Beyond Encryption Mailock for Outlook vs Seclore Email Encryption: Side-by-Side Comparison (2026)

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.

Seclore Email Encryption

Mid-market and enterprise teams handling regulated data will find real value in Seclore Email Encryption's ability to revoke access to sent emails after delivery, which standard TLS encryption simply cannot do. The tool covers both PR.DS data security and DE.CM continuous monitoring under NIST CSF 2.0, meaning you get encryption plus audit trails that actually matter for compliance audits. Skip this if your primary concern is stopping inbound phishing; Seclore is built for controlling what happens to sensitive data after it leaves your organization, not filtering what comes in.
