What Abnormal Email Security is

Abnormal Email Security is a cloud service that uses behavioral AI to detect email threats such as business email compromise, vendor fraud, account takeover and AI-generated attacks. Its Attune foundation model builds behavioral baselines for individual identities and looks for deviations. The product page describes API deployment in 60 seconds. Search & Respond supports threat hunting, triage and remediation across Microsoft 365 and Google, with more than 30 search filters. Custom AI Models lets users build detection models from email examples and natural-language descriptions, then test them against historical messages. Detection 360 investigates submitted missed attacks and false positives, explains outcomes and updates detection models. Other tools automate analysis of user-reported phishing and filter graymail, including newsletters and promotions. The product page also describes behavioral AI protection for Slack, Microsoft Teams and Zoom. Listed integrations include security, identity and service-management tools. Abnormal says it maintains SOC 2 certification and holds several ISO certifications. Pricing is per-user mailbox, varies by platform features and is available through a preferred partner or a private Azure Marketplace offer.
