Beyond Encryption Mailock Enterprise vs Egress Protect: Side-by-Side Comparison (2026)

Beyond Encryption Mailock Enterprise

Mid-market and enterprise security teams handling regulated data across Microsoft 365 and Google Workspace need Mailock Enterprise because its trigger-word detection and rule-based automation remove the human decision from when to encrypt,the actual failure point in most email security programs. The platform covers NIST PR.DS (data confidentiality via AES-256) and PR.AA (recipient authentication across SMS, Q&A, and Unipass ID) without requiring users to remember to act. Skip this if your organization has under 500 seats or needs DLP beyond keyword matching; Mailock solves encryption governance, not content discovery.

Egress Protect

Mid-market and enterprise teams protecting sensitive data in Microsoft 365 should choose Egress Protect for its post-send message control, which lets you revoke access and restrict forwarding even after recipients open encrypted email. The tool covers three NIST CSF 2.0 functions (PR.DS, PR.AA, DE.CM), with particular strength in access enforcement through granular controls and continuous audit trails that satisfy compliance auditors. Skip this if you need unified DLP across cloud storage, web, and endpoints; Egress Protect is email-centric and won't replace a platform-wide data loss prevention strategy.
