VPNs are often presented as the miracle solution for online privacy. The reality is more nuanced. Here's what a VPN actually protects and what it doesn't.

What a VPN actually does

A VPN creates an encrypted tunnel between your device and a VPN server. This means your internet service provider (ISP) and others on the network can't see what you're doing online.

  • Public Wi-Fi: Protection against man-in-the-middle attacks on unsecured networks
  • Geolocation: Hides your real location by showing the VPN server's location
  • ISP monitoring: Your operator can't see your online activities

What a VPN does NOT do

⚠️ A VPN does not make you anonymous online. Websites can still identify you via cookies, browser fingerprinting, and your logged-in account.
  • It doesn't protect against viruses and malware
  • It doesn't hide your activity from the VPN provider itself
  • It doesn't secure your passwords or data if a site is hacked

When to use a VPN?

A VPN is particularly useful when: connecting on public Wi-Fi, accessing geo-restricted content, basic protection against ISP monitoring.

Which VPN to choose?

Avoid free VPNs: they typically fund their service by selling your data. Recommended options: Mullvad (most privacy-respecting), ProtonVPN (honest free version), NordVPN or ExpressVPN for everyday use.

💡 A VPN is just one tool among many. The combination of 2FA + strong passwords + regular updates is far more effective for daily security.
