CrowdStrike

Device posture with CrowdStrike requires the CrowdStrike agent and the Cloudflare WARP client to be deployed on your devices. Our service-to-service posture check identifies devices based on their serial numbers.

​​ Set up CrowdStrike as a service provider

​​ 1. Obtain CrowdStrike settings

The following CrowdStrike values are needed to set up the CrowdStrike posture check:

• Client ID
• Client Secret
• Base URL
• Customer ID

To retrieve those values:

1. Log in to your Falcon Dashboard.

2. Go to Support and resources > API Clients and Keys.

3. Select Add new API client and enter any name for the client.

4. Enable the Read API Scope for Zero Trust Assessment, Hosts, Detections, Event Streams, and User Management.

5. Select Add.

6. Copy the Client ID, Client Secret, and Base URL to a safe place.

7. Go to Host setup and management > Sensor downloads and copy your Customer ID.

8. Get an auth token from your CrowdStrike API endpoint:

   
   curl -X POST "<BASE_URL>/oauth2/token" \
       -H "accept: application/json" \
       -H "Content-Type: application/x-www-form-urlencoded" \
       -d "client_id=<CLIENT_ID>&client_secret=<CLIENT_SECRET>"
   

   This POST request authorizes Cloudflare Zero Trust to add CrowdStrike as a service provider. For more information, refer to the Crowdstrike auth token documentation Open external link .
