SOVEREIGN AI

From Scattered Data
to Sovereign AI

Your most valuable knowledge already exists in your systems and documents. sDEN helps institutions and enterprises unify it and run AI on it inside an environment they control.

THE PROBLEM

Your digital core was built for people. It now has to be ready for AI.

Contracts, research, case files, policies and records hold the knowledge that guides daily decisions. It lives across file shares, applications, mailboxes and cloud tools, each with its own access rules.

Meanwhile AI is adopted faster than it is governed. Teams paste data into external services, nobody holds a complete inventory, and answers cannot be traced back to a source. AI cannot be trusted with information that has not been connected, classified and controlled.Your knowledge lives across file shares, applications and mailboxes, while AI is adopted faster than it is governed.

What sDEN does

Enterprise AIwith sDEN

Better answers. Data that stays yours.

A governed knowledge graph connects the systems where your knowledge lives, so private models reason over the right context, on premise, in a private cloud or in a hybrid setup. Every answer links back to its source, permissions follow the data, and your teams keep the data, the configuration and the knowledge to run it.A governed knowledge graph connects the systems where your knowledge lives, so private models reason over the right context.

PRODUCTS

Two Paths to Sovereign AI

  • sDEN Foundation

    Unify the data your teams already depend on.

    Connect your systems into one governed knowledge graph and run private AI on it, so people find what they need, data stays governable and AI gives answers you can trace.Connect your systems into one governed knowledge graph and run private AI on it, with answers you can trace.

The platform

One governed platform, from source to answer.

Connect your sources, structure what they hold and put it to work, inside an environment you control.

Connect your sources.

Work with the repositories your teams already use. Browse the connector catalog, start a sync and follow its files through each stage, then renew a connection that needs attention.

What makes sDEN different

Evidence-first, sovereign, governed

  • Source-cited answers

    Answers cite their sources, so teams can check the evidence.

  • Sovereign deployment

    Keep repositories, identities and controls in your own environment.

  • Expert-governed knowledge

    Experts review the knowledge that critical decisions depend on.

TRUST

Enterprise Security and Control

Stay in control

sDEN deploys inside your environment, so data stays where it is and established permissions continue to apply. Models run privately, and every request passes through one governed gateway that records what happened.sDEN deploys inside your environment: data stays where it is, models run privately and every request is recorded.

Secure by design

  • ISO/IEC 27001
  • SOC 2 Type 2
  • On premise, private cloud or hybrid
  • SSO and MFA
  • Encryption and managed keys
  • Audit trail for every AI request
  • Private models

For leaders who need control at the speed of AI

What is sDEN?

sDEN audits, designs and integrates sovereign information systems and private AI for large enterprises, public institutions, governments and regulators, and transfers the capability to operate them.

What is AI sovereignty?

AI sovereignty is the ability to decide and enforce how AI is used in your organization: which data it can reach, which models run where, under which law, and who can change or stop it. It combines jurisdiction, control of data and keys, choice of models and providers, and the internal capacity to operate the systems. It is not a product you buy. It is a set of technical, contractual and organizational decisions that keep authority with you as your use of AI grows.

Does sovereign mean on-premise only?

No. On-premise is one option among four: a private cloud in a European region, your own cloud account with keys you hold, your data center, or a fully air-gapped environment. The right level depends on the sensitivity of the data, your obligations, performance needs and the team available to operate it. Many organizations combine levels, keeping the most sensitive workloads closest. What matters is that the choice is deliberate, documented and reversible, rather than decided by default by a provider.

What is a governed knowledge graph?

We build a knowledge graph inside your environment that links the people, organizations, places and documents scattered across your systems, so every AI answer starts from resolved, connected facts.

Can we keep using frontier models?

Yes, under policy. A governed gateway can route each request according to rules you define: sensitive content goes to private models inside your perimeter, while approved, lower-risk tasks may use external frontier models under contract. Redaction, logging and approval rules apply on every path. This hybrid routing keeps access to the best available capability without letting it become the default for confidential data. The routing rules are yours, documented, and can change as models, providers and regulation evolve.

What does sDEN hand over at the end?

The aim is that you can run the system without us. Handover typically includes the architecture documentation, the configuration of the gateway and policies, the register of AI systems, runbooks, access arrangements, recovery procedures and escalation paths. Named internal owners are trained during delivery, not after it. Ownership, licenses, repository access and operating responsibilities are agreed contractually, distinguishing custom work, pre-existing materials and third-party components. Support after handover is optional and scoped separately.
