Don't travel with data on your systems. Don't travel with automatic access to other systems. Put data on a private cloud and remotely access it, as needed, through a VPN. Don't trust DNS, use IPs for direct VPN access.

Use 2FA and if truly paranoid, don't bring the HW device with you or know the passphrase yourself without calling another person when traveling. You want to be able to tell border officials that you honestly do not know the passphrase.

Should go without saying, but whole disk encryption is required for all portable devices ... and beware of known bugs (there's an encryption bypass for certain versions of Win10 today) around whole disk encryption. Look up 'evil maid attack.'

Smartphones need full encryption, VPNs and 2FA as well, especially when crossing borders.
