A VPN is a group of computers that are set up as a network on the internet and which you can access from your personal computer and/or mobile devices in order to protect yourself from eavesdropping. A VPN takes your private network and extends it across a public network, so that your IP address and data are encrypted and hidden.

Many people use VPNs today not only for security, but also in order to change the location of their computer so that they can watch their favorite TV shows from a foreign country or stay connected to a work network even when outside of the office. In addition, in countries where there is rigid state control of the internet, a VPN can help you sidestep the authorities and access banned websites, while also covering your virtual tracks.

VPNs, when chosen wisely and used correctly, present little risk. According to Forbes, the biggest threat that could come from using a VPN is simply using the wrong one. 

The rub is that it’s hard to adequately check a VPN provider’s claims, since by its very nature it’s operating through third-party sites. There will always be an element of faith required, which is where the benefits of consumer opinion come into play. If the company has a good reputation, a responsive support team, and a professional business model, it’s a safer bet than taking a gamble on free or unknown providers. This is why it’s important to do your research and find a provider you can trust.

It is better to choose a VPN service with a long history and a good reputation and read reviews, for example, on Reddit. Also, pay attention to such criteria:

• VPN jurisdiction ;
• The number of servers and countries;
• Negative precedents (for example, data leaks) associated with the provider;
• Support of all the latest encryption protocols and standards (OpenVPN, SSTP, L2TP / IPSec);
• Transparent and understandable user privacy policy;
• Fast connection;
• Favorable price-performance ratio.

Once you figure out what you will be using the VPN for, make a list of the important features and those you can refuse. It becomes much easier for you to decide which VPN to use. Things that your provider should have:

• Reliable encryption
• High speed
• Strong privacy policy
• Good performance
• No data caps on the Internet

A quality, safe VPN service will usually cost you $5-12 per month if you pay on a monthly basis, or as little as $30-50 per year if you’re willing to pay for a couple years up front.
