If your main reason for having a VPN is just about having a bit more security on your computer or mobile device when using public Wi-Fi occasionally, the best free VPNs can do a decent enough job. This guide explains more about the dangers of using free VPNs and how to make sure you avoid those potentially dodgy ones.

Some of the sketchy free VPN apps bombard you with unwanted ads and very well may sell your data. There are literally hundreds of free VPNs available, and the truth is that most aren't that great. Virtual Private Networks (VPNs) are a great way to stay safe online, make your browsing more anonymous, protect your identity, and even view content or stream TV and movies from other regions. Typically, paid services offer much more than their free counterparts – but that isn't necessarily the case when it comes to VPNs. While downloading a free VPN is enticing, you may not be totally sure it's the right move to make – and for a good reason! There are plenty of upsides to using a free option over paying a premium, however, but there are also some sacrifices to be made as well.
