The Case for Collabora Online

- Collabora Online 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, Collabora Online 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 365.
- You can try Collabora Online for free before committing. This makes it easy to evaluate whether it meets your needs alongside — or as a replacement for — Microsoft 365, without any financial risk.

Collabora Online vs Microsoft 365 — FAQ
Is Microsoft 365 GDPR compliant?
Microsoft 365 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. Collabora Online, as a European company, is not subject to these US laws at all.
How does Collabora Online compare to Microsoft 365 in features?
Collabora Online offers Document editing, Spreadsheets, Presentations, Nextcloud integration, and 5 more features. While Microsoft 365's ecosystem may be larger due to its market position, Collabora Online covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Microsoft 365) and data sovereignty with regulatory certainty (Collabora Online).
Can I migrate from Microsoft 365 to Collabora Online?
Yes. Most European software providers, including Collabora Online, 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 365 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.
