Abnormal Security

Abnormal Security was founded in 2018 by Evan Reiser - CEO, Sanjay Jeyakumar - CTO, Jeshua Bratman - Head of Machine Learning, and Founding Engineers - Dmitry Chechik and Abhijit Bagri. The headquarters is located in San Francisco, California. The Abnormal Security platform shields companies from targeted email attacks. Abnormal Behavior Technology (ABX) mirrors the identity of company employees and external senders. It profiles relationships, assesses each organization and examines email content to halt attacks that precede financial damage, account takeover and organizational mistrust. They are backed by Greylock Partners, a venture capital firm based in Silicon Valley.

Their cloud-native architecture operates via one-click, API-based Office 365 and G Suite integration without email flow disruption. This is done by establishing a clear understanding of the specific enterprise, its employees and supply chain. The Abnormal Security Platform utilizes a data science approach to provide resources required for in-depth email detection, protection, and response. For analysis, it consolidates data across diverse channels into one platform, to provide multi-tenant and cross-platform protection.

The system co-exists with existing security tools without interference, leveraging the available information through the Microsoft APIs. It enhances and operates alongside traditional security capabilities provided by Microsoft EOP and ATP. Abnormal Security possesses additional offices in New York City and Salt Lake City, Utah.
