Abnormal Security is founded by veterans Evan Reiser and Sanjay Jeyakumar , both veterans of the advertising technology industry.Evan Reiser and Sanjay Jeyakumar do not come from cybersecurity backgrounds. The pair linked up at TellApart, the advertising technology startup that was sold to Twitter for $479 million in the social media giant’s largest acquisition to date.
“A lot of people in security come from a threat intelligence background with antivirus and antispam, where you’re trying to recognize signals when they come in,” says Reiser, who is CEO. “For us, it’s a different kind of mental model. It turns out this style of approach is very effective for this next generation of cybersecurity attacks, which are about impersonation.”
The software uses artificial intelligence and machine learning to analyze the data in an email. Abnormal then determines, in Reiser's words:"What are the chances this is normal behavior in the organization?"Just as marketing technology looks at a user’s data to serve up suggestions or ads based on their clicks and interests, Abnormal Security uses machine learning to learn the behavior of an organization’s email account holders.
