BlackBox Hosting provides secure, sovereign cloud storage for UK businesses that need to keep their data protected, encrypted and entirely within British borders. Every file, database and backup is stored in our ISO 27001-certified Tier 3+ data centres in London, governed exclusively by UK law.
Unlike consumer storage platforms such as Google Drive or Dropbox, BlackBox cloud storage is built for businesses handling sensitive, regulated or commercially valuable data. Your storage environment is private and dedicated – not shared with other tenants.
| Feature | Detail |
| Encryption at rest and in transit | AES-256 encryption protects your data at every stage. No unencrypted data ever leaves the storage environment. |
| UK data residency guaranteed | All stored data remains within UK borders at all times – including backups and replicas. |
| Dedicated storage environment | Your storage is not shared with other customers. Isolated infrastructure reduces risk and gives you full control. |
| Access controls and audit logging | Granular role-based access controls with full audit trails for compliance reporting. |
| GDPR and regulatory compliance | Storage architecture designed to meet UK GDPR, NHS DSPT, PCI-DSS and FCA requirements. |
| No exposure to foreign access laws | As a UK-owned and operated provider, BlackBox is not subject to the US CLOUD Act or Patriot Act. |
BlackBox Hosting is a fully GDPR compliant cloud hosting provider. Our sovereign infrastructure is purpose-built to help UK businesses meet their obligations under the UK GDPR and Data Protection Act 2018 – not as an add-on, but as the foundation of how we operate.
UK-only data residency: All personal data is stored and processed within the UK. No data is transferred to, processed in, or accessible from any jurisdiction outside the UK.
UK-owned and operated: BlackBox is a UK company, operated by UK staff, from UK data centres. We are not subject to the US CLOUD Act, Patriot Act, or any non-UK data access legislation.
Data processing agreements: We provide comprehensive DPAs as standard, covering data processing activities, security measures, sub-processor disclosures and breach notification procedures.
Certifications that evidence compliance: ISO 27001, ISO 22301, Cyber Essentials Plus, CSA STAR Level 2. These represent independently audited processes that demonstrate your data is handled to the standards regulators expect.
Audit-ready infrastructure: Full access logging, encryption at rest and in transit, role-based access controls, regular penetration testing, and documented incident response procedures.
UK data residency means your data is physically stored within the United Kingdom. With BlackBox Hosting, data residency is guaranteed – every server, every backup, every replica sits within our Tier 3+ data centres in London. But residency alone is not enough. True data sovereignty also means the infrastructure is owned, operated and governed by a UK entity under UK law. BlackBox delivers both.
Every solution is custom-built to your requirements. No consumption penalties, no egress charges, no surprise invoices. Typically up to 50% cheaper than equivalent AWS or Azure configurations.
We’ll protect you from every threat
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.
