Critical National Infrastructure

CNI failure isn't an outage. It's a national event.

Energy, water, transport, health: the systems the country cannot function without are exactly the systems adversaries probe first and regulators inspect hardest. TIS brings two decades of delivery in adjacent hard environments — high-classification defence systems, offshore energy communications, aviation operations — to the protection of critical national infrastructure.

What CNI operators get from TIS

• Resilience and continuity planning as a first-class discipline — not an appendix
• Zero-trust architecture adapted for OT and legacy estates that can't simply be replaced
• Independent testing calibrated for environments where a scan can't take down a plant
• Secure cloud infrastructure with UK jurisdiction for operational data
• Communications resilience, including satellite, for remote and distributed assets
