The UK's Sovereign Neo Cloud

Secure sovereign infrastructure for high-assurance environments

UK-owned, UK-operated cloud and AI infrastructure built for Defence, national security, critical national infrastructure and regulated industry — where jurisdiction, assurance and operational control are not negotiable.

Why Vault

Sovereignty is a jurisdiction, not a data centre postcode

Hyperscale infrastructure hosted in the UK is not the same thing as infrastructure the UK controls. Vault is built on the difference.

Sovereign by Jurisdiction

UK-owned, UK-operated and subject exclusively to UK law. No foreign parent, no extraterritorial reach over your data, and no ambiguity about who can be compelled to grant access.

Assured by Design

Architected to the NCSC Cloud Security Principles and MOD Secure by Design, operated by security-cleared UK personnel, with an information security management system built to ISO/IEC 27001:2022.

Built for AI Workloads

GPU-dense sovereign infrastructure for training and inference on sensitive data — the compute economics of a neo cloud, inside a UK assurance boundary.

Capabilities

Sovereign compute, from virtual machine to GPU cluster

01

Sovereign AI

Train, fine-tune and serve models on GPU infrastructure that never leaves UK jurisdiction — so sensitive data can be used for AI rather than withheld from it.

02

Enterprise Capacity

Secure infrastructure-as-a-service, high performance compute and hosting for enterprise and mission-critical workloads, scaled on demand.

03

Secure Connectivity

Protected gateways, cross-domain transfer and network security for organisations moving information between assurance boundaries.

04

Sovereign Platform

A hardened, Vault-maintained platform with its own release and patch line — engineered so that security control sits above the physical layer, not bolted on beside it.
