Corelight

Corelight's Open Network Detection and Response (NDR) Platform improves network detection coverage, accelerates incident response, and reduces operational costs by consolidating NDR, intrusion detection (IDS), and PCAP functionality in a single solution and by providing security analysts with machine learning-assisted investigations and one-click-pivots from prioritized alerts to the evidence needed to investigate and remediate them. Network Detection and Response platforms monitor and analyze network traffic, delivering telemetry into existing SIEM, XDR, or SaaS-based solutions. Corelight’s platform is unique because our detections and visibility engineering are community driven—with continuous content creation from Zeek®, Suricata IDS, and other Intel communities. And our integration with CrowdStrike XDR enables cross platform (EDR+NDR) analytics. This provides you with the most complete network visibility, powerful analytics, and threat hunting capabilities, and accelerates investigation across your entire kill chain. Corelight also delivers a comprehensive suite of network security analytics that help organizations identify more than 75 adversarial TTPs across the MITRE ATT&CK® spectrum including Exfiltration, Command and Control (C2), and Lateral Movement. These detections reveal known and unknown threats via hundreds of unique insights and alerts across machine learning, behavioral analysis, and signature-based approaches.
