We also know quite a lot about, and sometimes use, other products with clients, like Okta and Team (Elastic SSO). We have not really switched away from those products. But there is the fact that when given a project and asked for our recommendation and there is a choice, Ilex is the best solution that we can offer.  

One of the reasons why I point out that Ilex is an on-premises solution is that some clients want to have a fully secure environment and to have a SaaS offering that they will use for the SSO. In that case, Team would be a good potential option.  

Okta is maybe considered a bit more complex end-to-end. It is probably better applied in a situation where we are talking about very big projects where companies can spend months and a lot of hours putting their solution together.  The budget for implementing this product is extremely high. Because of all these reasons and by comparison, we almost always recommended Ilex as the best solution for the sake of prompt and efficient project deployment.
