I looked into using their Enterprise product for my employer about 6 months ago. It seemed to be a nice product but was shockingly expensive compared to its counterparts in the space. Also, when they say "enterprise" they meant it. They are targeting large companies with 10s of thousands of employees; our 300 user company was really on the low side. Of course this is a pretty new product and this type of thing tells me that it's not quite mature yet and probably difficult to support.
