Ease of use - it is so easy! We have been able do more than we thought possible without hiring an expensive consultant or architect! And best part -- they're always there if you need them!! Nothing that I dislike as much about this product but would say "it could be better". Overall great tool which makes deploying new applications faster & easier then ever before. I like how easy it is to use; there are so many features that you can configure as needed without having too much customization options available when using other solutions out their (such as ADFS). It's very expensive compared what we were paying before but at least they have good support if anything goes wrong - which has been rare since implementation! We've seen an increase from around 1% up until now where our user base went over 100%.
