There are 2 different types of proxies, one that involves your machines and other is a web based proxy. But despite that both of them share the same outcome, to browse the web in a safer way.
As I said that In any of the cases a proxy works the same way it will allow you to secure you privacy such as you IP address but also give you access to certain places that may have been block to your networks. I am talking about your work place, schools, libraries and so on.
With the help of a proxy you will able to unblock those websites that have been blocked with your network’s provider. As this will enable you to surf the internet using another server with another IP address.
So if you are blocked in any web address is not the end of the world because you can navigate still using a proxy and not only that, by using a web based proxy you will browse safer because then you do not require to install any anti spyware or anti virus on your system, because you are surfing with a proxy and the content is filtered so no harm can do to your machine.
So here you go: the advantage of using a proxy or proxy based website. And if you are interested in a web proxy, one I like to use is proxify.com It’s fast, free, and it also has some other feature such as testing you internet speed and many other cool tools which are also free.
