Some of the most valuable features of Jumpcloud have been the use of the policies. They have been very helpful. There are modules in there for policies where you can create your own which indirectly are GPOs similar to what you have for Microsoft environments, however, they are only doing registry changes. They are very powerful and useful. Additionally, having your directory and SSO in one spot is another thing that they provide in application management. Adding, removing, and updating applications are in one place for desktop administration.
