Vendor Profile

Abnormal Security

Abnormal Security is an AI-native email security platform that uses behavioral AI to detect and block socially-engineered email attacks that bypass traditional email security gateways. Rather than relying on signatures, threat feeds, or URL scanning, Abnormal builds behavioral profiles of every identity in the organization and detects anomalies in communication patterns, writing style, and email metadata. This approach is particularly effective against business email compromise, vendor fraud, and account takeover attacks that contain no malicious payloads for traditional tools to catch.
