Technical Surveillance Counter Measures : TSCM
Delivered by specialists with backgrounds in UK Special Forces, government, and defence, ensuring the highest professional standards.
S2K provide discreet, high-level Technical Surveillance Counter Measures (TSCM) operations for private, corporate, and legal-sector clients across the UK. Also known as electronic bug sweeping, TSCM involves the detection, identification, and neutralisation of illicit surveillance devices, from covert audio bugs and hidden cameras to GPS trackers and wireless transmitters.
