GreyNoise Intelligence Is Available Across the CrowdStrike Falcon Platform

Every SOC analyst knows the feeling: another morning, another queue of hundreds of alerts, and the gnawing question of which ones actually matter. The volume of internet background noise — automated scanners, research probes, vulnerability crawlers — hasn’t slowed down. If anything, it’s accelerating. And as adversaries adopt AI to move faster, the cost of chasing the wrong signals isn’t just frustrating — it’s dangerous.

That’s the problem GreyNoise was built to address. We operate one of the largest passive sensor networks on the internet — more than 5,000 sensors across 80 countries, analyzing up to one billion sessions per day and tracking over 50 million IPs. That scale lets us classify internet-wide scanning and reconnaissance activity with confidence: which IPs are known benign scanners, which are actively malicious, and which are unknown — meaning we haven’t observed them scanning the internet indiscriminately.

That classification data is now available across the CrowdStrike Falcon platform — in Next-Gen SIEM, Falcon Fusion SOAR, and the agentic workflows that are defining the next era of security operations.

GreyNoise Intelligence Across CrowdStrike Falcon

For teams running Falcon, GreyNoise intelligence is operationalized across three integrated capabilities — inline investigation context in Next-Gen SIEM, automated enrichment and response in Falcon Fusion SOAR, and agentic collaboration through Charlotte AI.

The GreyNoise Foundry App — available directly on the CrowdStrike Marketplace — is the operational core of the integration. Once installed, it automatically imports a fresh GreyNoise indicator lookup file into Next-Gen SIEM every day. No manual feed management. No stale data.
