Corelight bags $75Mn in Series D funding to expand global NDR offerings

Corelight, a San Francisco-based startup that reportedly offers the first open NDR (network detection and response) solution in the industry, has secured USD 75 million in a Series D funding round led by Energy Impact Partners. 

The investment round witnessed the participation of Capital One Ventures, Gaingels, and Crowdstrike Falcon Fund.

Notably, Corelight’s total raised capital year-to-date stands at USD 160 million, following a USD 50 million Series C bagged in October’19, USD 25 million in Series B in September 2018, and USD 9.2 million Series A funds in July 2017.  

According to Brian Dye, CEO, Corelight, the company has emerged as one of the rapidly- rising NDR players at scale and is focusing on investing in growth, and expects to raise additional capital in the coming times.

With the latest raised capital, Corelight aims at accelerating its global market presence to develop cloud-based offerings and new data, Mr. Dye added.

Corelight was incorporated in the year 2013 by Dr. Vern Paxson- a computer science professor at the University of California together with Robin Sommer and Seth Hall to develop a network visibility technology on top of an open-source solution known as Zeek. Some of the direct competitors of Corelight include McAfee and FireEye.

Dr. Paxson began developing Zeek in the year 1995 while working at Lawrence Berkeley National Laboratory.

The software is referred to as the gold standard in network traffic analysis and network security monitoring and has been adopted by several organizations across the globe such as the U.S. Department of Energy, several agencies in the U.S., and research universities such as Stanford, Ohio State, and  Indiana University.     

In August’21, Corelight announced a partnership with Carahsoft Technology Corp. to offer open NDR solutions to the Department of Defense, Coast Guard, and Intelligence Community. The blanket purchase agreement has been signed for a period of ten years through July 2029.
