Abnormal AI runs an email security platform that uses behavioral AI to detect phishing, business email compromise, and account takeovers by modeling normal user behavior. It serves Microsoft 365 and Google Workspace enterprises, including 25% of the Fortune 500. Unlike signature-based gateways, Abnormal catches BEC that bypasses M365.
