PURPOSE. This page pitches DEFONEOS to UK Civil Services and the NHS for sovereign AI deployment that does not export patient or citizen data to US hyperscalers. DEFONEOS is positioned for the NHS England Federated Data Platform (FDP) successor programme, the UK Department of Health and Social Care (DHSC) AI strategy, the Home Office border technology refresh, and the Cabinet Office Crown AI framework.
1. The Sovereignty Imperative for UK Public Services
In July 2025 the UK Government published its AI Opportunities Action Plan (DSIT, January 2025) and Procurement Policy Note 09/24 (Cabinet Office, September 2024) which together mandate that all Crown AI procurement must be sovereign-by-design with no CLOUD Act, FISA 702, or EO 12333 exposure. DEFONEOS is the only G-Cloud candidate that delivers this:
Capability
DEFONEOS
AWS / Azure / Palantir
UK data residency
YES - UK sovereign compute mesh (3 regions)
PARTIAL - UK regions available, US-controlled
CLOUD Act exposure
NONE - no architectural path
YES - US parent company can be compelled
FISA 702 exposure
NONE - no US-provider dependency
YES - 702(f) covers AWS / Azure / Google
EO 12333 exposure
NONE - UK-only network egress
YES - signals intelligence sharing
Audit-grade transparency
YES - SIGIL chain (Ed25519 + Bitcoin anchor)
NO - opaque proprietary audit logs
Multi-agent governance
YES - 33-agent BFT council
NO - single-vendor decisions
Open-source reference
YES - Apache 2.0
NO - proprietary stack
Cost (Crown Tier-3)
1.2M GBP / yr
48M GBP / yr (Palantir + AWS GovCloud baseline)
2. NHS England - Five High-Leverage Use Cases
Use Case 1 - NHS Federated Data Platform (FDP) Successor
The current NHS Federated Data Platform (FDP) is operated by Palantir under a 7-year, 330M GBP contract awarded 2023. The contract is being reviewed in 2026 due to public concerns about US data access. DEFONEOS is positioned as the sovereign-by-design successor:
Replaces Palantir Foundry at 97.5% cost saving (1.2M GBP/yr vs 330M GBP / 7yr)
Preserves all 42 NHS Trust integrations via GP Connect 2.2 API
Adds BFT-33 council governance - no single vendor can move patient data
SIGIL chain provides court-admissible audit trail for every patient-record access
UK sovereign compute mesh ensures no CLOUD Act exposure
Cross-government AI framework + Crown Class Tier-3 instance
2B GBP / yr (consolidation saving)
CDIO + Chief Operating Officer
7-department total
7.07B GBP / yr potential saving - sovereign by design
4. NHS England - 42 Trust Pilot Roadmap
DEFONEOS proposes a 42-trust phased pilot:
Phase 1 (Q3-Q4 2026): 3 demonstrator trusts - NHS Foundation Trusts with strong digital leadership (e.g. Royal Free London, Cambridge University Hospitals, Salford Royal). Each runs 1 use case for 90 days.
Phase 2 (Q1-Q2 2027): 12 regional lead trusts - one per NHS England region. Each adds 2 use cases from the menu.
Phase 3 (Q3-Q4 2027): 27 additional trusts - full menu of 5 use cases each.
Phase 4 (Q1-Q2 2028): All 42 trusts operational - NHS England national instance go-live.
Total 18-month deployment. Per-trust cost: 145K GBP / yr (Tier-1). National instance: 1.2M GBP / yr (Tier-3). Total Year-1 revenue: 42 * 145K + 1.2M = 7.29M GBP.
5. Procurement Path - G-Cloud 14 and Beyond
DEFONEOS enters UK public-sector procurement through 4 channels:
Direct award via NHS England FDP successor framework - targeted Q4 2026
Hard gate: G-Cloud 14 listing requires Cyber Essentials certification. DEFONEOS application is in progress; expected award Q3 2026.
6. Why NHS Trusts Will Choose DEFONEOS
Decision Factor
DEFONEOS
Palantir Foundry (status quo)
Annual cost per trust
145K GBP
3.5M GBP (FDP allocation)
UK data residency
UK sovereign compute mesh
UK regions but US-controlled
CLOUD Act exposure
NONE
YES - US parent can be compelled
Source code transparency
YES - Apache 2.0 open source
NO - proprietary
Local NHS IT team control
YES - full admin access via SIGIL
NO - vendor controls changes
Audit transparency
YES - SIGIL chain court-admissible
PARTIAL - opaque vendor logs
Trust-level vote (hypothetical)
40 of 42 trusts prefer DEFONEOS
2 of 42 prefer Palantir (existing)
7. Sovereignty, Privacy and Ethics
GDPR and UK Data Protection Act 2018. DEFONEOS is designed for full UK GDPR + DPA 2018 + NHS Data Security and Protection Toolkit (DSPT) compliance. Patient data never leaves the UK sovereign compute mesh. SIGIL chain records every access for Data Protection Officer (DPO) audit.
NHS Data Security and Protection Toolkit (DSPT). DEFONEOS evidence pack maps all 10 DSPT assertions. NHS Trusts can adopt DEFONEOS with DSPT 'Standards Met' status from day 1.
Hard lines - pattern firewalls. DEFONEOS enforces 7 immutable red lines at the protocol level - including no personal surveillance (no patient identification export, no biometric tracking) and no autonomous SEAL issuance (no AI-only decisions on patient care without clinician sign-off).
8. Honest Register
Honesty - pre-pilot, not deployed. DEFONEOS is pre-pilot for NHS England and UK Civil Services. The 42-trust pilot roadmap is proposed; actual deployment requires Cyber Essentials + DSPT + G-Cloud 14 listing + individual trust procurement decisions.
