Abnormal Inbound Email Security
AI-based inbound email security that detects BEC, phishing, vendor fraud, and account takeover using behavioral analysis.

Abnormal Inbound Email Security builds behavioral baselines for employees and vendors, then detects email attacks that may lack malicious payloads, known signatures, or authentication failures. It supports investigation, remediation, quarantine review, and custom detection controls.
Security operations teams use it with Microsoft 365 and Google Workspace. Deployment uses an API without MX changes. Abnormal does not publish public pricing; customers must request a demo, and some related products or capabilities may be separate add-ons.
