Corelight raises $50 million to monitor networks for intruders

Corelight, a San Francisco-based startup developing a network traffic analysis platform for cybersecurity, today announced that it has raised $50 million in a series C funding round led by Insight Partners and Accel. Belief in this joint vision is a key driver for the partnership with Insight and Accel, two renowned and experienced firms.” Corelight got its start in 2013, when Dr. Vern Paxson — a professor of computer science at the University of California, Berkeley — teamed up with Robin Sommer and Seth Hall to build a network visibility solution atop an open source framework called Zeek (formerly Bro). Corelight offers a suite of enterprise-managed features supporting Zeek, including out-of-the-box integrations, distributed management, and data tuning capabilities that transform undifferentiated network traffic into rich logs, extracted files, and security insights. Logs from Corelight’s sensors — which are available in physical, virtual, and cloud-based form factors — can be seamlessly exported to data tools like Splunk, Elastic, QRadar, and Spark in minutes. “Corelight recognizes that network data provides ground truth evidence that security teams need to root out malicious activity inside their organizations,” said Insight Partners cofounder and managing director Jeff Horing.
