GreyNoise Intelligence operates in the computer and network security sector, providing real-time threat intelligence drawn from a large internet sensor network. The company aims to reduce alert fatigue for defenders by filtering out low-priority signals and giving security teams visibility into urgent, edge-related threats. Based in Washington, District of Columbia, GreyNoise is positioned as a mid-sized provider offering verifiable threat data that can inform incident response. Its core value lies in helping organizations focus on what matters most during threat investigations, rather than being overwhelmed by noise. Its target customers are security teams seeking to prioritize detection and response at the network edge, across various sectors. In April 2026, GreyNoise announced Project Swarm, a collective research initiative aimed at strengthening defenses at the network edge.
