GreyNoise
Real-time network threat intelligence.
GreyNoise is a network threat intelligence platform built on first-hand scanning and exploitation data collected by a global sensor grid. It helps security teams detect active exploitation at the network edge, identify compromised devices that cannot run agents, and enrich or triage security alerts by separating targeted activity from mass-scanner noise.
The platform is organized around three pillars: Query, Observe, and Automate. Query supports IP and CVE lookups, GNQL search, bulk analysis of logs and PCAPs, CVE exploitation tracking, and customizable dashboards. Observe covers deployable sensors with emulation profiles, session forensics, and PCAP export. Automate provides feeds, alerts, dynamic blocklists, an API, and more than 80 integrations across SIEM, SOAR, TIP, firewall, and AI/agentic SOC tools, including Splunk, Google Security Operations, CrowdStrike, Microsoft Copilot for Security, and Anthropic Claude MCP.
GreyNoise offers separate products for enterprise and government use, plus GreyNoise Block, a configurable real-time blocklist product aimed at small and mid-sized businesses. Plans are available for viewing, and demos can be requested.
