Surface Windows RT DOES NOT support Cisco IPSec VPNs
It doesn’t work for most Cisco VPN setups where the IT department has decided to use PSK authentication. Windows never natively supported the IPSec Identifier, or “Group Name” feature in Cisco VPNs, which would be the vast majority.
Apple's OS-X and iOS (Apple PC's and i-Devices such as iPhone, iPad, iPod etc. supports Cisco IPSec natively and has a field for Group Name, where Microsoft's VPN client does not have a field for Group Name thereby rendering it useless with Cisco IPSec VPNs.
On Windows RT, you cannot install the Cisco AnyConnect client.

That was the point of this thread. We knew this, but the reason it doesn't support VPNs is because MS has not released the APIs to do so. If you look a few posts up you'll see a forum admin now saying they are working on the APIs which means Cisco, Juniper, and others can create VPN clients for Windows RT.
