About Abnormal Security AI
Abnormal Security is an AI-powered email security platform that uses behavioral AI to detect and block sophisticated email attacks—including business email compromise (BEC), spear phishing, vendor email compromise, and account takeover—that bypass traditional secure email gateways. By building a behavioral baseline of every user's email communication patterns, Abnormal detects anomalies that indicate compromised accounts or impersonation attacks even when messages contain no malicious links or attachments. The platform integrates with Microsoft 365 and Google Workspace via API, requiring no MX record changes, and autonomously remediates malicious emails from user inboxes post-delivery. Organizations including Xerox, Groupon, and XEROX have reduced email-based security incidents by over 90% with Abnormal.
