About Abnormal AI

Abnormal AI sells a behavioral security platform that protects email, identity, and AI.

Abnormal AI states its mission is to stop crime with AI.[15]

Abnormal AI says its platform connects AI tools, people, agents, and cloud activity through behavioral context to govern adoption, enforce policies, detect threats, and support investigations. The platform has native API integrations across Microsoft 365, Google Workspace, Okta, CrowdStrike, and the customer's SIEM and SOAR. Abnormal AI says each supported connection helps Abnormal understand activity, investigate threats, and apply the controls the customer's team authorizes.
