Sovereign Cloud Deployment
Compliant sovereign cloud environments, designed and delivered for defence, government, and regulated industries.
Sovereign cloud environments built to meet your compliance obligations from day one.
AWS, Azure, and Google Cloud each offer sovereign cloud solutions, but a sovereign cloud platform alone does not guarantee compliance.
How your environment is architected, configured, and governed determines whether it actually meets your obligations. We design and deploy sovereign cloud environments built to your specific requirements, delivered by SC/DV-cleared personnel aligned to Secure by Design, JSP 440, and JSP 453.
Landing Zones: Sovereign cloud foundations built to JSP 440 and JSP 453 for MOD bodies and Defence Primes
Enclave Architecture: Design and deployment of access enclaves for sensitive and classified workloads
Secure by Design: Cloud environments delivered to the latest UK Defence mandates from day one
Defence & National Security
Healthcare & Highly Regulated Public Sector
Clinical Data Infrastructure: Sovereign cloud environments built to NHS and health sector data residency requirements

Not Every Cloud Partner Can Build for Sovereignty
Sovereign cloud delivery requires the right clearances, the right frameworks, and genuine experience of the environments your organisation operates in.

Our Sovereign Cloud Assurance Methodology
-
We start by establishing the "Ground Truth" for your cloud environment. This ensures your technical architecture is aligned with your specific mission and legal obligations.
Requirements Mapping: Defining data sensitivity and classification needs.
Regulatory Alignment: Identifying specific sovereignty and JSP mandates.
Governance Review: Auditing organizational structure and decision ownership.
Platform Audit: Assessing the cloud platforms and environments currently in use.
-
We conduct a deep-dive assessment into how your environment actually operates versus its original security design.
Segmentation Audit: Verifying how data is governed and isolated across environments.
Boundary Validation: Testing how security boundaries are defined and enforced in practice.
Control Application: Reviewing how governance is maintained as the environment evolves.
Drift Identification: Pinpointing where complexity or unmanaged risk has deviated from JSP 453 or Secure by Design mandates.
-
You receive a comprehensive, defensible report designed for use with senior leadership, boards, and external regulators.
Compliance Posture: Clear evidence of how current arrangements align with JSP 453, Secure by Design, and UK data protection obligations.
Assurance Evidence: Independent verification of where controls and boundaries are operating effectively.
Risk Gap Analysis: A RAG-rated assessment highlighting specific areas of ambiguity or unmanaged Sovereignty Gaps.
Remediation Roadmap: A prioritised action plan for addressing gaps and maintaining your Permission to Work.
Evidence in Practice: Establishing Cloud Governance for UK Defence.

Delivering a Defensible Path Forward
The Sovereign Cloud Assurance Review is designed to provide you with a clear, evidence-based starting point. What happens next depends entirely on the findings and your organisation’s specific priorities.
Where issues or areas of concern are identified, you typically choose one of three paths:
Internal Resolution: Address any identified gaps using your existing internal teams or current suppliers.
Specialist Support: Engage Defended Solutions to support the remediation or change process.
Independent Baseline: Use the review as an independent, third-party baseline while remediation is delivered by another provider.
In all cases, the review provides a clear starting point for next steps without locking your organisation into a particular delivery model.
An Independent Standard of Assurance
Our methodology is grounded in the latest UK Government and Defence standards. We operate as an independent partner, ensuring your cloud architecture remains compliant with the evolving security landscape.
All engagements are led by UK-resident, National Security Vetted (SC/DV) personnel.
