For the POV process, we strongly encourage customers to use the SaaS offering. The Contrast UI is exactly the same when used in a SaaS environment or as an Enterprise On-Premises (EOP) deployment.

For organizations who have strict requirements around using on-premises software, Enterprise On-Premises is a deployment option that we offer for meeting customer needs, but there are some drawbacks with this deployment model.
