TSCM — Technical Surveillance Counter-Measures
Professional detection, location, and neutralization of unauthorized surveillance devices. Protection of sensitive information, personal privacy, and intellectual property.
TSCM (Technical Surveillance Counter-Measures) are technical countermeasures against eavesdropping — a specialized process in which we detect, locate, and neutralize unauthorized surveillance devices before they cause harm.
What's at stake: Sensitive business information, strategic decisions, personal privacy, or intellectual property. A single compromised piece of information can cost a company millions or destroy someone's personal life.
What TSCM services mean in practice
Professional TSCM is not just about waving a detector around. It is a comprehensive, systematic approach combining cutting-edge technology, deep technical expertise, and hands-on experience with real cases of industrial espionage.
Detection and location
We use specialized tools to find every type of eavesdropping device — from analog to digital — transmitting across various frequencies, including encrypted or frequency-hopping devices.
Threat identification
The goal is to identify and disable every electronic eavesdropping system used to intercept confidential information — from classic microphones to sophisticated GSM listening devices or laser audio surveillance.
Securing the premises
We carry out inspections in offices, meeting rooms, vehicles, homes, and other spaces so that sensitive business information, strategic decisions, or personal data are not compromised.
Protecting intellectual property
TSCM services also protect companies' intellectual property — development projects, business strategies, contract negotiations — and ensure comprehensive information security.
What devices we can detect
→ Audio eavesdropping devices — wired and wireless microphones, GSM bugs, laser audio surveillance
→ Video surveillance — hidden cameras (Wi-Fi, RF, wired), pinhole cameras, modified everyday objects
→ GPS tracking — tracking of vehicles and people, battery-powered and hard-wired trackers
→ Compromised electronics — modified phones, computers, chargers, USB devices
→ Network attacks — unauthorized Wi-Fi connections, man-in-the-middle attacks, network tapping
→ Telephone eavesdropping — compromised phone lines, PBX systems, VoIP interception
→ Modifications to the premises — devices hidden in outlets, lights, furniture, decorations
→ TEMPEST attacks — capturing electromagnetic emissions from computers and monitors
When TSCM services are essential
Typical situations that call for a TSCM inspection:
✓ Sensitive business negotiations — M&A transactions, strategic partnerships, pricing talks
✓ Protection of development projects — new products, technologies, design, R&D
✓ Legal disputes — divorces, inheritance disputes, business conflicts
✓ Suspicion of information leaks — competitors know too much, unauthorized disclosure of data
✓ Preventive inspections — regular audits of important premises, ahead of major events
✓ Personal security — VIPs, senior executives, at-risk individuals
How a professional TSCM inspection unfolds
Phase 1: Preparation and planning
A discreet preliminary consultation, risk analysis, planning of the inspection's scope, and timing of the inspection for minimal disruption to operations.
Phase 2: Physical inspection
A detailed visual inspection of all areas, furniture, technical equipment, and hidden spots using endoscopes, a borescope, and special lighting techniques.
Phase 3: RF spectral analysis
Comprehensive scanning of the radio-frequency spectrum from kHz to GHz to detect all types of wireless transmitters — analog and digital alike.
Phase 4: NLJD scanning
A Non-Linear Junction Detector reveals electronic devices even when they aren't transmitting — finding hidden chips and electronics in walls and objects.
Phase 5: Telecommunications inspection
Analysis of phone lines, PBX systems, and VoIP communication, and detection of parallel connections or wiretaps.
Phase 6: Network analysis
Inspection of computer networks, Wi-Fi, and connected devices, and detection of unauthorized access or network attacks.
Phase 7: Technical documentation
A detailed written report on all findings and methods used, photographic documentation, and recommendations for security measures.
Phase 8: Recommendations and prevention
Specific guidance on strengthening physical and technical security, training staff, and setting up preventive procedures.
Why TSCM is an essential professional service
Amateur attempts to detect surveillance devices are like searching for a needle in a haystack blindfolded. Professional surveillance technology today is extremely sophisticated — digitally encrypted, frequency-hopping, remotely controlled, or entirely passive.
TSCM requires an investment in specialized equipment worth millions of crowns and years of practical experience. Our technicians are certified specialists with backgrounds in counterintelligence and technical security.
Protect your information before it's too late
Once information is compromised, it can never be taken back. Prevention is always cheaper than dealing with the consequences.
