Abnormal Security Cloud-based email security platform
Mid-market and enterprise security teams drowning in phishing and business email compromise alerts should evaluate Abnormal Security Cloud-based email security platform for its behavioral AI detection, which catches account takeovers and zero-day attacks that signature-based filters routinely miss. The platform scores strongly on NIST DE.CM and DE.AE, meaning it's built for continuous anomaly hunting and incident characterization rather than just blocking known threats. Skip this if your org needs thick integration with legacy on-premises email systems or requires extensive customization; Abnormal's API-first cloud design assumes you've already migrated away from that complexity.
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.
