How we operate
European policymakers now openly discuss America's tech kill switch — the ability to cut a person, a company or a nation off from the digital infrastructure modern business depends on. It has already happened.
In 2025 the US sanctioned ICC prosecutor Karim Khan. Microsoft cut off his email, banks and card networks froze him out, and the Court itself moved to Proton Mail and the openDesk suite — disconnection in days, not years.
EU governments are launching sovereignty programmes — the Digital Euro, Gaia-X, European payment rails — because depending on a handful of foreign giants is a single point of failure.

European sovereign-cloud spending is forecast to grow 83% this year — from $6.9bn to $12.6bn — overtaking North America by 2027.
Diagnose your exposure, fix it with the right help, and prove you have it under control. Use one piece or all four.
Vendors get acquired. Workloads drift across regions. A provider you trusted last year changes ownership or jurisdiction. New regulations keep landing. Sovereignty Posture Management watches it all continuously — and tells you the moment your exposure, or the law, changes.
