CrowdStrike

Cloudflare One can integrate with Crowdstrike to require that users connect to certain applications from managed devices. This service-to-service posture check uses the Cloudflare One Client to read endpoint data from Crowdstrike. Devices are identified by their serial numbers. If multiple devices have the same serial number, Cloudflare cannot accurately match a device with a third-party provider device. You must ensure that each of your devices has a unique serial number.

Device posture with Crowdstrike requires:

• Falcon Enterprise plan or above
• Crowdstrike agent is deployed on the device.

• Cloudflare One Client is deployed on the device. For a list of supported modes and operating systems, refer to Service providers.

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 Create API client and enter any name for the client.
4. Turn on the following API permissions:

   Scope	Permission
   Hosts	Read
   Zero Trust Assessment	Read

5. Select Create.
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.

1. In the Cloudflare dashboard , go to Zero Trust > Integrations > Service providers.
2. Select Add new.
3. Select Crowdstrike.
4. Enter any name for the provider. This name will be used throughout the dashboard to reference this connection.

5. Enter the Client ID and Client secret you noted down above.
6. In Rest API URL, enter your Base URL.
7. Enter your Customer ID.
8. Choose a Polling frequency for how often Cloudflare Zero Trust should query CrowdStrike for information.
9. Select Test and save.

1. In the Cloudflare dashboard , go to Zero Trust > Reusable components > Posture checks > Service provider checks.
2. Select Add a check.
3. Select the Crowdstrike provider.
4. Enter any name for the posture check.
5. Configure the attributes required for the device to pass the posture check.
6. Select Save.
7. To test, go to Insight > Logs > Posture logs and verify that the service provider posture check is returning the expected results.

You can now use this posture check in a device posture policy.
