What’s the difference between a VPN from a proxy?
Perhaps is the made of that both tools are widely used for masking the address IP, which has finished by make believe to the people that a Proxy and a VPN are it same.
A proxy is an intermediary between two computers that allows connect a client that is requesting resources to another server without this know to who goes directed the information. For example, when opened a web from the browser, are making a request to the server that hosts that site to send the information to our computer. Normally, without the intervention of a proxy, who sends the information can know our address IP and other types of data related directly with the client (US) that can reveal our identity.
When we use a proxy, this forms a barrier between us and the server which we request the data. Is the intermediary between your and a web site that instead of receiving your IP and your data, receives them from the proxy.
With a proxy acting as intermediary in your traffic of Internet, all the activity that carry to out will look like come of another side. A proxy can deceive to a web and make it believe that rather than be in a given country, are in another.
The only thing that makes a proxy server is to hide your IP. Usually they do not disintegrate any kind of additional identifier that may reveal your identity. This means that anyone with access to the data that you transmit through your network could spy your traffic: the Government, your ISP, anyone connected to the same network, Wi-Fi, malicious software in your browser, etc.
A VPN is a completely different matter. Yes, a VPN service also serves to mask your IP and do believe to a web site that you’re in another place, but the concept goes beyond just that.
A Virtual private network allows you to create a secure connection to another network and all traffic that passes through it is secured and protected. The VPN captures all traffic to the device where it is installed and contrary to a proxy that only acts as an intermediary between a single application, the VPN will encrypt everything that is transmitted from your computer.
It is as if creation of a completely private tunnel between your computer and a remote network which, in turn, will connect you to the rest of the Internet.
In conclusion, if the only thing you need is to hide your IP or make believe to a web site that you’re in another place, a Proxy you enough and too much. But if you are looking for security, privacy and anonymity, you need a VPN. The first do not have any cost of bandwidth, but the VPN if, and it is for this reason that you won’t get any offering you a completely free unlimited service. It is better encryption and more fast work, more expensive it will be.
