What is a VPN?

It can be compared to a car entering a tunnel to hide from a chase.

The VPN is the tunnel that connects the many roads. No one from the outside knows where the cars entering it will end up. No one from the outside knows what happens in the tunnel.

You’ve probably heard about VPNs more than once. 

VPNs are often recommended because you can use the network to access geographically blocked content and generally increase security when using the Internet. The truth is, however, that accessing the Internet through a VPN can be just as dangerous as going direct.


How does VPN work?

Chances are you have a Wi-Fi router at home. The devices connected to it can exchange data even without the Internet. So you have your own private network, but you need to be physically within range of the router’s signal to connect to it.

A VPN (Virtual Private Network) is a virtual private network. It runs on top of the Internet, so you can connect to it from anywhere.

For example, the company you work for can use a Virtual Private Network for remote employees. With a VPN, they connect to the work network. In doing so, their computers, smartphones, or tablets are virtually transported into the office and connected to the network from inside. To log into the virtual private network, you need to know the address of the VPN server, a username, and a password.

Using a VPN is pretty easy. Usually, the company raises a VPN server somewhere on a local computer, server, or data center and connects to it using a VPN client on the user’s device.

All current operating systems now have built-in VPN clients, including Android, iOS, Windows, macOS, and Linux.

The VPN connection between the client and the server is usually encrypted.


So, is a VPN a good thing?

 Yes, if you are a business owner and want to secure corporate data and services. By allowing employees into the work environment only through a VPN and accounts, you will always know who did and what they do.

Moreover, the VPN owner can monitor and control all traffic between the server and the user.


Is it possible to use a VPN outside of work? 

Yes. The most common type of VPN service is free public services. You’ll find thousands of these goodies on Google Play, the App Store, and the Internet. They provide VPNs for free and take care of all the associated costs, including data center fees, development of convenient applications, support, and so on. All they need in return is information about everything you do online to sell your detailed digital portrait to advertisers. At the same time, they can show you their own ads based on your interests. It’s simple and honest.

Paid VPN services are a different matter. Theoretically, they live off subscription fees and don’t use user data for sales and advertising. The problem is that it is very difficult to check their honesty.
