Counter-surveillance Switzerland
Do you suspect that your conversations are being tapped or your location tracked? Spygroup.ch offers advanced TSCM (Technical Surveillance Counter-Measures) services and GPS tracker detection. We operate discreetly throughout Switzerland.
Protect your business and privacy in Switzerland
Nowadays, business and private surveillance is easier, cheaper, and more widespread than ever before. Miniature bugs, hidden cameras the size of a pinhead, and advanced spyware are available to anyone online. Professional eavesdropping defense (also known as counter-espionage or TSCM – Technical Surveillance Counter-Measures) is the only effective way to regain control. Our technical security audit is a comprehensive service that includes protecting premises from the following threats:
Active radio and GSM listening devices.
Hidden cameras (wired and wireless).
Inactive («dormant») recording devices.
GPS tracking devices in vehicles.
Listening devices in the power and telephone networks.
Effectively locating bugs and protecting information is not an expense—it is an investment in the peace of mind and security of your business.

How do we proceed?
Technical surveillance countermeasures (TSCM) is a complex, multi-stage process. Our methodology guarantees the detection of any espionage device, regardless of whether it is active or inactive.
Four-step process of counterespionage:
- Radio frequency (RF) detection: Environment scan using spectrum analyzers to locate active signals (GSM, Wi-Fi, bugs).
- Electronic detection (NLJD): Detection of inactive and hidden devices (dictation devices, cameras) using nonlinear junction detectors.
- Visual and thermographic inspection: Physical search of rooms, installations, and vehicles, supported by thermal imaging cameras.
- Network monitoring: Analysis of the security of computer, telephone, and power networks for wired listening devices.
Professional equipment Spy Group
Premium technology in the service of safety.
Detecting listening devices, GPS trackers, and hidden electronic devices requires the use of precise, certified equipment. Spy Group has a complete technological base that enables the detection of radio emissions, the investigation of digital signals, the analysis of wireless networks, and the identification of devices hidden in walls, furniture, and vehicles.
Spectrum analyzers and radio systems
- Signal Hound BB60C – Real-time spectrum analyzer with a range up to $6 GHz $. Used for locating and identifying radio transmissions, analyzing signals with variable modulation, and detecting hidden transmitters.
- Aaronia SPECTRAN – mobile spectrum analyzer with high sensitivity, which works with the RTSA Suite PRO software. It enables real-time analysis, the creation of frequency maps, and the rapid location of RF emission sources.
Nonlinear junction detectors (NLJD)
- ST-402 Cayman – professional non-linear transition detector used to locate semiconductor elements hidden in walls, furniture, and appliances.
- Piranha ST-31 – a modern NLJD detector that detects even switched-off listening devices and electronic circuits that do not emit a signal.
💡 NLJD detectors enable you to find hidden microphones, recording devices, and tracking devices, even when they are not active.
Signal detectors and RF protection devices
- ST-167 – Broadband detector for GSM, Wi-Fi, Bluetooth, LTE, and DECT transmissions. Enables quick localization of active spy devices in rooms and vehicles.
- ST-500 – Analyzer and detector for electromagnetic threats that detects anomalies in the radio frequency range, pulse signals, and hidden digital transmissions.
Network and data transmission analysis
Alfa AWUS036ACH + Acrylic WiFi LEA – professional kit for monitoring Wi-Fi networks, enabling the detection of unauthorized access points, hidden IoT devices, and Wi-Fi cameras.
Wireshark – advanced software for analyzing data packets, used to examine network traffic and identify devices that are communicating secretly.
Forensic systems and mobile device analysis
- Cellebrite / UFED – Police-grade system for analyzing, extracting, and recovering data from mobile phones. Used in forensic IT reports.
- Test phones Android/iOS – dedicated devices for simulating attacks, security testing, and analyzing spyware.
Auxiliary and inspection equipment
FLIR E6 camera – Thermal imaging camera used to locate active heat sources, hidden cables, and electronic components. It facilitates the detection of listening devices with their own power supply and transmission circuits.
- Inspection cameras/inspection endoscopes – used to examine areas that are difficult to access, such as cable ducts, the interiors of furniture, or false ceilings.
About us
SpyGroup is a globally active team of specialists in business security and data protection. We specialize in detecting listening devices (TSCM), securing meetings, and conducting comprehensive security audits—including cars, yachts, offices, apartments, and houses. We operate throughout Europe, the UAE, and other countries; our experts are ready to travel anywhere in the world to conduct a thorough inspection.
Our approach
We handle every job methodically and with complete professionalism. The checks we carry out are not a „quick visit“ – where necessary, we perform multi-stage and long-term analyses (e.g., a detailed check of a car in $24$-hour mode) to ascertain the actual condition and rule out any possible manipulation. We conclude each audit with a transparent report, conclusions, and recommendations for further action.
Team and equipment
Our specialists are practitioners with extensive technical experience, including former special service officers and digital forensics experts. We have modern, professional equipment and premium software at our disposal—we can operate it efficiently and apply it practically, ensuring that investigations are reliable and meaningful.
What we check
- Detection of listening devices and tracking devices (RF, GSM, GPS, BLE, hidden devices)
- Securing and supporting confidential meetings and negotiations
- Inspections of cars and yachts (including several hours of monitoring and analysis)
- Comprehensive audits of office spaces, apartments, and houses
- Analysis of phones and mobile devices, as well as technical advice on privacy protection
Confidentiality and professionalism
We operate in compliance with the highest standards of confidentiality and ethics. All activities are carried out in accordance with applicable legal provisions and the principles of information security. Customer trust and discretion are our top priorities.
