Messageware EPG vs Vircom Email Security: Side-by-Side Comparison (2026)

Messageware EPG

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.

Vircom Email Security

MSPs and mid-market IT teams managing multiple customer tenants will get the most from Vircom Email Security because its multi-tenant dashboard and PSA billing integration eliminate the operational friction of juggling separate portals and invoice reconciliation. The automated client onboarding and account takeover detection cover both the administrative overhead (PR.AA) and detection gaps (DE.CM) that plague distributed deployments. Skip this if your organization needs a single vendor to handle email, endpoint, and network security under one contract; Vircom stays disciplined in email and leaves the rest alone.
