What Is VPN And How It Works?

The initials VPN are for the term virtual private network. The objective and simple concept of a virtual private network is that it provides users with the ability to access a private network from an uninsured remote point outside that network, without compromising the security of the private network itself.  

Indeed, a VPN creates a tunnel through unsafe networks, which customers can use to access their private network without interference from other unsafe networks.   

As VPNs, therefore, they have to transmit private information through unsafe networks, such as the World Wide Web, they need to make sure that the data exchanged through these networks are kept secure by using a combination of Encrypted in data packets and authentication to allow access only to users with permission.  

How a Virtual Private Network works

It is the most common question that how a VPN works? A VPN works by encrypting your Internet connection so that your communications, data, locations and other information remain private when you are online. A VPN service can change your personal IP address by the IP address of a remote VPN server, which creates a level of privacy that you could not reach on a public server.   

When you use VPN (Virtual Private Network) technology, all network traffic, from voice to text to video, goes through a secure path between the client computer and the VPN server. Often called “tunnel,” this passage encrypts any information sent by the connection.  

The purpose of a VPN is to recreate a completely secure connection so that neither your ISP nor the sites you visit can identify you (from your IP address). You do not connect to the Internet using your own IP address, but the one that provided you with your VPN.  

The only information they will have access to is actually where your VPN provider is (which can be located thousands of miles away from your computer). This is why users are advised to consult the list of countries in which your provider has VPN servers.  

In this sense, it is necessary to distinguish the technology of the provider, which puts at your disposal these private virtual networks, at the right (for the best) of nearly 1500 access points distributed in a hundred countries, as well in Europe, then in the United States, Africa or Asia.  

By giving you a new IP address (often unique to each VPN user, sometimes even “disposable”) and by encrypting your personal data (which is particularly interesting if you connect via an open network), a VPN makes it almost impossible to do anything. the third party to intercept your activity on the net.

Advantages of VPNs

Among the many advantages that can offer a VPN, the following are the most remarkable:  

1. It works for all kinds of applications. This is because it is capable of routing all Internet traffic.  

2. Easy connection and disconnection. Once you have configured it, you can activate and deactivate the connection whenever you want.  

3. They provide an extra security. Above all, for WIFI access points they are highly recommended.  

4. You can falsify your location. This is used to avoid censorship or access content limited to a certain region that you would not otherwise have access to.  


A virtual private network is a network that runs on a public network. It is the extension of a private network that incorporates links through public networks.   

It allows you to communicate between computers through a public network in a way that uses a private connection. Companies or organizations are adopting VPNs to ensure Internet security.
