"Four Seals' support has been exemplary, spanning from new features to critical service recovery. Consistently met deadlines, remained within budget, and delivered high-quality outcomes.

ResilienceDirect™, cloud migration & platform modernisation

Migrated three mission-critical national services, Collaborate, JOL and Maps, from legacy private data centres to AWS London, under strict UK-sovereignty and Official-Sensitive controls. The platform is used 24/7/365 by emergency responders across the UK, so zero downtime was non-negotiable.

Delivery covered programme and technical project management, AWS solution design, Terraform-based infrastructure-as-code, a new AWS Cognito authentication layer, and real-time performance dashboards. The Cabinet Office publicly showcased the migration in its blog "Future-proofing the ResilienceDirect service by migrating to public cloud."

WordPress → Wagtail: a secure, scalable intranet for 12,000 users

Re-platformed a large central-government intranet from WordPress to Wagtail on Django, and reimagined the design across mobile, tablet and desktop. We preserved every editor group and approval workflow while cutting the attack surface, killing off redundant accounts, and shipping new capability, event calendars, watchlists, a simplified form builder and smart NLP-powered search.

The result: a lean, secure, low-maintenance CMS with predictable upgrade paths and ~60% lower hosting and infrastructure costs than the previous WordPress estate.
