A Fundamentally Different Approach to Email Security

Abnormal is the most precise human behaviour security engine for blocking all email attacks, including phishing, malware, ransomware, social engineering, executive impersonation, supply chain compromise, internal account compromise, spam, and graymail.

Secure email gateways and built-in Microsoft and Google security struggle to block email attacks that pass reputation checks, have no URLs or attachments, and appear to come from trusted sources.

Only Abnormal uses behavioural AI to profile known good behaviour and analyses over 45,000 signals to detect anomalies that deviate from these baselines, delivering maximum protection for global enterprises.
