Microsoft Teams
USMicrosoft Teams is a business communication and collaboration platform combining chat, video meetings, file storage, and application integration within the Microsoft 365 ecosystem.
The Case for Wire
- Wire stores all data exclusively in Germany, EU, under European jurisdiction. Unlike Microsoft Teams, which is subject to the US CLOUD Act and FISA Section 702, Wire cannot be compelled by foreign governments to hand over your data.
- Wire offers a Data Processing Agreement (DPA) that is fully aligned with GDPR Article 28. There is no legal ambiguity about data transfers or adequacy decisions — your data processor is European, and the law that governs it is European.
- As an open-source solution, Wire gives you full code transparency. You can verify that the software does what it claims, audit it for security vulnerabilities, and even self-host it for maximum control — something that is simply not possible with Microsoft Teams.
- You can try Wire for free before committing. This makes it easy to evaluate whether it meets your needs alongside — or as a replacement for — Microsoft Teams, without any financial risk.

Wire vs Microsoft Teams — FAQ
Is Microsoft Teams GDPR compliant?
Microsoft Teams may offer GDPR compliance features and EU data residency options, but as a US-headquartered company, it remains subject to the US CLOUD Act and FISA Section 702. These laws can compel US companies to hand over data regardless of where it is stored. The EU-US Data Privacy Framework provides some safeguards, but its predecessors (Safe Harbor and Privacy Shield) were both invalidated by the European Court of Justice. Wire, as a European company, is not subject to these US laws at all.
How does Wire compare to Microsoft Teams in features?
Wire offers End-to-end encrypted messaging, Encrypted voice and video calls, Group video conferencing, File and screen sharing, and 5 more features. While Microsoft Teams's ecosystem may be larger due to its market position, Wire covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Microsoft Teams) and data sovereignty with regulatory certainty (Wire).
Can I migrate from Microsoft Teams to Wire?
Yes. Most European software providers, including Wire, offer migration tools or documentation to help you transition from US-based services. Under GDPR Article 20, you have the right to data portability — meaning Microsoft Teams must provide your data in a machine-readable format. The migration process varies in complexity depending on your data volume and integrations, but for most teams it can be completed within a few days to a few weeks.
