The initial setup was straightforward because the on-premises model has a virtual server. It takes 20 minutes or less to bring it up. However, the configuration including the setting of policies, whitelisting, blacklisting, etc., that takes a lot of time. 

You only need one staff member for maintenance.

The initial setup was straightforward because we actually have a system that automatically deploys. So that works really well.

The initial setup was quite complex. Deployment took more than three weeks.
