Bottom line: A US court ruling weakens the legal basis of the EU-US Data Privacy Framework, making the evaluation of European alternatives to Microsoft services more urgent for IT departments.
A US court ruling has undermined a foundational pillar of the EU-US data protection agreement. For IT departments in Europe, the question of migrating to European alternatives to Microsoft services is now taking on new urgency.
A recent ruling by a US court has consequences for the EU-US Data Privacy Framework, which was intended to provide legal certainty for transatlantic data exchange between European companies and US providers such as Microsoft. As a result of the decision, the agreement loses one of its foundational legal bases. This brings the long-debated issue of digital sovereignty for European IT infrastructures back into focus, particularly for organizations that rely heavily on Microsoft products such as Microsoft 365, Azure, or Teams.
For CTOs, this legal uncertainty means that the previous assumption—that personal data could be reliably transferred to or processed in the USA under the Data Privacy Framework with legal certainty—is no longer fully valid. Those renewing or newly signing cloud contracts with US hyperscalers today must reassess the legal situation and, where necessary, examine alternative safeguard mechanisms such as standard contractual clauses or relocating data processing to European data centers. Migrating away from Microsoft services is technically and organizationally demanding, which is why planning certainty for 2026 is in high demand.
The report assesses which European alternatives to Microsoft products are functionally viable today and where gaps still remain, for instance in feature scope, depth of integration, or the maturity of the ecosystems. For IT decision-makers, this provides a basis for determining which workloads can be migrated in the short term and where a complete transition away from Microsoft services will not realistically be achievable in the coming year.
