CorelightvsExabeam

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.

Exabeam is an AI-driven security operations and Next-Gen SIEM platform that empowers security teams to detect, investigate, and respond to advanced cyber threats, credential misuse, and insider attacks. Built around market-leading User and Entity Behavior Analytics (UEBA), Exabeam establishes baseline behavioral norms for every user, machine, and credential across an enterprise. When deviations from normal behavior occur, Exabeam automatically stitches disparate log events into Smart Timelines—chronological, pre-parsed visual narratives that detail user activity across sessions. This automation allows security analysts to investigate credential compromises, lateral movement, and data exfiltration in minutes rather than days.
