Cyber resilience for Critical National Infrastructure

Critical National Infrastructure organisations face increasing cyber risk driven by evolving threats, tightening regulation and ageing IT and OT systems. Cyro Cyber is a dedicated cyber security business jointly created through a partnership between Telent and experienced cyber security leadership, bringing together over 50 years’ combined experience in delivering cyber security services. Since 2022, Cyro Cyber has been helping organisations protect essential services with practical, proportionate and cost-effective cyber security.

Meeting today’s cyber security challenges

Operators of essential services are under growing pressure to demonstrate cyber resilience while maintaining operational availability and safety.

Legacy systems and technical debt

Ageing infrastructure never designed with cyber security in mind.

A practical approach to cyber security

Cyber security is often driven by technology‑led solutions that add complexity without delivering lasting assurance. Cyro Cyber takes a different approach.

We put people and process first, designing cyber security around how infrastructure is built, operated and maintained. By aligning risk appetite, regulatory obligations and operational reality, Cyro Cyber helps Telent clients create cyber resilience that works in live environments.

From board‑level strategy through to operational delivery, Cyro Cyber focuses on outcomes, not tools.
