In the Falcon Console, click the main menu icon in the upper-left side of the screen. Then, click the Host Setup and Management category. Finally, click Sensor Downloads under the “Deploy” category.

Find the Linux sensor, and click the download button to download the latest sensor to your machine.

Find Your Customer ID
