Claude Cowork: sovereignty score and 8 European alternatives

Claude Cowork is Anthropic's agentic mode for knowledge work beyond coding, such as research, analysis and producing documents, decks and spreadsheets. A user states a goal, and Claude works through the steps across the folders and connected tools the user selects, such as local files, Slack and Google Drive, then returns finished work for review. It shows each step, asks approval before significant actions and can run scheduled tasks. The desktop app is the main experience.

Anthropic is a US company. Cowork can run with a Claude account or with the organisation's own cloud provider: Amazon Bedrock, Google Cloud or Microsoft Foundry. Team and Enterprise administrators can set access per team and stream activity to a SIEM through OpenTelemetry. With Anthropic's own API, the inference geography can be set to global or US only, so organisations needing a specific region should check which route they use.

Why digital sovereignty matters with Claude Cowork

Claude Cowork is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Claude Cowork hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Claude Cowork is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Claude Cowork together with your other vendors and gives a total score, a heatmap and the main risk drivers.
