Travel is when a private individual's digital life is most exposed — unfamiliar networks, devices that leave your hands, and an itinerary you didn't mean to publish. A short checklist, run before you go, removes most of the risk.
Before you leave
- Carry less. Travel with the accounts and data you'll actually need, not your whole digital life. A clean device beats a locked one.
- Update everything — phones, laptops, and the apps on them — the day before, not in an airport on hotel Wi-Fi.
- Turn off what reaches out on its own: auto-join Wi-Fi, device-to-device sharing, and any location sharing you don't need.
- Tell one trusted person the plan; tell the internet nothing in real time. Post the trip after you're home, not while you're away from it.
While you're there
Treat hotel and public Wi-Fi as hostile — use your own connection, a phone hotspot or a trusted VPN, for anything that matters. Don't plug into unknown USB ports. And assume any device you physically hand over — at a border, at a desk — is, for that moment, no longer entirely yours.
The most secure thing you can do before a trip is decide what not to bring.
None of this requires paranoia — just a routine. Run the same short list every time and it becomes muscle memory: the quiet competence that lets you stop thinking about it and enjoy being away.
