone

    Each email file (.mbox/.pst) must be reviewed individually

  • Limited to basic tools
