About

GreyNoise operates as a specialized threat intelligence platform that analyzes internet background noise to help security professionals distinguish between malicious attacks and benign scanning activity. The platform collects and categorizes data from millions of internet scanners, bots, and automated systems that continuously probe networks worldwide.

The platform's core technology focuses on internet noise classification, automatically identifying whether scanning activity represents legitimate research, security testing, or genuine threats. GreyNoise maintains extensive databases of known scanner behaviors, IP reputation data, and scanning patterns to provide context-rich intelligence about internet traffic.

Key features include real-time IP reputation lookups, historical scanning data analysis, and comprehensive tagging systems that categorize scanner types and intentions. The platform offers API access for integration with existing security tools, SIEM platforms, and threat hunting workflows. Security teams can query specific IP addresses to understand their scanning history and behavioral patterns.

GreyNoise Visualizer provides interactive dashboards and search capabilities that allow analysts to explore internet scanning trends and identify emerging threats. The platform tracks scanning campaigns, botnet activity, and research projects to help organizations prioritize their security responses effectively.

The service proves particularly valuable for threat hunters, SOC analysts, and incident response teams who need to filter out noise from legitimate security alerts. Organizations use GreyNoise to reduce false positives in their security monitoring systems and focus resources on actual threats rather than benign scanning activity.

Security researchers and academic institutions leverage the platform's comprehensive internet scanning data for threat research and cybersecurity studies. The platform's ability to provide historical context about scanner behavior helps analysts understand attack patterns and predict potential threats.

GreyNoise integrates with popular security tools including Splunk, IBM QRadar, and various SOAR platforms. The company offers both community and enterprise versions of its service, with the enterprise tier providing enhanced features for large-scale security operations and advanced threat intelligence requirements.
