The benefit of using VPN for remote access to the company network includes allowing users to send print jobs to printers located in the office or to work on files stored on the network drive. This allows users both offices access to the same shared storage drives. For instance, a business with two offices would use a VPN to connect the two local networks together. Most businesses use VPN for two reasons: one to allow remote employees access to the office network and two to connect several networks across multiple offices together. Two computers connected via VPN appear as being on the same network and can share files as if they were connected via network switch. The connected computers comprise a virtual network, with functionality mirroring that of a physical network.
