Why Corelight is a startup to watch

Corelight’s co-founders – Dr. Vern Paxson (chief scientist), Dr. Robin Sommer (Zeek project leader), and Seth Hall (chief evangelist) – originally worked together on the open-source Zeek security management platform. The three founded Corelight in 2013 to provide services built around Zeek. The startup’s CEO is Brian Dye, who previously served as EVP of products for McAfee and SVP of information security for Symantec. 

The company isn’t a newcomer, but its new financing is significant. In April 2024, Corelight closed a $150 million Series E round of funding, bringing its total raised to date to $309.2 million. Accel led the round. Cisco Investments and CrowdStrike Falcon Fund also participated.
