[HOT] : VPN: do you know what this tool is for and why it is really useful?

VPN, three letters that we see everywhere, but what is really behind it? A VPN can help you protect your privacy and browse the internet freely and anonymously.

In recent years, VPN services have multiplied, as have special offers on these services, and it is not necessarily easy to know exactly what a VPN is for. Most often, you may have had to use one to connect to your Intranet outside your company, by creating an encrypted connection, the famous virtual private tunnel which corresponds to the initials (Virtual Private Network). In the context of daily use, a VPN can nevertheless be useful for several scenarios. It can protect your anonymity and the privacy of your web visits. It can help you view content regardless of your geographic location. And above all, it can protect you when you browse on a poorly protected internet connection such as a public Wi-Fi network. All these advantages and more allow you to still enjoy a fast connection provided your VPN service has efficient servers, using the latest protocols. VPNs are available as a subscription, but they can also be integrated into a security suite.


A VPN for surfing the internet with complete peace of mind

The first use of a VPN, you may have already noticed when visiting the site of such a service, is to be able to hide essential information that allows you to identify you immediately, starting with two essential information: your IP address, and your geographic location. Not to mention the malicious uses that can be made of this information, it is data of great value to advertisers, booking sites and others who can use this information to serve targeted advertising, or modify the content according to your visits.

A VPN, as mentioned above, creates an encrypted connection between your computer, one of thousands of servers around the world, and the sites you visit. This connection generally corresponds to very advanced and robust AES 256-bit type encryption criteria. This therefore provides you with additional security when carrying out your online purchases, your transactions on banking sites, or even when filling out forms for administrative procedures.

This encrypted connection takes on its full meaning in the case of laptop use on a public Wi-Fi network, such as that of an airport, a cafe or a shopping center. You do not necessarily know the level of security of these networks, and some hackers can even create fake networks, whose name closely resembles that of an “official” hotspot, and on which they can engage in attacks such as “Man in the middle”, where your personal data is intercepted. In these cases, a VPN guarantees the privacy of your connection. Hackers will not be able to intercept your data. It can therefore be quite useful to adopt a VPN in order to protect your computer and your data, in addition to an antivirus and a firewall.

VPN: a tool to locate where you want

With a VPN, you can overcome a limitation that can taint your web experience: geolocation. Even if you have nothing to hide on your geographical location, some sites modify their content according to this geolocation, and this is particularly the case with video streaming services. Depending on the rights granted to TV channels depending on the country, or depending on constraints such as the chronology of the media, you may not necessarily be able to access certain “replays” of French channels from abroad, or not all the films available on such and such. such service in your country. With a VPN, you can choose your geolocation, and thus bypass these restrictions by connecting specifically to a server in a particular country, rather than automatically choosing the server closest to you. It actually depends on how you want to use the service.


But how does a VPN really work?

When you connect to the Internet, you establish a connection between your computer and the address you requested. This connection can be made in the clear, or by using various levels of encryption. A VPN service allows you to add an intermediary in this connection. Concretely, a VPN is a set of servers generally located around the world. When you connect to a VPN, you connect to one of these servers. This can be the closest server to your current location, set automatically by the client you have installed on your PC, Mac or smartphone. In a scenario where, for example, you want to remain anonymous without worrying about geographic content restrictions, this is what you will prefer, because this is the option that will cause you to lose the least bit of speed. It is the VPN server which will connect to the sites, via a virtual tunnel indecipherable from the outside. In fact, you could think of it as a big shielded cable, the contents of which would be invisible even to your Internet service provider. Because of this, you become really anonymous because you do not present your computer’s IP address, and if you choose your server in another country, your real geographic location is also hidden.
