We Stop Attacks
Others Can’t

The Behavioral Security Platform for the AI era.

Over 25% of the Fortune 500 Trust Abnormal AI to Make Automated, Critical Security Decisions

The Problem

AI gives attackers
speed, scale, and sophistication.

Machine Speed

Attacks move in milliseconds, faster than any human can respond.

See how fast AI breaches land and expand

Unprecedented Scale

AI enables more criminals to send more attacks at more surface areas.

See how AI-powered actors overwhelm human defenses

Novel Techniques

AI-generated attacks are often too subtle for humans to see and too new for traditional threat intel to detect.

See the sophistication of GenAI social engineering

The Solution

To fight bad AI you need Behavioral AI.

AI attackers have to look normal every time.
They can’t.

Behavioral context unlocks automated AI defense.
