Device Control

Can Cortex XDR prevent the use of other USB devices other than Disk Drives, CD-Rom Drives, and Floppy Disk Drives? If one of my users plugs in a printer, can that be denied? Can the same be done with SD cards?

Hi @efasoformoso-


The device control feature is designed to enforce USB-connected devices.  If the device is connected via an external SD reader, you may be able to block - I would need to test to verify.  You can also block execution from an SD-card by leveraging a restriction profile regardless if the reader is embedded or external.  

You should be able to block the printer.  Here is a list of Windows portable device classes (provided by Microsoft) that Cortex XDR can block.


Additionally, you are able to create custom device classes. 


Hope this helps.

Thank you for the response!

Can printers be disallowed on macOS too?

Hi @efasoformoso-


At the current time, this is a Windows-only feature.  It is based on the device class for Windows.  macOS is limited to drives.  See doc here:
