Our firm is partnered with a smaller firm that would like to outsource part of their IT infrastructure to us. Specifically, they would like to use the same document management software that we do, and they would like us to host it for them. They would use Terminal Services to access it.
Currently, each firm has a Cisco VPN network. We would be using dedicated servers for the task, not sharing what we already have. In that sense, it's basically co-location. Is there a way to provide them access to these servers without creating a mutual security risk?
It would be nice to include their servers in our nightly backup to tape, but I'm not against the idea of installing a new tape drive just for them if it makes the network configuration that much easier.
