Why Choose Abnormal Security Over MimeCast Email Security

Best for AI-Driven Threat Detection

Abnormal takes a behavioral approach to detecting email threats, flagging anomalies that signature-based tools often miss. It works on top of existing email platforms rather than replacing them, which makes it a compelling add-on or replacement for teams frustrated with Mimecast's detection gaps on social engineering attacks.
