Abnormal Security, a San Francisco, CA-based cloud email security platform, raised $24M in Series A funding.
The round was led by Greylock Partners.
Founded in 2018 by CEO Evan Reiser and CTO Sanjay Jeyakumar, Abnormal Security provides a cloud email security platform that protects organizations from the most sophisticated, targeted email attacks, including unknown threats that existing solutions miss. Through composite analysis of identity, relationships and email content, the platform stops attacks that lead to account takeover, financial damage and organizational mistrust.
Abnormal Behavior Technology (ABX) uses a set of organization-specific data to drive the Abnormal Identity Model, the Abnormal Relationship Graph and Abnormal Content Analysis.
The Abnormal Identity Model builds profiles of employees and third parties such as vendors and customers using hundreds of attributes extracted from dozens of data sources.
The Abnormal Relationship Graph understands the strength of relationships by evaluating the cadence, topics and tone of communication in addition to the frequency.
Abnormal Content Analysis uses a variety of techniques such as computer vision and natural language processing to understand the context and meaning of communications.
The platform is currently deployed across a range of industries, including numerous Fortune 500 enterprises.
