Corelight has augmented the power of open-source Zeek with a suite of enterprise features that simplify enterprise deployments, making organizations spend more time on threat hunting and less time on system administration.

FREMONT, CA: San Francisco-based startup Corelight raised USD 50 million in a Series C funding round led by Insight Partners and their first capital investor Accel. The company aims to use the additional funds to accelerate investments towards product development, research, sales, and marketing to deliver new capabilities for network defense.

"Corelight recognizes that network data provide ground-truth evidence that security teams need to root out malicious activity inside their organizations," said Jeff Horing, co-founder and managing director at Insight Partners. "It is this unique data-centric approach that sets Corelight apart from other vendors in the security market space. As a result, we believe that Corelight has substantial opportunities to expand their portfolio and provide customers a fundamentally better foundation for their security programs. We look forward to partnering with the team as they build out that vision."

Corelight provides robust Network Traffic Analysis (NTA) solutions that transform network traffic into rich logs, extracted files, and security insights for more effective incident response, threat hunting, and forensics. The company was founded by Dr. Vern Paxson, Professor of Computer Science at UC Berkeley and Chief Scientist at Corelight, Robin Sommer, CTO, and Seth Hall, Chief Evangelist, to deliver network visibility solutions for cybersecurity built on an open-source framework called Zeek. Paxson began working on Zeek in 1995 when he was at the Lawrence Berkeley National Laboratory. Today, the software is widely recognized as the benchmark in Network and Systems Management (NSM) and NTA.

"What makes our data first security approach so powerful is the global community behind it," said Greg Bell, CEO of Corelight. "This community generously contributes to new detections, parsers, and other capabilities for the benefit of all defenders. In addition to helping Corelight accelerate commercial progress, the new investment will enable us to engage and serve our community at a higher level. Belief in this joint vision is a key driver for the partnership with Insight and Accel, two renowned and experienced firms."

Corelight has augmented the power of open-source Zeek with a suite of enterprise features that simplify enterprise deployments, making organizations spend more time on threat hunting and less time on system administration. These features include out-of-the-box enterprise integrations, distributed sensor management, and data tuning capabilities that can reduce the downstream SIEM costs by 30% or more. Since 2018, the company has more than doubled its size and raised total funding of USD 84 million from its previous rounds of funding.

"Corelight has quickly established itself as one of the foundational companies within network security with its passionate community of open source users and traction within some of the most discerning enterprise security teams globally," said John Locke, partner at Accel. "We're thrilled to double-down on our investment and excited about the growth ahead."
