A VPN or virtual private network is a tunneled session established between your computer (or local network) and a remote server, or entire remote network. The tunnel travels through the inter-connected web of networks we call the Internet. A VPN tunnel on-line is to the Internet as a physical tunnel blasted through rock is to a mountain highway. They both provide secure transportation to the other side.
When your car passes into and through the mountain highway tunnel, it becomes hidden from any observer that is not in the tunnel with you. The same goes for the information exchanged between your computer and the remote systems it communicates with over a VPN. Data in the tunnel is hidden from other nodes on the Internet by the encryption algorithm (math scramble) that established it.
Microsoft offers a free VPN connection to their platform from their Edge web browser. This essentially means that only you, Microsoft, and the web farm you are using will be able to see what you are doing. The catch is that the system is only free for 5 GB of information per month.
To be limited, free, and still try to be useful, there are several compromises Microsoft has made. The Edge VPN offering is constrained to just browser traffic. A traditional VPN service would cover all data types. Not all browser traffic is sent through the tunnel either. This protects only certain sites and excludes things like video streams in the browser.

To enable this feature first update Edge to the newest version. Then click the Browser Essentials button in the tool bar. It is the heart shaped icon. Scroll down to the VPN section and click the toggle.
