Fast-response counter-espionage bug sweep service for companies, lawyers, governmental institutions, financial and banking. 

Espionage is a real and growing problem in the UK and Europe. An estimated £21 billion per year in the UK alone is lost due to industrial espionage. It doesn’t just affect large companies – an increasing number of smaller organizations fall victim to industrial espionage, where their intellectual property turns up in the hands of their competitors.

Bug Sweep Equipment

Our technology, our training and the use of government laboratory grade equipment are considered the standard within our government and the governments around the world. The kind of equipment that we use includes spectrum analyzers, nonlinear junction detectors, broadband detectors and just a wide variety of devices and instruments to explore all possible capabilities that could compromise your privacy. Our equipment includes:


REI Oscor Green 24 Ghz – Spectrum Analyzer

The OSCOR Green Spectrum Analyzer is designed to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum. The OSCOR Green is a portable spectrum analyzer that sweeps 8/24 GHz in one second to quickly detect transmitting electronic surveillance devices and ensure that spectrum activity is captured.



Non-Linear Junction Detector (NLJD) finds potential eavesdropping devices in walls, fixtures, furniture, floors, ceilings, vehicle, or other surfaces. NLJDs are devices designed to detect and locate hidden cameras, microphones, and other electronic devices, in any operational mode: active, standby, turned off, radiating, or hard wired. NLJD technology has proven to be most effective in the detection of semiconductors containing multiple layers of silicon, a P-Type and an N-Type, and an essential piece of equipment for efficient “Bug Sweep”.

REI Countermeasures Line Sweeper and Amplifier

The high gain audio amplifier used to detect and identify surveillance devices attached to building wiring such as telephone wiring, LAN and server systems, AC Power, Alarm wire etc.

Thermal Emission Spectrum

A key piece of equipment to detect heat created by the electricity moving through the surveillance parasitic devices.

Physical Search & Inspection Equipment

Methods of inspection

TSCM survey (Bug Sweeping) is a specialized examination of an area or vehicle to detect, locate and identify any eavesdropping devices, up to TSCM Threat Level 9.

We specialize in identifying suspicious RF signals from VLF till 24 GHz, analog/digital and data transmitters, including Wi-Fi (2.4 & 5 GHz), GSM-UMTS-LTE.

After meeting you and evaluating the threat we conduct a quick inspection which allows us to establish the adequate Technical Investigation for your case.

After we have conducted the survey we report back to you on our findings, flagging up particular risks and making recommendations on how to ensure your privacy isn’t compromised.

Our team of professional technicians has vast experience in electronics and telecommunications, with years of military and law enforcement experience.
