Vault Cloud UK is building high-assurance cloud infrastructure for defence, government and critical national infrastructure — UK-owned, UK-operated, and subject to UK jurisdiction alone.
A cloud is only as sovereign as the law it answers to. Vault Cloud UK is structured so that one jurisdiction — the United Kingdom — governs our infrastructure, our operations, our people and our company. No foreign ownership. No offshore control plane. No legal reach from elsewhere. For the workloads the nation depends on, that is not a preference. It is the requirement.
Compute, storage and networking engineered for sensitive workloads — isolated by design, encrypted throughout, and administered only from within the UK.
