Corelight
Corelight is a network detection and response (NDR) vendor founded in 2013 by the creators of the open-source Zeek framework (formerly Bro). Its Open NDR Platform combines Zeek network evidence with Suricata intrusion detection, YARA file analysis, behavioral analytics, machine learning, and packet capture for threat detection, investigation, and incident response. It is positioned as an open-core product and integrates with SIEM and XDR tools, supporting on-premise appliances, virtual and software sensors, and cloud deployments across AWS, Azure, and GCP. Corelight remains a steward of the Zeek project.
Pros
