Un VPN en vaut-il la peine ? Une panne honnête
24 juin 2026 · 3 min de lecture · Commentaires
Les publicités VPN sont partout : sur YouTube, les podcasts, tous les sites technologiques. La plupart d’entre eux exagèrent ce que fait réellement un VPN. Voici un aperçu honnête des moments où un VPN est réellement utile et de ceux où il ne l'est pas.
Ce que fait réellement un VPN
- A VPN (Virtual Private Network) routes your internet traffic through a server run by the VPN company, then out to the internet. This has two effects:
- Websites you visit see the VPN server's IP address, not yours. So your location and identity are hidden from those sites.
- Your internet provider (ISP) can see you're connected to a VPN, but cannot see which sites you're visiting.

Quand un VPN aide vraiment
- Public Wi-Fi. Coffee shops, airports, and hotels run open networks where other users can sometimes intercept unencrypted traffic. A VPN prevents this. This is the single most compelling everyday use case.
- Stopping your ISP from selling your browsing data. ISPs in many countries are legally allowed to log and sell your browsing history. A VPN stops this, though you're now trusting the VPN company instead.
- Accessing geo-restricted content. Netflix libraries, BBC iPlayer, sports streams. A VPN lets you appear to be in a different country.
Quand un VPN n'aide PAS
- Hiding from Google or Facebook. You're logged into these services. They know exactly who you are regardless of your IP address. A VPN does nothing here.
- Complete anonymity. You can still be tracked via browser fingerprinting, cookies, and account logins. A VPN masks your IP — that's all.
- Security on its own. A VPN doesn't protect you from phishing, malware, or weak passwords. It's not a replacement for good security habits.

Quel VPN utiliser
- Mullvad — the most privacy-focused option. Accepts cash payment, requires no email to sign up, has a strict no-logs policy that has been independently audited. €5/month.
- ProtonVPN — based in Switzerland (strong privacy laws), open-source, audited, has a free tier. Excellent choice for most people.
- Avoid free VPNs unless they're from a trusted provider like Proton. Free VPN companies often make money by logging and selling your data — the exact opposite of why you'd use a VPN.
Si vous utilisez régulièrement le Wi-Fi public, un VPN vaut entre 5 et 10 $/mois. Si vous naviguez principalement depuis chez vous sur un réseau de confiance, l'avantage est moindre, mais la protection contre le suivi du FAI à elle seule est une raison suffisante pour de nombreuses personnes.
