The problem

Critical gaps in threat awareness expose UK public sector to unnecessary risk.

Commercial tools limit resilience and control: Public cloud and commercial messaging tools can restrict compliance and data control, impacting resilience and national security.

Fragmented workflows create operational silos: They introduce gaps in threat awareness and response coordination, blocking real-time collaboration across stakeholders, partners, and allies.

Legacy systems block digital transformation: Outdated communication infrastructure prevents secure collaboration while failing to meet modern 
UK GDPR and CSRB standards.
