Our AI practice
Ethical Sovereign AI
Sovereign by architecture. Ethical by design.
AI that runs inside your perimeter — on infrastructure you own — and can prove how it behaves. No data egress. No hidden model behaviour. Governed to ISO 42001 and aligned to the EU AI Act. Built for regulated organisations across the United Kingdom and Europe.
Most AI tools ask you to send your data somewhere else and trust what happens to it. Ethical Sovereign AI inverts that. The model comes to your data — not the other way round — and every decision it makes is logged, bounded and auditable. You get the capability without surrendering control, and you can prove it to a regulator, a client or your own board.
Where sovereignty is won or lost
The whole chain stays inside your boundary.
Data, model, inference and delivery all sit on infrastructure you control. The path that would carry your data to a foreign provider is severed at your perimeter.
What the name means
Two commitments, proven three ways.
We do not ask you to take "ethical" and "sovereign" on faith. Each one is something we build in and hand you the evidence for.
Sovereign by architecture
Where it runs.
- — Models, vector store and interface on hardware or in a cloud account you own.
- — Zero data egress — your data never leaves your perimeter or your jurisdiction.
- — Apple Silicon, NVIDIA on-premise, or a dedicated private cloud (AWS Bedrock, Azure OpenAI). Your choice, not ours.
- — No third party trains on your data. Ever.
Ethical by design
How it behaves — and how you prove it.
- — Every prompt and response logged to immutable, audit-ready records.
- — Defined authorisation boundaries: the system can only reach the tools and data you grant it.
- — Bias, safety and red-team testing before go-live, documented as evidence.
- — Explainable decisions — no hidden model behaviour your auditors cannot inspect.
Governed to standard
How it stays accountable.
- — An AI Management System (ISO 42001:2023), run by our GRC practice — not bolted on later.
- — Risk register mapped to EU AI Act risk categories and NIST AI RMF.
- — DPIA and AI risk assessment delivered with the deployment, not after it.
- — Owned by a named person, reviewed on a defined cadence.
Where are you now
Four levels, from dependent to sovereign.
Most organisations sit at level 0 or 1 without realising it. We assess where you are, then build the shortest defensible path to the level your regulators and clients expect.
Why now
The regulatory tailwind is already here.
The EU AI Act is phasing in obligations through 2025–2027. UK GDPR and the ICO already expect demonstrable control over personal data. Across Europe, data residency and digital sovereignty have moved from preference to procurement requirement.
Firms that adopt AI the convenient way — by piping confidential data to a US cloud — are quietly accumulating risk they will have to unwind. Ethical Sovereign AI lets you adopt the capability once, correctly: inside your jurisdiction, on infrastructure you control, with the governance evidence built in from day one.
The convenient way, and the sovereign way.
Public AI service
- Your data leaves your organisation.
- It sits in a jurisdiction you did not choose.
- You cannot see or keep the logs an auditor will ask for.
- Terms, models and behaviour can change under you.
- "Trust us" is the only assurance on offer.
Ethical Sovereign AI
- Your data never leaves your perimeter.
- It stays in your jurisdiction, on infrastructure you own.
- Every interaction is logged as compliance evidence.
- You control the model, the version and the policy.
- Auditable by design — you can prove all of the above.
Why Fox&Stack
Anyone can run a local model. Few can govern it.
Deploying an open-weight model is the easy part. Making it defensible is the work — and it is our specialty. Cyber security is our core. We deploy your AI sovereign, secure it as the cyber consultancy we are, govern it with a GRC practice built for ISO 42001 and UK regulators, and hand you the audit evidence to prove all three. One team, not four suppliers.
How we deliver it
Four ways in.
Sovereign RAG
Retrieval-augmented generation across your documents, fully on-premise or in your private cloud. Zero data egress, audit-ready logs.
Ethical AI Sandbox
An auditable piloting framework for regulated environments. DPIA, AI risk assessment and EU AI Act mapping delivered with the pilot, with a clear go / no-go before scale-out.
AI Governance (ISO 42001)
Build the AI Management System the EU AI Act and UK regulators now expect — charter, policies, roles and an AI-specific risk register.
Local AI Stack
Sovereign deployment on hardware you own — single-node Apple Silicon or NVIDIA — for teams that want speed without surrendering control.
Questions buyers ask.
What is Ethical Sovereign AI?
Ethical Sovereign AI is artificial intelligence that runs inside your own perimeter — on hardware or in a cloud account you control (sovereign) — and that can prove how it behaves through immutable audit logs, defined authorisation boundaries and pre-deployment safety testing (ethical). Fox&Stack governs it to ISO 42001 and aligns it to the EU AI Act.
How is it different from using ChatGPT or a public AI service?
With a public service your prompts and documents leave your organisation and sit on infrastructure you do not control, in a jurisdiction you may not have chosen. With Ethical Sovereign AI your data never leaves your perimeter, no third party trains on it, and every interaction is logged as compliance evidence.
Does it satisfy the EU AI Act and UK GDPR?
It is designed to. We deliver a DPIA, an AI risk register mapped to EU AI Act categories and NIST AI RMF, and an AI Management System built to ISO 42001. Data residency and no-egress architecture address the GDPR and UK GDPR concerns that drive most sovereignty requirements.
