VPN adverts make bold claims about privacy, security, and invisibility online. The reality is more nuanced — a VPN is useful in specific situations, but it's not the blanket security solution that marketing often implies.

What a VPN Actually Does

A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. This does two things:

  • Hides your traffic from your internet service provider (ISP) — they can see you connected to a VPN but not what you're doing.
  • Masks your IP address — websites you visit see the VPN server's IP address, not yours.

That's it. A VPN does not make you anonymous, does not protect you from viruses, and does not prevent phishing. It's one specific tool for one specific job.

When a VPN Is Genuinely Useful

  • Public Wi-Fi — coffee shops, airports, hotels. On an unknown network, a VPN prevents others on the same network from intercepting your traffic.
  • Privacy from your ISP — if you don't want your internet provider to see which sites you visit, a VPN helps with this.
  • Accessing content in another country — if you need to reach a service that's geographically restricted.
  • Working remotely — many employers require a VPN to connect securely to company systems.

When a VPN Doesn't Help Much

  • Protecting against viruses or malware — use Windows Security for that.
  • Preventing phishing — being aware of suspicious emails and links is what works here.
  • Making you "completely anonymous" — websites can still identify you in many ways even through a VPN.
  • Securing your accounts — use strong passwords and 2FA for that.

Free VPNs: Be Careful

Free VPN services have to pay for their servers somehow. Many do this by logging and selling your browsing data — the exact opposite of what you're trying to achieve. If you decide to use a VPN, look for one with a clear, independently audited no-logs policy. Well-regarded paid options include Mullvad and ProtonVPN (ProtonVPN also offers a free tier with no data logging).

A VPN is not essential for most home users. If you're on a trusted home network, keep Windows and your browser updated, use Windows Security, and practise safe browsing — you're already doing the most important things. A VPN is a useful extra, not a foundation.
