Abnormal Security revolutionizes email protection with behavioral AI that understands normal communication patterns and detects sophisticated threats through anomaly detection. Unlike traditional signature-based solutions, Abnormal establishes baselines of organizational behavior and identifies deviations that signal malicious intent, making it exceptionally effective against never-before-seen attacks. The platform integrates seamlessly with Microsoft 365 and Google Workspace via API, augmenting existing security tools without requiring MX record changes or email routing disruption. Ideal for enterprises seeking advanced protection against business email compromise (BEC), executive impersonation, and account takeover attacks that regularly evade conventional email security gateways.
