Most organizations can't just flip the switch on Microsoft 365. However, they need to shield sensitive communications from the reach of the US CLOUD Act and—per NIS-2 mandates—require an emergency communication system that is completely independent of their primary IT stack. The traditional industry answer has been a binary choice: stay or migrate. We’re introducing a third way.

Instead of ripping and replacing M365, a sovereign communication layer runs continuously in parallel. Standard business data stays in O365, while highly sensitive conversations are fully end-to-end encrypted via high-secure MLS. The game-changer is a multi-protocol client that unifies Teams, WhatsApp, Matrix, and MLS into a single, intuitive interface. In the event of an outage, all relevant data is already mirrored within the EU. Users can simply keep messaging in the exact same client—the system seamlessly handles the protocol switch behind the scenes. No "Plan B" to deploy, no new tools to learn. And if you ever decide to leave M365 entirely? The foundation is already built, but the choice is entirely yours.
Using an anonymized Critical Infrastructure (CI) use case from the DACH region, we will dive deep into: the continuous mirroring of identities, chats, emails, and files; failover capabilities between on-premise setups and an EU-sovereign cloud; MLS encryption; audit-proof logging; and native integration with ID Austria/SSO.
