Corelight Secures $75 Million in Series D Funding Led by Energy Impact Partners with Participation from H.I.G. Growth Partners, CrowdStrike and Capital One Ventures

San Francisco, Calif. — Sept. 2, 2021 — 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). 

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.”

Lead investor EIP is a global investment platform backed by a large coalition of forward-looking utilities and industrial partners and focused on investing in cybersecurity, digital transformation, utility infrastructure and the broader energy transition. 

“EIP’s focus on critical infrastructure providers is highly aligned with both our mission and market traction,” said Dye. “Helping these institutions defend against increasingly sophisticated attackers is essential given their role in society and the economy.” 

“Corelight’s strong NDR technology, rooted in open source, has had a significant impact across industries and is rapidly becoming the de-facto standard for sophisticated defenders,” said Shawn Cherian, partner at EIP. “We look forward to supporting them as they expand their existing footprint within the sustainable energy, manufacturing and other critical infrastructure sectors.”
