Locking down SSL VPN to specific devices
Hi,
I need to lockdown the SSL VPN to only specific (Corporate) devices.
I can see that there is an option in setting for this but I need to figure out how to go about his-

I would like to limit access to only corporate devices, maybe with an AD device group? (or similar). Also do I need a certificate?
Can anyone provide a link/documentation for this process as I am struggling to find anything decent with Google searching.
Thanks.
