Corelight Banks $75M for Network Monitoring Expansion Plans

Network detection and response play Corelight has raised a fresh $75 million funding round to speed up its global expansion ambitions.

The San Francisco-based Corelight said the Series D investment was led by Energy Impact Partners and brings the total raised to $160 million.

Previous investors Accel, General Catalyst, Insight Partners and Osage University Partners also joined the latest funding round.   Corelight also announced participation from anti-malware vendor CrowdStrike and Capital One Ventures.

The late-stage startup has developed a network traffic analysis platform based on the open-source Zeek (formerly Bro) framework and has positioned itself to capitalize on the demand for tools to find malicious activity in network logs.

The company’s sensors can be used to convert raw network traffic logs into structured data to pinpoint signs of network intrusion. 

Corelight chief executive Brian Dye sees the new cash infusion as validation for his company’s bet on the NDR (network detection and response) category.  "This is a powerful affirmation not only of the network detection and response category, but also of our open source heritage, data-centric approach, and commitment to customer success," Dye said in a statement.

Investor Shawn Cherian, a partner at EIP, said his firm was keen on supporting Corelight as it expands globally with an eye on the sustainable energy, manufacturing and other critical infrastructure sectors.

Corelight says its global customers include Fortune 500 companies, major government agencies, and large research universities.
