Sovereign Cloud
Air-gapped and sovereign cloud platforms designed, built and handed over as an operating model — so data, keys and administration stay inside your own borders and your own staff can run it.
Defending digital sovereignty
Sovereign and air-gapped cloud, built and assured for organisations that cannot afford to lose control of their data.

What we do
Three capabilities, one outcome: you keep control.
We work with regulated and sovereignty-constrained organisations — government, defence, financial services and critical national infrastructure — from architecture through to a platform that runs.
Secure Infrastructure
Landing zones, identity federation, network policy and platform guardrails, designed against the controls your regulator, your auditor and your board already hold you to.
Quantum Readiness
Cryptographic discovery, exposure assessment and a sequenced migration to post-quantum algorithms — a plan with owners, costs and dates, not a slide about the threat.
How we work
Small team. Senior people. No handover to juniors.
-
Step 01
Assess
We establish what you actually have, what the requirement really is, and which constraints are regulatory rather than habitual.
-
Step 02
Architect
A reference architecture and a build sequence your team can cost, resource and defend in front of a design authority.
-
Step 03
Build & assure
We build alongside your engineers, prove the controls, and leave documentation that outlives the engagement.
Sovereign Cloud Defence is a UK company founded by three practitioners — Dr Samuel Mayes, Adam Wotherspoon and James McNulty — who build these platforms themselves.
