Built to keep running
Government-assured colocation designed to keep your information available, accurate and secure. Our approach is built on internationally recognised standards, rigorous operational controls and transparent governance.
Resilience starts with your data
Protecting information assets is the reason ISO/IEC 27001, the international standard for information security management, exists. It sets out a risk-based framework for managing and protecting data, and defines resilience through three principles: availability, integrity and confidentiality.
Crown Hosting provides government-assured colocation designed to safeguard your information assets against all three. We are centrally assured by the GCA Framework Authority, with specialist support from the Cabinet Office, the National Protective Security Authority (NPSA) and the National Cyber Security Centre (NCSC), and offer NPSA, MOD DE&S and HMG-assured security.
How does Crown Hosting support your resilience?
Resilient power and cooling
A/B power paths, UPS systems and on-site generators with 72-hour fuel autonomy keep your services running. Our facilities meet BS EN 50600 availability class 4 requirements.
High service levels backed by service credits
99.999% power uptime and 99.995% environmental uptime, backed by service credits and transparent KPIs.
Cyber security
Crown Hosting and its delivery partners hold ISO 27001 and Cyber Essentials Plus certification. Industrial systems are IT Health Check and CHECK tested, and Cabinet Office assured using NPSA, NCSC and MOD DE&S.
Network diversity from multiple carriers
Carrier-neutral facilities with multiple meet-me rooms and multiple fibre routes for diversity. 99.9% SLA for single route WAN services and 99.99% for diversely routed connections.
Business continuity
Our certified ISO 22301 Business Continuity Management System underpins tested recovery and resilience processes.
24/7 on-site support
Remote hands, intelligent hands and project work, delivered on site around the clock by the team that owns and operates the facilities.
Keeping your services running
Your data is only as available as the infrastructure it sits on. Keeping it available when something fails depends on redundancy and no single point of failure, from duplicated and backed-up storage through to two or more geographically separate data centres housing your IT.
Availability is a particular speciality of Crown Hosting. Every one of our data centres benefits from the resilient power, cooling, connectivity and on-site support set out above.

Protecting against unauthorised change
Data integrity means your information stays accurate, complete and unaltered throughout its life, so it remains reliable for decision making. It can be lost through human error, hardware or software failure, cyber security events or failed data processes.
Protecting integrity is hard without the right skills and tools. Crown Hosting is a shared service, so the smallest public sector organisation benefits from the same expertise as the largest. Operating at that scale lets us apply best practice and proven technology at low cost, in areas individual organisations have often struggled to invest in.
Physical security
Preventing unauthorised access to your data
Only trained and authorised people are permitted on site, which helps stop logical cyber security being bypassed and reduces the risk of human error.
A robust and highly visible layer of protection strongly deters malicious actors, and makes it far more likely they are detected before they can reach your IT infrastructure.
Controlled environment
A stable environment for your IT
Tight control of the temperature and humidity in the data halls that house your IT infrastructure helps prevent unexpected hardware and software failures.
Best practice installation of your IT infrastructure helps prevent human error.
Preventing unauthorised access
Data confidentiality means sensitive information is only accessible to authorised people or systems. It prevents unauthorised access, disclosure or alteration of your data, and protects privacy and trust.
Across the public sector, physical security has too often been treated as an afterthought. Anyone who can reach your IT infrastructure unimpeded can have unrestricted and largely undetectable access to your data.
Crown Hosting has the scale and remit to apply the highest UK Government security standards required for the data held in our data halls, and to do so at very low cost. The security we apply is suitable for all security classifications, all threat levels and all levels of national criticality.
