Corelight and GreyNoise Threat Detection Solution

This document is a technical report detailing the joint solution provided by Corelight and GreyNoise for enhancing threat detection in Security Operations Centers (SOCs). It outlines the challenges faced by SOCs, including the overwhelming volume of benign alerts and the rapid evolution of threats exploiting zero-day vulnerabilities. The report describes how Corelight's Open NDR Platform captures detailed network traffic evidence, which is then enriched with threat intelligence from GreyNoise. This two-layered defense system allows security teams to identify both known and novel threats with precision. The integration of this solution into CrowdStrike’s Falcon Next-Gen SIEM provides analysts with comprehensive visibility, enabling them to differentiate between benign noise and actual threats. A use case involving the F5 BIG-IP breach illustrates how the joint solution allows SOCs to detect and respond to threats before official indicators of compromise are available, thereby preventing potential breaches.
