Abnormal Security

Born from the minds of co-founders Evan Reiser and Sanjay Jeyakumar in 2018, Abnormal Security embarked on a mission to redefine email security. With backgrounds in advertising technology and machine learning at giants like Twitter, the founders recognized a critical vulnerability in the business world: the rising tide of sophisticated, socially-engineered email attacks that traditional security gateways were failing to catch. They envisioned a new approach, one that didn't just look for known threats but understood the nuances of human behavior. This led to the creation of a cloud-native platform built on a foundation of AI and behavioral data science. The core idea was to create a baseline of normal communication patterns within an organization—understanding who talks to whom, about what, and when—to instantly spot anomalies that signal a potential attack, from business email compromise to vendor fraud.

This innovative, AI-driven strategy quickly gained traction. What started as a focused solution to a complex problem has since blossomed into a comprehensive security powerhouse. The company's journey has been marked by rapid growth, securing significant funding rounds, including a Series C that propelled its valuation to $4 billion. This financial backing has fueled continuous innovation, expanding the platform's capabilities beyond inbound email to include protection against account takeovers and automated security operations. Today, Abnormal Security protects a significant portion of the Fortune 1000, with major companies like Xerox and Foot Locker trusting its platform. The team, a blend of AI experts from Google and Amazon and cybersecurity veterans from Proofpoint and FireEye, remains dedicated to its founding principle: protecting the human element of the enterprise from the next generation of cyber threats, ensuring that as attackers evolve, their defenses evolve faster.
