    Overview

    Play video

    Email remains the #1 cause of breaches and #1 source of cybercrime losses to enterprises (Source: FBI Internet Crime Report). As attackers leverage generative AI and sophisticated social engineering, traditional security approaches that rely on threat intelligence and static rules are no longer sufficient. Organizations need a modern solution that deeply understands human behavior to protect against these evolving threats.

    Abnormal Security delivers unprecedented protection through its AI-native platform for human behavior security. By leveraging a unique API-based architecture, Abnormal ingests 10x more behavioral signals than legacy solutions, enabling deep understanding of every employee and vendors behavior patterns. This foundation powers precise detection of anomalies and suspicious activities, stopping advanced attacks like business email compromise, supply chain fraud, account takeovers, lateral phishing, and AI-generated impersonation attempts before they can cause damage. For example, Abnormal detected and stopped a $13.5M payment fraud attempt where an attacker compromised an email account, created a look-alike domain, and sent a fraudulent invoice. Abnormals AI flagged anomalies such as the newly registered domain, suspicious email headers, and unusual language patterns, preventing the attack before any harm occurred.

    Beyond superior detection, Abnormal transforms security operations through AI automation. The platforms AI Security Mailbox eliminates manual triage and investigation of reported emails, while automated remediation capabilities instantly remove threats across all mailboxes. This automation, combined with features like AI-generated security awareness training and intelligent graymail management, reduces SOC workload by 95% while improving employee productivity.

    Deployed in 60 seconds via API, Abnormal integrates seamlessly with Microsoft 365 and Google Workspace without the need for professional services or ongoing admin overhead.

    Key Benefits -Integrates in 60 seconds, deploys without professional services, and operates autonomously with no admin overhead. -Leverages behavioral AI to detect and stop novel email attacks while fully automating SOC operations, including phishing mailbox management, security training, and attack remediation. -Expands protection beyond email by using human behavioral AI to detect and remediate account takeovers (ATO/UATO), securing cloud platforms and preventing unauthorized access.

    Abnormal is recognized for its customer-first approach and commitment to innovation. Named a "Leader" in the Gartner Magic Quadrant for Email Security Platforms with the "Most Completeness of Vision," Abnormal also boasts a 99% customer "Would Recommend" rating, reflecting its industry leadership and dedication to excellence.

    Enhanced Email Security, But Needs AI Coach Improvement

    Reviewed on Mar 09, 2026
    Review provided by G2
    What do you like best about the product?
    I like that since adding Abnormal AI to our setup, we've seen a drastic reduction in phishing emails, credential theft, and malicious team messages. Before, we were inundated with phishing emails bypassing our old email security, but Abnormal AI significantly reduces those threats. I appreciate that it provides an additional layer of email security and automatically manages phishing and promotional emails, boosting our team's productivity. The initial setup was also very easy—an Abnormal AI engineer guided us through it, and we managed to complete 90% of the configuration in just a one-hour meeting.
    What do you dislike about the product?
    The AI Phishing Coach module is still premature and needs improvement for enterprise-level use. The audio of the AI lady, Jess, in the module doesn't synchronize. Her head was cut at some parts of the video, clearly showing it's an AI-generated video and voice. It needs a bit more realistic appearance and voice.
    What problems is the product solving and how is that benefiting you?
    Abnormal AI provides additional email security, automatically removes phishing emails, and increases productivity by sorting promotional emails. It has drastically reduced phishing emails, credential theft, and malicious messages, which previously bypassed our email security.
