Beyond Encryption Mailock for Outlook vs Echoworx Branding as a Service: 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. Mid-market and enterprise teams deploying Echoworx email encryption need this if your security posture depends on user adoption, and white-label branding is your lever to get there. Echoworx Branding as a Service covers the visual layer completely,vanity domains, localized templates across 28 languages, and mobile-optimized portals,removing the friction that kills encryption adoption rates. Skip this if your organization has already standardized on a different encryption vendor or if your users don't interact with secure link portals frequently enough to justify the branding investment.
