Beyond Encryption Mailock for M365 vs Sekur Private Data: Side-by-Side Comparison (2026)

Beyond Encryption Mailock for M365

SMB and mid-market teams standardized on Microsoft 365 should pick Beyond Encryption Mailock for M365 if message revocation is non-negotiable; the ability to recall emails even after a recipient opens them covers the mistake you'll inevitably make sending sensitive data to the wrong person. AES-256 encryption with SMS and Q&A recipient verification handles NIST PR.AA without requiring users to manage separate identity infrastructure. Skip this if your organization needs DLP that catches data before it leaves the network or if you're already enforcing encryption at the gateway level; Mailock layers on top of M365 rather than replacing email security controls.

Sekur Private Data

Teams that need encrypted comms fully outside U.S. jurisdiction will find Sekur Private Data's Swiss hosting and FADP compliance genuinely useful, particularly if regulatory or client contracts explicitly prohibit American data centers. The ISO-certified infrastructure and self-destruct messaging cover the core use cases for legal firms and healthcare practices handling sensitive correspondence. Skip this if your primary need is email security against inbound threats like phishing or malware; Sekur is a confidentiality tool, not a detection layer, and lacks the threat intelligence integration that catches compromised sender accounts or credential harvesting campaigns.
