VPN services enable you to browse anonymously and get access to websites / web services which are restricted in your network. Web Proxies also do this but they can be really dangerous as they can spy on your content. Also most of the web proxies block java scripts and dynamic content. Key requirements to use any VPN service are:
Bypass local network firewall:
Most of the school/colleges and offices have their firewall block sites like Gmail, Facebook, Youtube, Twitter etc. Access to these sites can be gained though using a VPN. (Caution: If use of such VPN clients is restricted by policy in your network, do it at your own risk).
Bypass geographical restrictions:
There are many websites/webservices which are available in a particular geography only. As an example, Hulu or Pandora are not available in India (or outside US). These webservices impose restriction at IP level so that people from outside the available region are unable to use it. Using VPN you can get access to such websites/services.
Anonymous Web Surfing:
Many a times a user may not want to reveal his identity while browsing. A user may want to interact in a sensitive debate without revealing his / her identity. He may also want to use P2P file sharing without sharing his details.
