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 security teams managing Microsoft 365 will get the most from TrustLayer Mail because it blocks inbound threats without forcing MX record changes, cutting through the deployment friction that kills most email security projects. Click-time URL scanning catches phishing that gateway filters miss, and the compliant archiving with eDiscovery eliminates the need for a separate archive tool. Skip this if you need on-premises Exchange support or are heavily invested in third-party email systems; TrustLayer's strength is specifically in 365 environments where transport rules and connectors handle the heavy lifting.
