Company Description

Abnormal AI provides an AI-native security platform focused on protecting against advanced email and cloud application attacks. The company’s core products use behavioral analysis to detect and block threats like business email compromise and to identify account takeovers. Founded in 2018 by Evan Reiser and Sanjay Jeyakumar, the company was originally known as Abnormal Security. It has since grown to over 1,000 employees with a headquarters in Las Vegas and international offices in London and Bengaluru.

The company continues to expand its operations, backed by a recent Series D funding round in September 2024 that raised $250 million. Abnormal AI actively publishes threat intelligence, such as a recent brief on a new phishing toolkit called Impact Solutions, and engages with the security community through events like its "Good AI vs. Bad AI Roadshow." A notable customer deployment with Los Angeles County reportedly reduced the county's phishing tickets from 75,000 to 2,000 and saved nearly $4 million in staff time. Future plans include expanding its roadshow to more cities and continuing research and development in AI-driven security solutions.
