About
Abnormal Security delivers enterprise-grade cloud email protection powered by its proprietary Behavioral AI engine. Unlike traditional rule-based or signature-driven security tools, Abnormal builds a deep understanding of human communication patterns and organizational behavior to identify anomalies that indicate malicious intent — even zero-day attacks that have never been seen before. The platform's core product, the Abnormal Behavior Platform, provides multi-layered defense across cloud email environments, protecting against credential phishing, spear-phishing, business email compromise (BEC), vendor fraud, and social engineering. Beyond email, the platform extends protection to SaaS applications with account takeover detection and misconfiguration monitoring. Abnormal also offers AI Security Agents — autonomous agents purpose-built to streamline repetitive Security Operations Center (SOC) workflows, allowing security teams to operate at machine speed. The platform detects and neutralizes threats in milliseconds with no manual intervention required. Recognized as a Leader in the inaugural 2024 Gartner Magic Quadrant for Email Security Platforms, Abnormal is the choice for large enterprises seeking to reduce risk from AI-generated and hyper-personalized email attacks. It is purpose-built for organizations using Microsoft 365 or Google Workspace and integrates seamlessly via API with no MX record changes needed.

Frequently Asked Questions
What is Abnormal Security?
Abnormal Security is a cloud email security platform that uses behavioral AI to autonomously detect and block advanced email threats including phishing, business email compromise (BEC), and account takeovers.
How does Abnormal's behavioral AI work?
Abnormal's AI analyzes thousands of signals about users, relationships, and communication patterns to build a behavioral baseline. Any deviation from that baseline — such as an unusual request from a 'known' contact — is flagged and blocked automatically.
What email platforms does Abnormal Security support?
Abnormal Security integrates natively with Microsoft 365 and Google Workspace via API, requiring no changes to MX records or mail routing.
Is there a free trial available?
Abnormal Security is an enterprise product and does not advertise a self-service free trial. Prospective customers can request a demo through the Abnormal website to evaluate the platform.
How is Abnormal different from traditional email security tools like SEGs?
Traditional Secure Email Gateways (SEGs) rely on signatures, rules, and reputation lists. Abnormal uses behavioral anomaly detection to catch zero-day and AI-generated attacks that have no known signatures, stopping threats that SEGs routinely miss.
