Free public Wi-Fi at your local coffee shop, airport, or hotel is incredibly convenient when you need to get some work done on the go. However, because these open networks lack encryption, they leave your data vulnerable to anyone else connected to that same access point.
When you connect to a public hotspot, your device isn't just talking to the router, it is broadcasting its traffic into the open air. In a busy public space, a bad actor on the same network can use basic, free software to scan and intercept unencrypted data passing through the router.
To keep your personal information secure when you're working away from your home MINET connection, make a few simple adjustments to your routine:
Save sensitive tasks for later. If you need to check your bank accounts, make a purchase, or log into highly sensitive portals, wait until you're back on a secure network. If you absolutely have to do it now, rely on your phone's cellular data rather than the shop's free Wi-Fi.
Use a Virtual Private Network (VPN). A VPN creates an encrypted tunnel for your internet traffic. Even if someone intercepts your data on an open network, all they will see is scrambled, unreadable code. Use a reputable VPN service and turn it on before you start browsing.
Turn off auto-connect. Set your phone, tablet, and laptop to "ask to join" networks instead of connecting automatically. This prevents your device from quietly joining unsecured or spoofed networks without your knowledge.
Use your mobile hotspot. If you have a decent cellular signal, tethering your laptop to your phone's mobile hotspot is far more secure than using public Wi-Fi. It keeps your connection private and off the shared public router.
Public Wi-Fi is great for reading the news or checking a map, but it is not the place for your private accounts. Taking a few seconds to switch to a hotspot or turn on a VPN keeps your data where it belongs, private.
