PreVeil Security is a commercial email encryption tool by PreVeil. Beyond Encryption Mailock for Outlook is a commercial email encryption tool by Beyond Encryption. Compare features, ratings, integrations, and community reviews side by side to find the best email encryption fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams handling classified or controlled data will get the most from PreVeil Security because its zero-trust architecture eliminates the server as a decryption point, which is the actual attack surface most email encryption tools ignore. DFARS and ITAR compliance is built in, not bolted on, and the cryptographic key-based authentication replaces the password attack vector entirely. Skip this if your organization needs broad endpoint protection or threat detection; PreVeil is encryption and access control, period, and it assumes you're handling that threat layer elsewhere.
Beyond Encryption Mailock for Outlook
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.
