How can i distribute my App to specific people in an organization ?

We develop apps for a particular organization and our App has to be distributed within the organization(nearly 2500 users) and should not be visible to the public. We read about Volume Purchase Program and it seems pretty ok but we would like to know if this is the best or is there any better ways to do this. We develop apps for a particular organization and our App has to be distributed within the organization(nearly 2500 users) and should not be visible to the public.
