Compare features, ratings, integrations, and community reviews side by side to find the best email security platforms fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams running on-premises Exchange Server need Messageware EPG for its protocol-level attack detection, which stops both high-volume brute force and low-volume targeted password guessing that Active Directory lockout thresholds miss entirely. The independent lockout system reduces help desk friction while real-time monitoring across nine Exchange protocols catches threats at the gateway before they reach mailboxes. Skip this if you've already migrated to Microsoft 365; EPG is built for hybrid or fully on-premises deployments and won't add value in cloud-only environments.
Fortinet FortiMail Email Security
Mid-market and enterprise teams defending Microsoft 365 or Google Workspace environments should prioritize FortiMail for its pattern-based anomaly detection, which catches business email compromise and account takeover attempts that signature-only solutions miss. The platform's dual protection via gateway and API, combined with real-time FortiGuard threat intelligence, covers both inbound phishing and outbound data exfiltration, scoring strong on NIST DE.CM continuous monitoring. Skip this if your organization needs deep Slack or third-party collaboration app coverage; FortiMail's strength is email-specific, not broader communication channels.
