Abnormal Security emerged from stealth mode on Tuesday with $24 million in funding and the launch of its cloud email security platform.
The San Francisco-based firm raised the money in a Series A funding round led by Greylock Partners, which connected Abnormal Security with over 50 CIOs and CISOs from Fortune 500 companies in order to get their input while developing its platform.
The Abnormal Security email security platform is now generally available and it has already been used by some of these Fortune 500 companies. The solution is designed to protect organizations against targeted email attacks, such as business email compromise (BEC), email account compromise, and internal email attacks.
The platform relies on what the company calls Abnormal Behavior Technology (ABX), which uses data from various sources to drive the Abnormal Identity Model, the Abnormal Relationship Graph and Abnormal Content Analysis.
These components are designed to build profiles for employees, vendors and customers; evaluate the frequency, cadence, topic and tone of communications; and understand the context and meaning of emails.
Abnormal Security says the solution can be easily integrated with Office 365 and G Suite without requiring any special configuration and without causing delays to email delivery.
The company was founded last year by Evan Reiser, who serves as CEO, and Sanjay Jeyakumar, who serves as CTO. Reiser and Jeyakumar have contributed to developing and running Twitter’s ad engine. The Abnormal Security team also includes people who previously worked for Twitter, Google, Amazon, Palo Alto Networks, Proofpoint, FireEye and Duo Security.
