Corelight Open NDR Platform
By Corelight
A commercial network detection platform built around the open-source Zeek framework its founders created, generating rich structured connection and protocol logs rather than raw packet dumps. Bundles a Suricata signature engine and JA3/JA3S encrypted-traffic fingerprinting alongside Zeek's native logging.

- Sees lateral movement between internal hosts, not just traffic crossing the perimeter.
- Packet capture & forensics — supported
- Stores full or metadata-level packet history for post-incident investigation.
- Threat intelligence integration — supported
- Enriches detections with known-bad IPs, domains, and indicators from feeds.
- Inline blocking (IPS mode) — not supported
