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.

Based in the British Virgin Islands, ExpressVPN offers secure, encrypted and anonymous browsing for desktop and mobile devices. The VPN also works in an unprecedented number of locations globally — serving 94 countries. ExpressVPN enables you to access almost any content online, and you can purchase a subscription at $12.95 a month, $9.99 for six months or $8.32 for 12 months.

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.
