The solution is flexible and has its advantages and disadvantages. For example, a lot of things can be configurated exactly as you want it, but on the other hand, this makes it hard to automate and reuse it in other environments. 

I would recommend following them for the demos and webinars. There is a lot of cool stuff and features which you might not have known about. 

At this moment, we do not have any wishes. We have submitted a lot of feature requests in the past, but since there is a release every month, all our FRs and nice-to-haves have been implemented.

My advice would be to at least use this solution for service automation and access management because that's something you won't regret.

Overall, I would recommend HelloID for its ease of use and fair pricing.

My advice for anybody implementing this solution is to make use of a proof of concept.
