Beyond Encryption Mailock for Outlook vs Virtru Google Workspace Encryption and Data Privacy: Side-by-Side Comparison (2026)

Short answer

SMB and mid-market teams that need to stop encrypted emails from being forwarded or screenshotted after delivery should use Beyond Encryption Mailock for Outlook, since message revocation works even after recipients have opened attachments. The tool covers NIST PR.DS and PR.AA through AES-256 encryption and multi-factor recipient authentication, eliminating the "trust the recipient" problem that plagues standard TLS. Skip this if your org requires integration with Gmail or non-Microsoft clients; Mailock is Outlook-only and leaves users on other platforms without encryption protections. Teams invested in Google Workspace who need encryption that doesn't break user workflows will see immediate value in Virtru Google Workspace Encryption and Data Privacy, since it encrypts Gmail, Drive, Meet, and Docs natively without forcing users into separate portals. FIPS validation and private key hosting mean you can satisfy compliance auditors without pretending Google holds your encryption keys. Skip this if your organization runs email outside Google Workspace or needs DLP that catches exfiltration before it leaves your network; Virtru prioritizes encryption and access control over anomaly detection.
