It is likely that the fact that both, VPN and proxy, are related to Internet security and share capabilities such as IP masking or location emulation, may lead to confusion.

In today´s post we will try to explain the main differences between these two concepts

PROXY:

As we explained in a previous entry, a proxy is a program or device that protects and improves access to a website. To do so, it creates a barrier between our local network and the Internet, thus avoiding direct communication between the client and the server. The objective of doing so is that no external user can see our IP and, consequently, identify us (only the IP of the proxy server will be visible).

The client makes a request, the proxy server receives the request and makes it on behalf of the client. Once it receives the information requested, it sends it back to the client. Consequently, any possible direct contact between the client and the server is avoided.

VPN:

On the other hand, the VPN (Virtual Private Network) on top of what has already been indicated, it encrypts the traffic that goes through it. In other words, while in the case of the proxy, either the ISP or the government (to name a few examples) or anyone who has access to the data stream, can access and see our traffic, in the case of the VPN this is not possible.

On the downside….

…While a proxy does not consume bandwidth, VPNs require a software program to be installed on the devices as well as a good hardware as both bandwidth consumption and processor consumption are considerably higher than in the case of proxies.
