How to set it up

1

Set the access mode (Windows only)

On Windows, choose the USB storage access mode from the dropdown:
  • Block — prevents all removable storage devices from connecting.
2

Select targeting

Choose which devices to apply the control to: all devices, specific device groups, or a custom target.

​
Modifying or removing the control

Disable the control from the profile settings. Disabling stops enforcement but does not remove existing configurations from devices.

​
How it works

​
macOS

Primo pushes an MDM restriction that blocks removable storage devices from mounting. No additional configuration is required.

​
Windows

Primo deploys an MDM policy that blocks the installation and use of removable storage devices based on the configured access mode. Blocked devices appear in Device Manager and users see a notification that the device cannot be used.
