VPN or Virtual Private Network is used to improve the connections to a public network like the internet and helps to make it more unrestricted. A VPN Service helps to remove the bans and restrictions that are applied on the web in particular countries or geographical areas. They are mainly WAN or point to point connections that connect to the internet and sends data using various encryption methods. Here the user is provided with a forged IP which helps to hide his identity. At the same time the user will have the impression of using a private connection. A VPN service is used by the IT firms mainly for two reasons. Firstly it helps to create anonymity in the internet usage. Since the original IP is hidden it becomes practically difficult to identify what you are doing online. Another advantage is that it lifts many injunctions that are applied in internet usage. Many of the VPN service providers give you the fake IP of a foreign country while authentication. This will help you to access even the banned websites. Initially companies like AT&T provided VPN like products that typically used dial up modems and leased lines. They were not fast and were very costly. So they were replaced by high bandwidth VPN systems which used optical fibers and DSL. Since a VPN allows geographically separate offices to work closely as one the new fast systems become wildly popular. Now there are many large and small VPN service providers and their services will allow your company executives to work remotely.
