Devices hold a wealth of sensitive info. A few one-time settings — encryption, updates, a strong screen lock — make a stolen device much less useful to a thief.
Encrypt and lock
FileVault (Mac), BitLocker (Windows), and on-by-default encryption on iOS/Android scramble your data so it's unreadable without your passcode.
- Set a strong passcode on every device.
- Turn on full-disk encryption.
- Enable Find My / Find My Device for remote wipe.
Stay patched & connect carefully
Software updates close known security holes. Public Wi-Fi can expose your traffic — a VPN gives you a safer tunnel.
- Enable automatic OS and app updates.
- Avoid sensitive tasks on open public Wi-Fi.
- Use a VPN on untrusted networks.
