Hotspot Shield is a virtual private Network (VPN.) It is ranked among the best because it gives users a wide variety of options to choose from. When you sign up and download the software, you get a chance to choose between a free version, and a premium one. The difference is that the premium version allows you to choose from a variety of locations while the free one is limited. In addition to that, the premium version does not contain ads.
When using Hotspot Shield, you will have to download the executable file, and run it on your computer. This will allow you to choose a country where you want your data to be channeled through. For example, if you live outside the United States, but you want to access sites that are only open to this region, you can channel your browsing through the appropriate location, and you will not have any barriers.
