I like that it can be used with any type of device, not just Cisco devices.
The interface could use some work as well but this software has been able to get me through all my issues so far. It would help if there was more information about your network in general available when you are configuring things; however, we have had no problems using it thus far! We were looking into having our own VPN setup instead of relying completely upon public ones such as Google or Facebook. This helped us keep control over who accesses what resources while also providing additional privacy benefits since they cannot see where their data goes once inside the system.
