About
Corelight is a cybersecurity company founded in 2013 by Vern Paxson, Robin Sommer, and Seth Hall and headquartered in San Francisco, California. The company commercializes and extends Zeek (formerly known as Bro), an open-source network analysis framework developed by co-founder Vern Paxson at Lawrence Berkeley National Laboratory that has become the de facto standard for high-fidelity network traffic analysis in enterprise and government security operations. Corelight's platform provides network detection and response (NDR) capabilities — deep packet inspection, protocol parsing, and threat detection across network traffic — giving security teams comprehensive visibility into what is moving across their networks, which is critical for detecting threats that evade endpoint-based tools.
