SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rolling out endpoint detection and response across a fleet of endpoints is error-prone: sensors installed without a CID never connect, prevention policies left in detect-only mode never block malware, and macOS system extensions get silently blocked. This Skill provides a verified, step-by-step deployment workflow for CrowdStrike Falcon that avoids these common misconfigurations.

Core Features & Use Cases

  • Cross-platform sensor deployment: Silent installation commands for Windows (SCCM, Intune, GPO), Linux (deb/rpm with falconctl), and macOS (pkg with MDM system extension approval).
  • Policy configuration: Recommended prevention policy settings for machine learning, behavioral protection, exploit mitigation, and ransomware, with separate policies for workstations, servers, and critical infrastructure.
  • Validation and SIEM integration: Verification steps including RFM state checks, CsTestDetect test detections, and streaming telemetry to Splunk or Elastic via Falcon Event Streams and FDR.
  • Use Case: An IT administrator needs to onboard 500 Windows laptops to CrowdStrike via Intune, confirm each host reports Online with blocking prevention policies, and forward detections to the corporate Splunk instance.

Quick Start

Deploy the CrowdStrike Falcon sensor to my Windows endpoints via Intune and verify each host reports Online with prevention policies set to block.

Frequently Asked Questions about deploying-edr-agent-with-crowdstrike

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I deploy the CrowdStrike Falcon sensor on Windows?

Run the installer silently with WindowsSensor.exe /install /quiet /norestart CID=<YOUR_CID>, or deploy it through SCCM, Intune, or a GPO startup script. Always pass the CID during installation, since a sensor installed without it never connects to the Falcon cloud.

How do I install the CrowdStrike sensor on Linux?

Install the deb or rpm package, then register the sensor with sudo /opt/CrowdStrike/falconctl -s -f --cid=<YOUR_CID> and start falcon-sensor via systemctl. Verify connectivity with falconctl -g --rfm-state, which must return rfm-state=false.

Why is my CrowdStrike sensor installed but not detecting anything?

Common causes are prevention policies left in detect-only mode, the sensor running in Reduced Functionality Mode after an OS update, or the host inheriting the permissive default policy group. Confirm prevention toggles are set to Block and run CsTestDetect.exe to validate end-to-end detection.

Does CrowdStrike Falcon work on macOS Ventura and later?

Yes, but macOS requires explicit approval of the CrowdStrike system extension and Full Disk Access. Use an MDM PPPC profile to pre-approve these before deployment, otherwise the sensor installs but cannot function.

How do I send CrowdStrike detections to Splunk?

Create a Falcon API client with Event Streams read scope, then install the CrowdStrike Falcon Event Streams Technical Add-on from Splunkbase and configure it with your API client ID and secret. Events stream into a dedicated crowdstrike_events index.

When should I not use this CrowdStrike deployment workflow?

Do not use it for other EDR products like Carbon Black or SentinelOne, or for Falcon cloud workload protection, which requires cloud-specific deployment guides. It covers endpoint sensor deployment and policy configuration only.
