REAL-TIME INFORMATION
During each sweep, our team utilises advanced counter-surveillance techniques and procedures capable of identifying, analysing, and pinpointing eavesdropping devices within your environment. You will receive real time data and updates throughout the event, giving immediate insight into any suspicious transmissions, unauthorised devices, or vulnerabilities detected on-site. This feedback ensures you’re fully informed at every stage of the process, enabling swift decision-making and enhanced situational awareness.
PERCEPTION ENABLED
Our Perception Enabled approach means we don’t just rely on machines — we combine advanced technology with expert judgement to spot anything out of place. This allows us to detect even the most discreet or unusual threats, including devices that are switched off or only active at certain times. By looking beyond the obvious and understanding the environment as a whole, we provide a deeper level of protection and reassurance that your space is secure.

Heritage
Our Lightweight TSCM Incident Response (L)TIR service traces its heritage to the Lightweight Reconnaissance Network (LWRN) Teams, developed by 30 Signal Regiment as part of the British Army’s SPEARHEAD role in support of the Ministry of Defence’s Permanent Joint Headquarters (PJHQ).
​
These teams were built for rapid global deployment - within 24 hours - delivering agile and secure communication services to high risk environments.
​
Proven under pressure and deployed worldwide, including to West Africa, the Middle East, and across the UK, this capability was rigorously stress-tested in live operational settings.
​
Today, that same ethos of speed, discretion, and technical precision is embedded in every LIR(T) operation. We continue to support high-level clients with regular taskings across:

-
Switzerland
-
USA
