GreyNoise tells security analysts what IP addresses they should and should not worry about.

Reduce noisy alerts to Increase analyst efficiency:

– Enrich your events and alerts with IP context

– Identify harmless IPs you can safely ignore

– Filter out harmless alerts in your SIEM or SOAR

– Eliminate false positive IOCs in your TIP

Uncover compromised devices

– Monitor IP addresses for scanning behavior

– Identify compromised devices in your network

– Identify compromised devices in your partners’ networks

Identify emerging threats

– Identify malicious IP addresses scanning the internet

– Differentiate between opportunistic scanning and targeted attacks

– Find out who is actively exploiting a CVE in the wild

Prioritize your patching


GreyNoise tells security analysts what not to worry about.

Eliminate noisy IP addresses from your alerts. GreyNoise helps you filter “internet noise” out of your alert stream, with context about noisy mass-internet scanners and common business services.We do this by capturing, analyzing and classifying data on IPs that scan the internet and saturate security tools with noise. This unique perspective allows you to confidently ignore irrelevant or harmless activity, creating more time to uncover and investigate true threats. GreyNoise intelligence is delivered through our SIEM, SOAR and TIP integrations, API, command-line tool, bulk data and web visualizer.

Unlock More Analyst Capacity
Events associated with IPs in Grey Noise can be de-prioritized, as they are likely associated with opportunistic internet scanning or harmless business services, not targeted threats. GreyNoise customers report reducing alert volumes by 25% and reducing manual research time by 20%, freeing up analysts to focus on true threats.

Stay on Top of Compromised Devices
If we see one of your devices scanning the internet, it’s likely compromised. GreyNoise’s alerts feature will notify analysts when an IP they care about shows up inour collection.

See Emerging Threats
GreyNoise sees IP addresses that exhibit device CVE-related device search, vulnerability check, and exploit behaviors, to identify IPs actively trying to exploit vulnerabilities in the wild.

How it Works
GreyNoise’s internet-wide sensor network passively collects packets from hundreds of thousands of IPs seen scanning the internet every day. GreyNoise analyzes and enriches this data to uncover source-IP behavior, methods and intent. GreyNoise continuously updates its IP dataset with this insight, making it available to analysts when queried.
