For UK Public Sector

Sovereign AI, on UK-owned hardware. At a price that works at desk scale.

Government is leaving the incumbent stack for sovereignty. Government is adopting AI for productivity. Arsenale is the only product that does both, on UK soil, at a per-desk price comparable to a standard workstation refresh.

Four trends. One product.

Four directions of travel inside government IT are all moving the same way at once. Arsenale sits at their intersection — not by repositioning, but by construction.

Trend Where it shows up Arsenale
AI on every desk Productivity programmes across DWP, HMRC, MoJ, NHS commissioning. Knowledge-worker workflows are the next site of public-sector productivity gain.
Off the incumbent desktop Schleswig-Holstein migrating ~30,000 state workstations to Linux + LibreOffice. France's Gendarmerie Nationale on GendBuntu (~80,000 PCs). European Commission off Microsoft 365 post-EDPS ruling. UK Cloud-First posture under quiet re-examination.
Off the foreign cloud Citizen and case data cannot legally leave UK soil for benefits, tax, court, NHS or safeguarding workloads. Hyperscaler concentration risk flagged by NCSC.
Capex over opex Vendor cloud and licence costs up 20–40% across 2023–2025. Treasury squeeze on recurring software spend. Owned hardware pays itself back inside refresh cycle.

References to specific government bodies indicate workload categories that fit Arsenale's deployment profile. No claim of existing UK government contract is implied.


Per-desk economics

Sovereign AI fails the moment it is more expensive than the incumbent option. The honest comparison is not "AI vs no AI" — it is sovereign-by-default AI vs cloud AI on the existing fleet, vs an on-prem cluster build-out.

Per-desk, year one Cloud AI on existing PC On-prem cluster + new PC Arsenale per desk
Hardware ~£600 standard refresh ~£600 PC + cluster share £2,499 owned outright
Software / integration Y1 £288–360 / yr per seat £30k–80k integration + ops £1,200 / yr full stack
Sovereignty posture Data leaves UK soil Sovereign, complex Desk-local by default
Asset ownership Rented forever Cluster shared Owned outright
Vendor pricing risk 20–40% rises 2023–25 Cluster vendor lock Fixed at purchase
5-year per-desk total ~£2,040–2,400 + sovereignty risk £30k+ amortised + ops £8,499 sovereign + owned

Honest framing: Arsenale is more expensive than cloud-AI-on-existing-PC in raw cost. The premium buys sovereignty by default, ownership of the asset, fixed pricing for the life of the unit, and the ability to deploy AI to workloads where citizen data physically cannot leave the desk. For workloads where sovereignty is mandatory, the cloud option does not exist as an alternative.


International reference cases

The shift away from the incumbent desktop is not a UK-only signal. Comparable governments have published, funded, and begun executing the same migration.

Germany

Schleswig-Holstein

State government migration of approximately 30,000 workstations from the proprietary desktop to Linux and LibreOffice. Announced 2024, in execution. Stated motivations: licensing cost, digital sovereignty, vendor exit-cost.

France

Gendarmerie Nationale

Approximately 80,000 PCs on a custom Ubuntu derivative (GendBuntu), in production for over a decade. Cited by EU peers as the canonical proof that government desktops can run on Linux at scale without operational compromise.

European Union

European Commission

Migration off Microsoft 365 following the European Data Protection Supervisor's 2024 ruling that the platform did not meet GDPR transfer requirements. Replacement architecture explicitly favours sovereign and on-premise stacks.


What ships, per desk

A single appliance. UK-built, UK-shipped, UK-supported. Five years of operating-system security updates included from the day of installation. The annual licence covers new model versions, agent capability releases, and runtime upgrades.

Form factor Desk-side appliance, fan-quiet, standard 100–240V power
Inference 120-billion-parameter mixture-of-experts model on 96GB unified memory, 18 tokens per second
Cost-per-decision Under £0.01, unmetered
Data egress Zero by default. Air-gap supported.
Operating system Syntex OS — UK-developed Linux-based platform, hardened for sovereign deployment
Update channel Cryptographically signed OTA updates, hardware-bound licensing
Security commitment 5 years of OS security updates included from purchase. Annual licence extends past that horizon.
Procurement routes Direct purchase. G-Cloud listing in preparation. Framework supplier status to be pursued at next CCS Technology Services iteration.
