Your Data Is in Switzerland — But Is It Really Yours?
David Furrer
Data Governance Expert
Three questions. Answer them honestly.
- Who can access your company's data today and under which jurisdiction?
- Could you migrate off your current data platform within six months with all pipelines, models, and dashboards intact?
- Do you know the names, locations, and legal obligations of the people who operate your data stack?
Most data leaders answer yes instinctively. Then they think about it for thirty seconds and the certainty fades. Because "our data is in Switzerland" is not the same as "we control our data." And in 2026, that distinction matters more than ever.
The Sovereignty Illusion
Swiss companies running their data on Databricks, Snowflake, or Microsoft Fabric often believe they have made a solid, modern choice. And technically, they have. These are powerful, well-engineered platforms. But power and sovereignty are not the same thing.
The CLOUD Act problem. All three are US-headquartered companies. The CLOUD Act grants American authorities the right to demand access to data from US-based providers, regardless of where that data is physically stored. Your data centre is in Zurich, your compliance team has ticked every nLPD box, and yet a US court order can compel your provider to hand over your data without notifying you first.
Vendor lock-in. Over time, pipelines are built around proprietary formats, dashboards depend on native features, and teams develop platform-specific skills. The switching cost grows silently with every sprint until a migration is technically possible but practically unthinkable.
Operational opacity. When you contract with a hyperscaler, you gain a platform but lose visibility into who operates it. In regulated industries like banking or insurance, where FINMA explicitly requires oversight of data processing, this is not just uncomfortable. It is a compliance liability.
Data Governance: The Prerequisite
Better tooling alone does not solve sovereignty problems. Before any platform decision, organisations need to answer a more fundamental question: what do we actually know about our own data?
Without data classification, clear ownership, and enforced access policies, even the most sovereign platform becomes a black box from the inside. Governance defines which data can move where, who is responsible for what, and which regulatory requirements apply to which datasets. It does not replace a sovereign platform, it makes one possible.
A well-designed governance framework directly answers the three questions at the start of this article.
Open Data Stack: Built Differently
This is the gap that Open Data Stack — developed by ti&m — is designed to close. The difference from Snowflake, Databricks, or Microsoft Fabric is philosophical before it is technical: sovereignty is not a feature to be purchased. It is a design principle.
| Challenge | Snowflake, Databricks, MS Fabric | Open Data Stack |
|---|---|---|
| Legal jurisdiction | US CLOUD Act applies | Swiss company, Swiss law |
| Vendor lock-in | Proprietary formats and features | Based on open source, assets stay with you |
| Operational visibility | Global support teams, opaque access | Swiss-based team, named and accountable |
| Auditability | Partial lineage | Full lineage, source to dashboard |
| AI data control | Limited governance on LLM access | Integrated MCP server with granular controls |
| Deployment | Cloud only | On-premises, own cloud, or Swiss SaaS |
Conclusion
Organisations that cannot answer those three opening questions confidently have, often unknowingly, outsourced their digital sovereignty to vendors with different laws, different incentives, and different obligations.
The solution requires both dimensions: governance to know what needs protecting, and a platform built to protect it.
Sovereignty is not a feature you can add later. It is a foundation you either build or you don't.
