Control which Forticlient apps are allowed to connect?

Hi All,

I wondered if there was a way to control which Forticlient applications are allowed to connect to to SSL-VPN via Fortigate? We use Forticlient on all Windows devices, but we've recently found that if a user with enough knowledge installs the app on say an Apple or Android mobile device, they can connect that device.

Is there a way of restricting so only Windows versions of Forticlient is allowed to connect?

Thanks in advance,

Alex
