What is the use of VPN technology? A Virtual Private Network is a private data network which is used for public telecommunication infrastructure, privacy maintenance through the use of a tunneling protocol and security procedures. A VPN can be used by private community / company with owned or leased lines which can only be used by one company. The purpose of VPN is to provide the facilities and capabilities to the company as private leased lines with much lower cost with the help of public infrastructure. Because of these advantages, companies are looking to use VPNs for both extranets and wide-area intranets.
