Core service areas

Partners & investors

Structural demand, a twenty-year record, and a differentiated sovereign position.

The UK sovereign cloud market is estimated at c. US$13.7bn in 2026. The Ministry of Defence — the UK public sector's largest hyperscale cloud spender at c. £1.09bn — has committed £400m to a UK sovereign, air-gapped defence cloud. Secure by Design is mandated across MOD and expanding across government. And 52% of UK business leaders report actively seeking to repatriate data to UK jurisdiction.

TIS sits at the intersection of three procurement forces: sovereignty (jurisdiction), Secure by Design (evidence) and resilience (continuity) — with an advantage most challengers lack: two decades of delivery history and sector breadth from defence to offshore energy. Our position is sovereign-grade capability at specialist speed, without big-SI cost or conflicts.
