Corelight, provider of the industry's first open network detection and response (NDR) platform, today announced it has raised $75 million in Series D investment led by Energy Impact Partners (EIP).

Previous investors Accel, General Catalyst, Insight Partners and Osage University Partners also joined the round, as well as new investor H.I.G. Growth Partners, and strategic investment from Capital One Ventures, CrowdStrike Falcon Fund, and Gaingels. Corelight has raised a total of $160 million to date, with this latest round fueling acceleration of both global market presence and development of new data and cloud offerings.

Corelight is the fastest growing NDR platform, serving defenders in some of the world's largest financial institutions, retail and healthcare organizations, critical infrastructure providers and government agencies. Building on more than 20 years of open source development and community-driven insight, Corelight provides security teams with the world's best network evidence so they can close investigations quickly, even when incidents go back years.

"This latest investment 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," said Brian Dye, CEO of Corelight. "I am grateful for our investors' partnership as we help organizations around the world move to a data-driven security strategy."
