Data Residency & Sovereignty
Win the Deals That Require Data Sovereignty
A sovereignty mandate is not a region setting, it is a legal question about who can compel your customer’s data. When a European enterprise or public-sector customer requires their data to stay under their own jurisdiction, Tensor9 runs your existing product inside their sovereign cloud, VPC, or data center, without a rewrite. Your keys, their jurisdiction. Our control plane is never in the path of the data.
A Sovereignty Mandate Is a Hard Constraint, Not a Checkbox
Most compliance asks have a configuration answer. Sovereignty does not. It is a legal question about which government can compel the data, and a deployment in a US-operated account does not qualify, no matter which region it runs in.
The CLOUD Act Reaches Your Region
Under the US CLOUD Act, a US-headquartered company can be compelled to produce data it controls, wherever the servers sit. AWS in Paris moves the data onto local soil but leaves a US company operating it, so it stays reachable.
A Region Setting Isn’t Sovereignty
SOC 2, encryption at rest, and a region in your customer’s country satisfy the soft version. A sovereignty mandate is about jurisdiction over the operator, and no config option changes who holds legal authority.
No Sovereign Option, No Seat at the Table
Regulated and public-sector customers in Europe apply the same rule to what they buy as to what they run. If your product touches that class of data and runs in a US account, it is not a candidate at all.
Managed Services Don’t Exist There
Your product leans on S3, RDS, DynamoDB, and SQS. A sovereign provider or a customer’s data center has no AWS-branded counterpart, so meeting the mandate the usual way means re-architecting the stack.
Deploy Into the Customer’s Sovereign Environment, Without the Rewrite
Sovereignty reduces to the self-hosting problem: your product running on infrastructure your customer controls, in a jurisdiction they trust, with the data staying inside. Tensor9 gets you there from the stack you already have.
Run in the Customer’s Jurisdiction
Deploy into a sovereign provider like Scaleway or OVHcloud, a private VPC in your customer’s account, an on-prem cluster, or an air-gapped facility. The data stays under your customer’s law, operated by your customer, not by a US account.
Translate Your Managed Services
Your containers run on your customer’s Kubernetes the way they run on EKS. Tensor9 translates the managed services around them: Postgres, Redis, Kafka, and S3-compatible object storage, repointed to equivalents running in the cluster.
Proprietary Services, Covered
For AWS-only services like DynamoDB and SQS, Tensor9 targets an open-source API drop-in such as ScyllaDB’s Alternator or ElasticMQ for the API surface your application uses, so your code keeps its AWS SDK calls unchanged, or routes them through the compatibility layer.
One Codebase, Every Jurisdiction
Each sovereign target is generated from the same description of your stack, so adding a jurisdiction is a new build target, not a separate per-country fork to maintain.
Data Never Leaves the Jurisdiction
Your application runs entirely inside the sovereign environment, and the sensitive data never leaves it. Tensor9’s control plane receives only operational metadata, never your customer data itself.
How Tensor9 Works
Bind, Translate, Deploy
Bind the stack you already have, the Terraform that describes your AWS product, without modifying it. Tensor9 translates it for your customer’s sovereign target, mapping managed services to equivalents that run in their Kubernetes and adding a compatibility layer where a service is AWS-only. Deploy into their sovereign cloud, VPC, or data center. A controller stays resident to keep the deployment on your latest release and stream operational telemetry back to your tools.
Frequently Asked Questions
Tensor9 lets software vendors run their existing product inside a customer's own environment and jurisdiction, without a rewrite. We translate your stack for each sovereign target from one codebase, so a data-residency mandate becomes a deployment target instead of a re-architecture.
- European enterprise and public-sector deals where your customer requires the data, and the software touching it, to stay under their own jurisdiction.
- GDPR, DORA, and EU AI Act obligations that a US-operated deployment cannot satisfy.
- Deals blocked because your product only runs in your own AWS account, not in your customer's sovereign environment.
Because sovereignty is about jurisdiction over the operator, not the physical location of the servers. Under the US CLOUD Act, a US-headquartered company can be compelled to produce data it controls wherever it sits, so the product has to run on infrastructure operated within your customer's own jurisdiction.
Sovereign providers like Scaleway and OVHcloud, a private VPC in your customer's own account, on-prem data centers, and air-gapped facilities, via Kubernetes. Anything with a wire-compatible equivalent runs today: Postgres, Redis, Kafka, and S3-compatible object storage.
Where an open-source API-compatible project exists, Tensor9 targets it in the cluster and your code keeps its AWS SDK calls unchanged, for example ScyllaDB's Alternator for DynamoDB or ElasticMQ for SQS. Where there is no drop-in, you adapt that part of the application or route it through the compatibility layer.
No. Tensor9 translates your existing cloud-native stack into equivalents that run in your customer's environment, so you deploy into their jurisdiction without maintaining a separate codebase per country.
On a sovereign deal, getting your live dataset into the jurisdiction and keeping it consistent through cutover is the critical path, and it is separate work you own. Tensor9 stands up the target infrastructure inside the sovereign environment; you plan and run the data move.
No. The control plane receives only operational metadata, never your customer's data, and it can run in-jurisdiction or be operated by your customer. The data stays under local control, so the jurisdiction question is answered where it matters.
