The most important benefit though is data security. Using a remote access VPN provides several advantages for businesses. How would a remote access VPN be useful to me and my business? The client software sets up the tunnelled connection to the NAS and manages the encryption required to keep the connection secure. Today most operating systems ship with built-in software which can connect to a remote access VPN, though some VPN services may require users to install a specific application instead. Users must also install client software on their devices to establish and maintain a connection to the VPN. To authenticate these credentials, the NAS uses either its own authentication process or a separate authentication server running on the network. In order to sign in to the VPN, the NAS requires that users provide valid credentials.

Users connect to the NAS over the internet in order to use a remote access VPN. The two main components of this type of VPN are a network access server (often called a NAS but not to be confused with network-attached storage) and VPN client software.Ī network access server could be a dedicated server or it might be a software application running on a shared server. This tunnel goes through the public internet but the data sent back and forth through it is protected by encryption and security protocols to help keep it private and secure.

A remote access VPN works by creating a virtual tunnel between an employee’s device and the company’s network.
