For the purpose of the current document, a VPN is a product with digital elements that provides access to a restricted-use logical computer network that is constructed from the system resources of a physical or virtual network, including cases where that product provides access from a restricted-use logical computer network to a public network.

As a holistic product, a Virtual Private Network includes, at minimum, VPN software capable of establishing a secure encrypted tunnel between two or more devices. VPN products also provide management capabilities to network administrators: user and group management, access control, logging and monitoring.
