Pre-trip device hardening, loaner phones, secure travel routers, and a country-specific risk briefing before the principal departs.
International travel is the riskiest thing many of our principals do digitally. Border inspection, hostile networks, opportunistic theft, and surveillance vendors are all real. We prepare devices, networks, and procedures specifically for the trip in question.
If a calendar shows where the principal will sleep on Friday, that calendar is sensitive. We treat it that way.
NDA on first call. Typical reply within one business day.
