When a team picks a new tool, the questions are familiar: which features, how much per user, how it fits the existing stack. A question gets asked far less often: where does our data physically live, who can access it, and could we take it with us tomorrow if we wanted to leave? As data becomes an organization's most valuable asset, that is no longer a detail you can defer.
What data sovereignty actually means
Data sovereignty is often confused with encryption. Encryption is necessary but not sufficient; sovereignty is broader and has three dimensions. First, location: which country and legal jurisdiction your data sits in. Second, control: who can actually access your data — including the vendor, its sub-processors, and AI models. Third, portability: whether you can genuinely export the data in an open format and move it elsewhere.
Sovereignty is not about hiding your data. It is about being the one who decides where it lives, who can read it, and whether you can leave.
Why it's becoming table stakes
Several trends converged at once. Regulation tightened: GDPR and the court rulings that followed sharply limit the conditions under which personal data can cross borders. AI changed the picture: your chats, documents, and customer data can flow into model training unless you explicitly opt out. Cloud concentration created a dependency risk; infrastructure pooled into a few large providers brings geopolitical and commercial fragility. Finally, buyers now ask: in enterprise procurement, 'where is our data and who can see it' is a standard security-review item.
The quiet sovereignty cost of a typical stack
A team running on fifteen separate SaaS tools is — without realizing it — spread across fifteen jurisdictions, fifteen sub-processor lists, and fifteen retention policies. When chat lives in one place, tasks in another, and documents on a third platform, honestly answering 'where is our data and who can access it' becomes nearly impossible. Export usually ends in context-free CSV graveyards; data that is portable in theory moves nowhere in practice.
What real ownership looks like
The good news is that sovereignty is not all-or-nothing; there are concrete questions you can ask. When evaluating a tool, the items below surface real control, beyond marketing promises:
- Data residency you choose: Can you decide which region (e.g., the EU) holds your data, or is it decided for you?
- A self-host option: Can you run the platform on your own infrastructure or as a single-tenant deployment when needed?
- Clear sub-processor boundaries: Which third parties touch your data, and is that list transparent?
- No training by default: Your content should not be used to train AI models without your explicit consent.
- Open, complete export: Can you take all of your data with you in a context-preserving, genuinely usable format?
How we think about it at Polybase
We built Polybase around the principle of 'your data, your rules.' Workspaces are hosted in the EU by default; for teams that need it, we offer flexible deployment options, including running the platform on your own infrastructure. Because chat, tasks, documents, and calls come together in a single workspace, there is not fifteen separate data boundaries to govern but one — turning sovereignty from an abstract promise into an auditable reality.
Decide where your work lives.
Bring your team together in a single workspace that is hosted in the EU, exportable, and able to run on your own infrastructure when you need it.
