GreyNoise

GreyNoise provides threat intelligence focused on internet-wide scanning activity and the behavior of IP addresses observed across the public internet. Its technology helps security teams distinguish routine background scanning from activity that may represent targeted malicious behavior. GreyNoise classifies and enriches IP intelligence so analysts can reduce false positives and focus investigations on more relevant activity. This can be useful when security teams receive large numbers of alerts from internet-facing systems, firewalls, SIEM platforms or intrusion detection technologies. Its core value is adding context to network indicators so defenders can make faster decisions about whether activity represents meaningful risk. Organizations evaluating GreyNoise should consider data integrations, API access, enrichment requirements and how internet-scan intelligence fits into existing SOC workflows. It is particularly useful for security operations teams that need external context to prioritize alerts and separate benign internet background noise from potentially targeted scanning and reconnaissance.
