help GreyNoise Intelligence FAQ
Does GreyNoise analyze outbound traffic from my own network?
Not primarily. GreyNoise collects and classifies internet-wide scanning and attack activity observed by its sensor network, then provides context about the public IP addresses producing that traffic.
What do benign, malicious and unknown mean in GreyNoise?
These classifications describe GreyNoise's assessment of behavior associated with an observed internet-scanning IP. Benign may cover legitimate research or security services, malicious indicates harmful behavior, and unknown means the evidence does not support either conclusion.
What happened to GreyNoise RIOT?
RIOT was the name used for GreyNoise's dataset of common business-service IP addresses, such as infrastructure associated with Google or Slack. GreyNoise now refers to this area as Business Services Intelligence.
How is GreyNoise different from Shodan?
Shodan is commonly used to search for internet-exposed devices and services. GreyNoise instead emphasizes context about systems that are scanning or attacking the internet, helping analysts decide whether an alert reflects widespread background noise or targeted activity.
