Home Office

The Home Office is one of the UK government’s most critical departments, responsible for national security, immigration, policing, and public safety. With complex infrastructure spanning AWS, Azure, and on-premise environments, they were under pressure to complete a wide-reaching automation programme across networks, core infrastructure, and private hosting capabilities.

The challenge was not only technical, but also cultural: they needed a partner to assess existing tools and practices, implement secure and scalable automation, and shift their delivery approach towards Agile and DevOps. In parallel, upskilling internal teams and embedding sustainable ways of working were key to ensuring long-term success and operational resilience.

“If you migrate to the cloud, you’ve got to take your employees with you on that journey. It’s vital that you take a proactive and ongoing approach towards training your employees” – James Carnie, Co-founder & CTO

Mobilise delivered a comprehensive transformation programme, combining cloud strategy, security automation, and team enablement to support the Home Office’s infrastructure goals.

  • Cloud migration & assessment: Reviewed existing tooling and infrastructure across AWS, Azure, and on-prem, aligning a roadmap with the department’s cloud strategy.
  • Security platform deployment: Designed and delivered HOVIS, a platform for deploying CIS-Hardened images securely across environments using automation.
  • Agile & DevOps culture: Embedded Agile practices and DevOps principles, improving delivery, incident response, and operational resilience.
  • Upskilling & knowledge transfer: Ran hands-on workshops, created technical documentation, and used a 'train-the-trainer' model to build lasting internal capability.

 

As a result, the Home Office strengthened its security posture, increased cloud capacity, and adopted a more product-centric approach, positioning itself for sustainable innovation and efficient service delivery.
