Public WiFi at hotels, airports, and coffee shops is one of the biggest everyday security risks. Here is exactly how to protect yourself completely.
Why public WiFi is dangerous
Most public networks do not encrypt traffic between your device and the router. Anyone on the same network can capture your data using freely available tools. Evil twin attacks create fake hotspots with names identical to legitimate ones. Man-in-the-middle attacks position an attacker between you and the router to read and modify traffic.
Six rules of public WiFi safety
Always connect through a VPN before doing anything else. Verify the network name with staff before joining. Avoid banking or email on public WiFi without a VPN. Use only HTTPS sites and never proceed past certificate warnings. Disable auto-connect to open networks in your device settings. Enable your device's built-in firewall.
How a VPN completely solves the problem
When connected to a VPN on public WiFi, all your traffic is encrypted before it leaves your device. An attacker capturing the entire network's traffic collects only encrypted data they cannot read. Man-in-the-middle attacks and packet sniffing become completely ineffective.
Auto-connect on untrusted networks
NordVPN can be configured to connect automatically whenever it detects an unsecured WiFi network — protecting you even if you forget to enable it manually.
