689Cloud SecureMail vs Egress Prevent: Side-by-Side Comparison (2026)

Egress Prevent

Mid-market and enterprise teams drowning in misdirected email incidents will see immediate value in Egress Prevent's relationship mapping engine, which flags messages sent to wrong recipients before they land in inboxes. The tool's real-time point-of-send detection and Bayesian inference for continuous risk assessment directly address PR.DS (data security) and DE.CM (continuous monitoring) under NIST CSF 2.0, meaning you're stopping exfiltration at the moment of highest visibility. Skip this if your organization needs broader insider threat capabilities beyond email; Egress Prevent owns the send-time problem but doesn't replace behavioral analytics for lateral movement or cloud data access abuse.
