Corelight secures $25 million in Series B funding led by General Catalyst

Corelight announced it has secured an additional $25 million in Series B financing led by General Catalyst.

With this additional round of capital, the company will accelerate investments in product development, research, sales, and marketing with the aim of delivering new capabilities for network defense.

“The question today isn’t if the bad guys have access to your network – they do – but instead, what they’ve done once they’ve gotten in,” said Steve Herrod, managing director at General Catalyst, and former CTO of VMware.

“Corelight helps security professionals get to breach impact and remediation faster. Their network intelligence approach is a strong complement to GC’s security portfolio and is already demonstrating exceptional product market fit. We’re privileged to be partnering with them today.”

“This investment opens a new chapter in our history, and we’re happy to have found another exceptional board member in Steve Herrod,” said Greg Bell, CEO of Corelight.

“Over the past year we’ve greatly expanded our product line and enjoyed significant commercial traction. More organizations are turning to Corelight to provide detailed, real-time data for network defense. This new investment will help us address their needs faster and more comprehensively. We are just getting started.”

Corelight was founded by Dr. Vern Paxson (a Professor of Computer Science at UC Berkeley and Chief Scientist at Corelight), Dr. Robin Sommer (CTO) and Seth Hall (Chief Evangelist) to deliver network visibility solutions for cybersecurity built on an open source framework called Bro.

Paxson began developing Bro in 1995 when he was working at the Lawrence Berkeley National Laboratory (LBNL); the name refers to George Orwell’s “Big Brother” as it signals the need for operators of network monitoring to remain mindful of their users’ rights and privacy.

Corelight has merged the power of Bro with a suite of enterprise features that make Bro easier to deploy in enterprise environments, like an intuitive management UI, native NIC shunting, sensor health metrics, and automated data export to Splunk, Elastic, Kafka, Syslog, S3, and more.

Corelight plans to continue to expand internationally with increased investment in global sales infrastructure and build out additional strategic partner alliances domestically and abroad.

This news comes on the heels of the company’s recent launch of the Corelight Virtual Sensor which enables monitoring and allows organizations to flexibly monitor traffic anywhere virtual infrastructure is deployed at speeds up to 2 Gbps and is scalable across four reference configurations for VMware.
