Security and cost efficiency: two major arguments for implementing Virtual Private Networking (VPN). Initially, VPN's were used to safely interconnect networks. IPsec standards were of prime impact to this technology, since it made VPN's manufactured by multiple vendors interoperable.
Due to increasing reliability and growing bandwidths on the internet, leased lines were replaced by VPN connections. Per location, only one reliable internet connection is needed in order to set up a VPN.
Encryption and remote VPN clients
Using the VPN client software, teleworkers and home office users needing full network functionality at their remote location, can set up very transparent network connections. Security is always key in these procedures: encryption based on 3DES or AES guarantees maximum privacy and token authentication is self-evident.
