Les réseaux privés virtuels enfin démystifiés

Les VPN sont de plus en plus importants : à quoi servent-ils et comment peuvent-ils vous être utiles ? 

Les FAI. L’adresse IP. Le géoblocage. Vous en avez peut-être déjà entendu parler en lisant des informations à propos des VPN (réseaux privés virtuels). Cette brève introduction sur les VPN vous aide à tout comprendre et vous explique en quoi ils peuvent vous simplifier la vie.

What is a VPN?

A virtual private network, or VPN, creates a private network across a public internet connection by masking the user’s internet protocol address (IP). The private network is established through a tunneling protocol that involves encrypting traffic data. Basically, a data tunnel that connects your local network to an exit point in a completely different location makes it seem that you are accessing the internet from another place – it could be a different city or even country on another continent. The data is encrypted, preventing internet providers and potential eavesdroppers from decoding the data. By combining tunneling protocols and encryption, VPN connections are highly secure and private.

How does a VPN work?

Data is uploaded from your device to the VPN server and exits the public internet connection. Other users and services cannot trace you as your device seems to have the IP address of the VPN server. Because of this, even your Internet Service Provider (ISP) cannot monitor your online activities, and your privacy is secured.

Why should you use a VPN?

Using a VPN has several advantages for different use cases, from online shopping to gaming and streaming. VPNs empower people from all walks of life: movie lovers, globetrotters, gamers, and security-aware users. Here are just a few of the benefits of using a virtual private connection for anonymous browsing.


Safely surf on public Wi-Fi 

Phantom VPN creates an encrypted tunnel between your device and a remote VPN server operated by Avira. After client and server have verified each other as authentic, all incoming and outgoing traffic is routed through that tunnel and your data is encrypted.

Secure your online transactions 

Online banking is very convenient, especially on the go, but it is one of the preferred targets of cybercriminals. To protect your financial data, use a VPN for your online banking activities, especially when using public Wi-Fi. A VPN is also useful when shopping online. In addition to your credit card details, you also provide personal information such as your address and phone number. Imagine how much information cybercriminals can collect if they track your data. The encryption provided by a VPN connection adds another layer of protection and provides more safety when shopping online. 

Browse anonymously 

While browsing, you leave traces and companies track your activities for targeted advertising or to collect and sell information about you. Establish a free VPN connection to browse anonymously online, protect your privacy, and prevent advertisers from targeting you. The IP address of your device is hidden, and others cannot monitor your activities.

Bypass geo-blocking and firewalls 

By hiding your real IP address, you can bypass regional censorship and geo-blocking. Many websites and services are blocked in certain regions, preventing users from accessing them. You might have encountered messages like “This content is not unavailable in your country” when browsing YouTube. With a VPN, this is not a problem: you can appear to access the service from a whitelisted location and get access to geo-restricted content. For example, you can choose a VPN server in the UK to watch a British TV show you like and bypass geo-blocking. This feature also enables gamers to beat restricted gaming servers and play against competitors around the world. With a VPN, you can: 

  • Listen to music without restrictions
  • Watch TV shows and films from anywhere
  • Access censored social media networks
  • Check for better deals like cheaper air tickets

Keep your home office secure 

VPNs are crucial to keeping confidential data secure while working from home. In fact, this is the motivation behind developing VPN technology. In 1996, Gurdeep Singh-Pall, a Microsoft employee, laid the basis of VPN technology by creating the Point-to-Point Tunneling Protocol (PPTP) to enable people to work securely and effectively from the privacy of their homes. Remote working is risky: attackers can intercept data from unencrypted connections. Using a secure VPN connection with advanced encryption to connect to your company’s network, you can ensure the sensitive data you send and receive is protected.
