Defence

Secure by Design is the mandate. Evidence is the currency.

TIS has a long pedigree in delivering highly secure systems, services and consultancy within the defence sector — from open-source platforms through to complex systems at the highest classification levels. We design networks and infrastructure to a level capable of supporting the highest government and defence classifications, and we've been doing it for two decades.

Since 2023, MOD programmes carry security through-life: designed in, evidenced continuously, owned by the delivery team. That changed what defence buys from consultancies — not advice, but artefacts. TIS delivers the architecture, the control evidence and the operating discipline that standard demands.

What defence programmes get from TIS

• Secure architecture and zero-trust design with accreditation evidence
• Secure cloud infrastructure aligned to defence cloud requirements
• Independent testing — penetration through red team — under NDA and cleared handling
• Cyber Essentials and certification support for the defence supply chain
• Resilience planning for systems where downtime is an operational failure
