INKY Graymail Protection vs Mesh 365: 2026 Comparison

Mesh 365

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.
