What Is a Sovereign Cloud?

Sovereign cloud is a type of cloud infrastructure that’s fully developed and operated within the jurisdictional boundaries of a specific nation or geographical region, with the data complying with the nation’s laws and governance.

When your data is stored in a sovereign cloud, you’re guaranteed complete legal, operational, and digital sovereignty.

Private hosting solutions that go above & beyond

Just three steps to total sovereignty.

Hyperscalers are built for everyone. We are built for you. Here is what that looks like in practice.

We build it around you

We design your environment around your stack, your compliance requirements, and your team. Not a template. Not a shared pool with your name on it. Infrastructure that is yours from the ground up.

We manage it for you

24/7 monitoring, proactive issue resolution, and a 15-minute expert response time. We catch problems before they reach you. When something does need attention, a named engineer picks it up.

You stay in control

UK data centres. Static monthly billing with no consumption penalties. Compliance by design, not bolted on after the fact. You know where your data is, what it costs, and who is responsible for every part of it.

Data Residency Versus Data Sovereignty

Data Residency

States where your data is stored. It ensures your data is stored securely in a defined geographic location.

Data Sovereignty

States which nation’s laws govern your data. It guarantees storage in a specific location and is subject to the laws of that nation.

If you host your data in a UK data centre owned by an overseas provider, it may still be subject to foreign laws.

BlackBox Hosting ensures both data residency and sovereignty. Your data resides on UK soil and is legally protected under stringent UK law and regulations, managed by a UK-owned and operated firm.

Your Questions Answered

What’s the difference between private cloud hosting and sovereign cloud hosting?
