Your public Wi-Fi is not safe.
Hotel, airport, and coffee-shop Wi-Fi are still hunting grounds. Your phone's hotspot or a business VPN is a two-minute fix that shuts them down.
Hotel lobbies, airport lounges, coffee shops, conference centers — these networks still do real damage to real businesses. Not every day, not to every person, but enough that a serious business traveler should assume any free Wi-Fi is hostile and act accordingly.
What actually happens on sketchy Wi-Fi
Attackers set up access points with names like "Airport_Free_WiFi" or "Hotel-Guest" right next to the real ones. You connect, everything feels normal, and now every unencrypted bit of traffic flows through their laptop. Modern browsing is mostly encrypted, but email apps, old tools, and certain Wi-Fi login portals still expose enough to be useful — cookies, session tokens, credentials.
The fix isn't complicated. Use your phone's hotspot for work. Or keep a business VPN installed and turn it on the moment you're on a network you don't own. That single habit neutralizes the entire class of attack.
Two real scenarios
“A sales exec at a small manufacturer logged into the hotel's "Guest-WiFi-Login" page during a trade show.”
Red flag: It was a clone run from the next room. The login page asked for 'email verification' and collected their Microsoft 365 password.
“A consultant used an airport lounge Wi-Fi to send a client proposal with signed contracts attached.”
Red flag: Unencrypted SMB-style file transfer traffic was visible to anyone listening. Two weeks later, fake invoices went out to the same client.
Make it effortless
- Keep your phone's hotspot ready — most plans include it for free.
- Install a business-grade VPN on every laptop and phone. Configure it to auto-connect on unknown networks.
- If you must use public Wi-Fi, never log in, never access finance, never type a password.
- Turn off automatic connection to open networks on phones and laptops.
Set this up once, stop worrying.
A proper business VPN takes ten minutes per device to deploy. If you want us to roll it out across your team, just ask.
