What is a VPN?

Let's begin with defining the acronym:

VPN = Virtual Private Network

The easiest way to explain what a VPN is - without getting overly technical - is to explain how one works.

A VPN creates an encrypted connection between your device and the VPN server. This is frequently and commonly referred to as the "tunnel." VPNs were originally designed to securely connect two physically separate networks; as such, they weren't necessarily designed with user privacy in mind.

Assuming the encryption protocol of the tunnel is up-to-par, there are very few methods which can directly penetrate the VPN.

Essentially, barring any leaks, the information that passes through this tunnel between your device and the VPN provider is secure and "private" from just about any third party you can think of - to include your Internet Service Provider (ISP).

Is a VPN right for you? It depends - users shouldn't rely on aggressive VPN marketing materials to determine this alone. However, while a VPN can benefit your privacy, it is important to understand how the "natural" limitations of a VPN also affect you. It is also important to put some thought into choosing a VPN provider.
