If you work on a computer or mobile device away from home, you probably use Wi-Fi hotspots in hotels, cafes, restaurants, airports, or on campus. The problem is, there is no way to know exactly how secure those networks are.
The best ways to stay safe on a public Wi-Fi network is to use a Virtual Private Network (VPN). A VPN is basically an encrypted tunnel between your device and the Internet that makes all your online interactions safe from prying eyes lurking on the same network.
