Frequently Asked Questions (FAQ)
When will this feature be available?
This device control feature is currently available only in the Preview package subscription.
What will the device type be shown as in a Device Control policy?
'Media Devices (10.3.2 and above)' will be shown as a new device Type in your Device Control policy Configuration tab.
If I change the Status for 'Media Devices (10.3.2 and above)' to Blocked what will happen on older SAV endpoints?
Any configuration setup for this device type will only function on endpoints with SAV 10.3.2 and above, all other versions will ignore this setting. The type of device listed will be visible to all customers regardless of the subscribed packages or Sophos console version.
Can I control files being sent to PTP/MTP devices over WiFi (Samsung Kies / iTunes)?
Since there is no physical connection to the computer, device control cannot control the transfer of data from devices connecting over WiFi. Sophos Client Firewall can be configured to block such transfers.
Why has my 'all-in-one scanner'/webcam/printer device been blocked?
In order to provide complete coverage on all platforms some additional devices may be unexpectedly blocked. This occurs when the device connected to the computer presents itself as an 'Imaging device', this device type is used by some popular smart phones (e.g. Apple iPhone). You use the 'Add exemption' button in your Device Control policy to allow these devices to operate fully.
