Abnormal AI

Abnormal AI protects enterprises from email attacks using behavioral AI that understands identity and behavior to stop phishing and fraud.

Overview

Abnormal AI secures cloud email — Microsoft 365 and Google Workspace — by learning the normal behavior of every employee, vendor, and executive. Its behavioral AI detects phishing, account takeover, vendor fraud, and social-engineering attacks that slip past secure email gateways. The platform also automates abuse-mailbox triage and provides posture management for email security configuration. Enterprises adopt Abnormal to combat sophisticated BEC and phishing campaigns, reporting significant reductions in delivered attacks.

Abnormal approaches email security from identity: by learning how every person and organization communicates, it detects the anomalies that signal compromise — an executive’s writing pattern shifting, a vendor’s banking details changing, a thread hijacked mid-conversation. Behavioral detection catches the sophisticated BEC and social-engineering attacks that gateways pass through, since nothing malicious is attached or linked. API-based deployment covers the full mailbox estate within hours, and posture management closes configuration gaps that attackers exploit. ROI reporting quantifies prevented fraud attempts and saved SOC time, which security leaders need for renewal conversations. For organizations where email fraud is measured in real money — finance, procurement, real estate — Abnormal’s identity-based detection routinely stops losses that conventional filters never see.
