There are 5 strong European-headquartered alternatives to Google Workspace for productivity and collaboration: Infomaniak kSuite (Switzerland), Nextcloud (Germany), Collabora Online (UK), Mailfence (Belgium) and Proton (Switzerland). All are headquartered in Europe with European majority ownership, process data exclusively on European infrastructure, and offer GDPR compliance by design.
Google Workspace processes European organisations’ emails, documents, calendar data, and file storage on Google’s US-subject infrastructure. Even with Google’s European data residency option, metadata and certain account data continue to flow through US systems subject to the CLOUD Act. For organisations handling sensitive communications and documents under GDPR, a European productivity suite removes this structural compliance dependency.

Why choose a European alternative to Google Workspace?
European productivity suites keep emails, documents, calendar data, and file storage in European jurisdiction — removing the structural exposure to the US CLOUD Act that affects Google Workspace regardless of European data residency settings. Several European alternatives offer end-to-end encryption that Google Workspace explicitly does not provide, addressing a significant security gap for regulated industries. For organisations subject to GDPR, NIS2, or internal data sovereignty policies, a European productivity suite removes one of the most pervasive compliance dependencies in the modern workplace.
