Proxies sit between an user and the web. It is used to intercept requests from a user, send web requests to the servers and forward the responses from the server to the user. It acts like a web filter or a firewall to enhance network security. Proxies also cache data to speed up the network connection.

The main purpose of using both proxies and VPN services is to hide the IP Address of the users or to prevent tracking bodies and individuals from identifying their location. For example, this may even be used to access certain sites that are not otherwise accessible in the user's country. A lot of VPN providers also provide proxy services apart from providing VPN services. You can also use many public proxy servers at little to no charge.

A Proxy server is a computer that sits between a client computer and the Internet and provides indirect network services to a client. A proxy server intercepts all client requests and provides responses from its cache or forwards the request to the real server.
