Key Characteristics
Remote Access VPN is a type of VPN that allows individual users to connect securely to a private network from a remote location over the public internet. This technology enables employees, contractors, and other authorized users to access corporate resources such as files, applications, and internal systems as if they were physically connected to the company's local network.
Remote Access VPNs typically use client software installed on the user's device that establishes an encrypted tunnel to a VPN server located within the corporate network. The connection authenticates the user and encrypts all data transmitted between the remote device and the private network.
