Beyond Encryption Mailock® Secure Email vs PreVeil Security: Side-by-Side Comparison (2026)

Beyond Encryption Mailock® Secure Email

Teams handling regulated data who need proof that sensitive emails were opened, not just sent, should consider Beyond Encryption Mailock® Secure Email; message tracking and revocation give you the audit trail that generic TLS encryption cannot. AES-256 encryption with multi-factor recipient verification covers the NIST PR.DS and PR.AA controls auditors actually ask for. Skip this if your priority is preventing internal data exfiltration rather than securing external communication; Mailock assumes the recipient's inbox is the trust boundary, not an extension of your network.

PreVeil Security

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.
