We hear about VPNs everywhere. Whether by videographers who promote these services or by high-tech sites that share the best promotions of the moment. But what exactly is a VPN?
What is the definition of a VPN?
VPN is the abbreviation for “Virtual Private Network”. It is a private network offering the user complete anonymity when browsing the internet. Each Internet user has an IP address which can then be identified and traced back to his real identity if necessary.
When using a VPN, your IP address then becomes invisible to all the web services you are trying to access. You thus become anonymous. All the information you want to access then circulates in an encrypted tunnel becomes indecipherable.
If it allows you to browse without anyone being able to track you down or trace you back, there are other benefits to using a VPN. In particular, did you know that when using a public WiFi network, it was possible that malicious people could retrieve information about you?
Indeed, on a network open to all, it becomes easy for someone wishing to harm you to “listen” to what passes on this connection. Some of your information can then be recovered. By using a VPN, you encrypt everything that passes from your machine to the web server, making this interception impossible. You can visit cubik to learn more about it.
Another possible interest: bypassing censorship in certain countries. In China in particular, the government blocks the sites of web giants such as Facebook and Google. They prefer their fellow citizens to use Chinese alternatives to these tools, making it easier for them to monitor them.
If you are traveling to China, theoretically impossible for you to use Google Maps. However, with a VPN, you can easily bypass this censorship and regain access to all your favorite services.
Finally, a VPN also makes it possible, for example, to bypass the geo-blocks of certain services. Did you know that the Netflix catalog is different in each country in particular? In the United States, Americans can thus enjoy recent films where in France it will often be necessary to wait more than 36 months to enjoy them.
By connecting to a VPN and choosing a server located in the United States, Netflix will then believe that you are connecting from that territory. It is therefore the American catalog to which you will now have access… Nothing could be simpler!
