Abnormal Security

Abnormal Security provides a cloud email security platform that protects enterprises from targeted email attacks.

Abnormal protects organizations from targeted email attacks, including unknown threats that legacy solutions miss.

Abnormal Security was founded in 2018 by Evan Reiser, & Sanjay Jeyakumar. The company is headquartered in San Francisco, California.


The Abnormal Security platform provides unprecedented protection against targeted attacks by analyzing more sources of data than any other email security solution, including data beyond email. Abnormal Behavior Technology (ABX) uses this rich set of organization-specific data to uniquely drive the Abnormal Identity Model, the Abnormal Relationship Graph and Abnormal Content Analysis.


The Abnormal Security platform is currently deployed across a range of industries, including numerous Fortune 500 enterprises, many of whom helped shape the product to fit their most pressing security needs as they move to the cloud.


Abnormal Security raised $24M from a "Series A" financing on Nov 19, 2019. The round was led by Greylock.
