What is a VPN and when should you use one?
A VPN encrypts your internet traffic so no one on the same WiFi network can see what you're doing. You should use one when you're on public WiFi at a café, airport, or hotel — it stops people from stealing your passwords or banking details. For home WiFi and cellular networks, you don't need one.
A VPN (Virtual Private Network) creates an encrypted tunnel for your internet traffic. Instead of your data going straight to websites where it can be seen by others on the same WiFi network, the VPN scrambles it first. It's like sending your mail in a locked box instead of a postcard — the postal worker can't read what's inside. VPNs are helpful on public WiFi, but they're not a magic shield and they won't protect you from viruses or bad decisions.

Common mistakes to avoid
- Thinking a VPN protects you from viruses or malware — it doesn't, a good antivirus does
- Assuming you need a paid VPN when free options (like the ones built into some devices) work just as well
- Using a VPN on home WiFi thinking it adds security — your home WiFi is already secure if it has a password
Signs you need professional help
- You're still unsure whether you need a VPN after reading this
- You want recommendations on which VPN to use
