What is a VPN?
VPN creates a secure tunnel between your PC and the internet. You connect to a VPN server, which can be located in the United States or a foreign country—say, France or Japan. Your web traffic then goes through that server to make it appear as though you’re browsing from that server’s location, and not from your actual location.
When you’re using a VPN, it’s difficult for others to snoop on your web-browsing activity. Only you, the VPN service, and the website you’re visiting will know what you’re up to. 
A VPN can be a great response to a variety of concerns, such as online privacy, anonymity, greater security on public Wi-Fi, and, of course, spoofing locations.
While a VPN can aid privacy and anonymity, I wouldn’t recommend fomenting the next great political revolution by relying solely on a VPN. Some security experts argue that a commercial VPN is better than a free proxy such as the TOR network for political activity, but a VPN is only part of the solution. To become an internet phantom (or as close as you can realistically get to one), it takes a lot more than a $7 monthly subscription to a VPN.

If you want a VPN for political reasons, this article cannot help. But there are other places you can turn to online such as the Electronic Frontier Foundation.

Moving on to less serious topics, a VPN is an excellent choice for staying secure while using Wi-Fi at the airport or your local café. Hackers sitting on public Wi-Fi can try to hack your PC, but a VPN makes that task much harder.

Finally, you may want a VPN to spoof your location to download content you shouldn’t have access to, but this too has limits. A VPN used to be the go-to solution to watch U.S. Netflix overseas. That changed in 2016 when Netflix opened up to almost every country on Earth. Since then, the company has invested a lot in detecting and blocking VPN users. Even people using a VPN inside their own country will be blocked by Netflix if detected.

There are VPNs that can fool Netflix, but they are rare and there are no guarantees these services will outsmart Netflix forever.

Beyond Netflix, a VPN can help to download an Android app that is only available on a foreign version of Google Play, or stream content from regionally restricted services such as the UK-bound BBC iPlayer or Pandora.VPN download
