CrowdStrike Next-Gen SIEM Overview

Overview

Every internet-facing device is constantly bombarded by scanners, bots, and automated tools, generating thousands of false-positive alerts that overwhelm SOC teams and bury real threats.

The GreyNoise integration for CrowdStrike Next-Gen SIEM is delivered through a Falcon Foundry app that automates GreyNoise threat intelligence ingestion and lookup-file-based enrichment workflows. This allows teams to separate background internet noise from investigation-worthy activity directly inside Falcon.

Key Capabilities

  • Foundry App Deployment Model: GreyNoise Threat Intel is available in the Falcon Foundry App catalog.
  • Bulk Indicator Import Function: A logic function retrieves indicators from GreyNoise and uploads a CSV lookup file into Next-Gen SIEM.
  • Automated Daily Scheduler: A pre-built workflow runs daily at 03:00 UTC to refresh indicators.
  • Lookup-Driven Detection Support: Next-Gen SIEM searches can use match() against the GreyNoise lookup file to suppress noise and build high-fidelity detections.
