Usage of VPN in The Real World - Tech-inmotion/VPNTechguy GitHub Wiki

If you catch yourself wondering what a VPN connection is, you are not alone. VPN services are quickly becoming a mandatory part of online life, yet many people do not fully understand what a VPN is and what exactly a VPN does. No matter where in the world you happen to be, the U.S., Germany, or anywhere else, the answers are always the same – albeit in different languages.

Put simply, it is an encrypted connection to a network of remote servers that allows users to access the internet in anonymity. A VPN acts as a middleman between the requester and the requester.

to get into a bit more detail about what VPN actually is, the concept has to be broken down a bit more than what we previously did. A VPN, or Virtual Private Network, as a service that is provided through private companies. 

These companies provide servers through which users can send and receive requests over the Internet. Acting as middlemen, VPN services take user requests on an encrypted channel, see the requests through, and then send them back to the user in an encrypted package. What that means is that when a person uses a VPN service, all of their Internet traffic is scrambled as soon as it leaves their personal device.

There are, of course, a few things to keep in mind when comparing VPN services as they are not all the same. Some VPN companies are purely for profit and offer some of the best services in the industry, while others provide a free service along with limited access and speeds. 

Also, some VPN services are better at different types of Internet traffic such as with getting past China’s great firewall and accessing streaming sites like Netflix. As a general rule, only the premium services will suffice for higher level use case scenarios and going with a cheap or free version of the VPN will likely and you end up with a service that has cut corners that should not have been cut.
