Abnormal Security

Abnormal Security is a cloud-native email security platform that uses behavioral AI to detect and prevent sophisticated email attacks such as business email compromise (BEC), phishing, and social engineering. Unlike traditional email security that relies on rules and signatures, Abnormal builds a baseline of known-good behavior for every user and organization to identify anomalies. 

The platform integrates directly with Microsoft 365 and Google Workspace via API, requiring no changes to mail routing or MX records. It provides protection against account takeovers, supply chain fraud, and invoice manipulation attacks, making it particularly effective against threats that bypass conventional secure email gateways.
