VPN (Virtual Private Network) routes your internet traffic through a remote server so that, to most sites, your connection appears to come from that server's location rather than your own. It's a privacy and security tool, not a magic shield.

What it does

  • Encrypts your traffic between your device and the VPN server, so a snooping network (like public café Wi-Fi) can't read it.
  • Hides your real IP address — sites see the VPN server's address instead.
  • Can bypass location blocks for some services (though many ban VPNs).

When it's worth it

  • On public Wi-Fi (cafés, airports) — a VPN protects you from the network itself.
  • When you want a more private connection on a trusted network.

What it's not

  • Not anonymity — your ISP still knows you're using a VPN, and the VPN provider can see your traffic.
  • Not a substitute for good passwords and 2FA.
  • It can slow your connection because traffic takes an extra hop.
A reputable VPN is a sensible extra layer, especially on public Wi-Fi. Pair it with strong passwords and 2FA — no single tool protects you on its own.
