Microsoft Office, now sold as Microsoft 365, remains the standard for documents, spreadsheets and email in most organisations. It is subscription-based for both households and businesses, with free web-only versions of Word and Excel. Microsoft is based in Redmond, Washington, and US legislation applies to data held in its cloud wherever the servers are.

Why choose Nextcloud over Microsoft Office?
The decisive argument is data jurisdiction. Microsoft Office is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Nextcloud removes that overhead. As a Germany-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
