Beyond Encryption Mailock Enterprise vs Virtru Gmail Encryption: Side-by-Side Comparison (2026)

Short answer

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. Mid-market and enterprise security teams that need to revoke or expire sensitive emails after sending will find real value in Virtru Gmail Encryption; message recall is the rare email encryption feature that actually works at scale. The tool validates FIPS encryption standards and integrates directly into Gmail without requiring users to leave their inbox, which keeps adoption friction low. Skip this if your organization needs DLP automation to drive policy enforcement rather than just flag violations; Virtru's rule-based encryption is a control, not a prevention layer.
