On hotel, café, and airport Wi‑Fi you often share a network with strangers. A VPN encrypts your connection to the VPN provider, so others on the same Wi‑Fi have a harder time seeing your traffic.
When can it make sense?
- Logging into banking, email, or work on public Wi‑Fi
- When you want to limit local network sniffing
- When you need a more stable tunnel on insecure networks
What a VPN does not solve
- Phishing, fake apps, or SMS scams
- Malware on your own device
- A service that requires a local IP (some streaming services)
- Logging into a fake “free Wi‑Fi” hotspot
What you should check with a provider
- No-logs policy and independent audits (if published)
- Kill switch, protocols (e.g. WireGuard), and simultaneous devices
- Server locations relevant to your route
- Price after the trial — avoid hidden renewals
