Most people probably aren't familiar with a VPN, nor know what it actually does. Yes, a VPN allows you to stream Netflix from different countries. It's also a privacy and security tool that encrypts users' web traffic and masks their IP addresses. This means that whether you're trying to watch YouTube abroad or looking for some extra security when in Starbucks, a VPN can be your best friend for secure, anonymous browsing.

However, finding a reliable VPN can be a difficult task with so many out there. Here are some of our favorites to consider if you're planning to travel, or even do some holiday shopping while enjoying your favorite coffee blend.

NordVPN

NordVPN

NordVPN covers desktop and mobile devices, with manual setup available for wireless routers, NAS devices and other platforms. Based in Panama, NordVPN is arguably one of the most affordable paid-for VPNs, and currently has a deal for $2.99 a month for its 3-year plan, along with its standard $6.99 for 12-months and $11.99 per month options.

These VPNs aren't necessarily required for you to be protected. But if you use a lot of public Wi-Fi or if you're abroad, they might be good for you to keep in your back pocket.
