VentureBeat reports that Abnormal Security has secured a $210 million investment from a Series C funding round, which will be allocated toward improving its cloud-native email security platform to better mitigate business email compromise and other email-based attacks.
Through the use of behavioral artificial intelligence, Abnormal Security's solution allows the detection and prevention of malicious actors and email messages.
"While our competitors leverage static rules and policies-based approaches that solely evaluate known bad indicators of compromise, Abnormal uses behavioral AI to baseline known good user behavior and precisely detect anomalies," said Abnormal Security CEO Evan Reiser.
Such technology is crucial as the rate of successful email-based phishing attacks has increased from 57% to 83% between 2020 and 2021.
"Modern attacks, including business email compromise, supply chain compromise, account takeovers and more, are difficult to detect. Because they typically contain no traditional indicators of compromise, they evade legacy email security solutions like the secure email gateway (SEG)," Reiser added.
