The problem

European public sector communications face critical sovereignty challenges

Commercial tools limit sovereignty and control: Public cloud and commercial messaging tools can restrict data sovereignty and control, impacting compliance under European jurisdiction.

Fragmented tools prevent unified European operations: Each agency using different platforms blocks real-time collaboration across borders and between institutions.

Legacy systems block digital transformation: Outdated communication infrastructure prevents secure collaboration while failing to meet modern NIS2 and GDPR standards.
