I like that it's easy for users who are not security experts but do have some knowledge about computers or networking devices (like me) so they can understand what is being said without having any technical background at all.
It was fairly simple once we were familiar with how everything worked together. The user interface could be improved though - there should definitely be an easier way than using multiple windows/tabs just because one thing isn't working right! We've been able to identify our network infrastructure more easily now which has helped us better manage access rights across different parts of campus.
