Our organization too just deployed LoginTC. I think it's a great product for the price and very easy to setup. If your group is a large ISE environment you will find some challenges
with using LoginTC. In most ISE environments you will point your VPN appliance directly at your internal ISE so you can capture the RADIUS attributes. These attributes can then be used to build very granular policies based on posture etc. The problem with LoginTC is the above URL outlines pointing your VPN appliance directly to the internal LoginTC box first and then send a RADIUS request to ISE or other AD integrated AAA platform.
We have had a number of problems trying to use our ISE as originally intended for VPN along with LogonTC. The problem is getting ISE to make a "AND" RADIUS call to LoginTC after say an internal AD group has been queered. The CyberCor team said they were working to pass the same RADIUS attributes to ISE from the LoginTC box as ISE does natively but we have not seen that as of yet.
