Corelight

Corelight is an Open Network Detection and Response (NDR) platform created by the original developers of Zeek (formerly Bro). Corelight sensors passively monitor physical and cloud network traffic, transforming raw, high-volume network packets into compact, highly structured security logs that accelerate incident response investigations by up to 20x. By parsing over 400 network protocol attributes without capturing cumbersome PCAP payloads, Corelight drastically reduces SIEM ingestion and storage costs. It includes embedded Suricata signature scanning, encrypted traffic analysis for C2 beacons and unauthorized SSH channels, and Smart PCAP technology for selective packet retrieval.
