Compare features, ratings, integrations, and community reviews side by side to find the best email security platforms fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams managing Microsoft 365 across multiple tenants will get the most from Mesh 365 for its cross-tenancy visibility and centralized threat remediation, capabilities most native M365 security tools lack. The API-based architecture delivers impersonation detection and business email compromise protection without the detection gaps that plague perimeter-only defenses, and the monitor-only evaluation mode lets you validate rules before enforcement. Skip this if you need deep integration with non-Microsoft email systems or expect your vendor to handle incident response; Mesh 365 prioritizes detection and analysis over recovery automation.
SMB and mid-market teams defending Microsoft 365 or Google Workspace without dedicated security staff should start with ESET Cloud Office Security; its cloud-based management console and automatic user protection mean you configure once and stop worrying about coverage gaps as headcount shifts. The tool scores notably on DE.CM Continuous Monitoring and DE.AE Adverse Event Analysis, meaning you get real anomaly detection rather than just signature-based blocking. Skip this if your organization needs deep integration with on-premises Exchange or requires sandbox detonation as a primary control rather than a secondary layer for zero-days.
