What is a Private Network? 

A private network connects a controlled number of computers and is usually local to the physical devices. This network is completely segregated from the public network. Data that moves across a private network is not in the wild. It is not visible to anyone outside the private network and is untouchable by any public means while in transit. Because this data is sent across a separate network, there’s no need for encryption while in transit. The data is protected based on the extremely-limited access.
