What Is a VPN, and Why You Need One

Take a step back and consider how much of your life is transmitted over the inherently insecure internet. Do you feel a creeping sense of dread? That’s entirely reasonable, considering the forces arrayed against your privacy. One of the best ways to secure your data is to use a virtual private network (VPN), which also provides some control over how you’re identified online. 

What Is a VPN and How Does It Work?

Simply put, a VPN creates a virtual encrypted tunnel between you and a remote server operated by a VPN service. All your internet traffic is routed through this tunnel, so your data is secure from prying eyes. Best of all, your computer appears to have the IP address of the VPN server, masking your identity and location.

What a VPN Won’t Do

We should note that there are multiple ways your behavior can be tracked online — even with a VPN, things like cookies allow web services (Amazon, Google, Facebook, and so on) to track your internet usage even after you’ve left their sites (here’s a handy guide to pruning cookies on your browser.)

When the internet was first being pieced together, there wasn’t much thought given to security or privacy. At first it was just a bunch of shared computers at research institutions, and computing power so limited that any encryption could have made things extremely difficult. If anything, the focus was on openness, not defense.
