TSCM — Technical Surveillance Counter-Measures
Counter-surveillance sweeps for executive offices, board rooms, negotiation venues, and high-assurance environments. Discreet, on-site engagements delivered with calibrated detection equipment.
Why TSCM Matters
Sensitive commercial information — M&A negotiations, board deliberations, intellectual property strategy, executive personnel matters — is frequently the target of covert technical surveillance. Modern surveillance devices are small, inexpensive, often GSM/Wi-Fi/LoRa-enabled, and can transmit for weeks on a single battery. A periodic TSCM sweep validates that the environments in which your most sensitive conversations occur are not actively compromised.
Sweep Methodology
- Pre-engagement intelligence — quiet site reconnaissance, threat-actor assessment, and operational security planning
- RF spectrum analysis — across cellular, Wi-Fi, Bluetooth, Zigbee, LoRa, and licensed/unlicensed sub-GHz bands
- Non-Linear Junction Detection (NLJD) — locates semiconductor electronics regardless of power state
- Thermal imaging — identifies active electronics behind walls, ceilings, and furnishings
- Physical inspection — fixtures, fittings, network sockets, electrical outlets, smoke detectors, presentation equipment
- Telephony and network audit — VoIP infrastructure, conferencing systems, structured cabling integrity
- Acoustic leakage assessment — windows, partitions, HVAC ducting
- Reporting — written report with findings, photographic evidence, and remediation recommendations
Engagement Models
- One-off sweep — pre-meeting, post-incident, or post-construction validation
- Scheduled programme — quarterly or semi-annual sweeps for permanently sensitive environments
- Travel sweep — hotel suites, meeting rooms, and conference venues prior to a high-value engagement
- Vehicle and aircraft inspection — for executive transport
Operational Confidentiality
All TSCM engagements are delivered under strict confidentiality. Findings are reported to a single named recipient, evidence is retained for an agreed period and securely destroyed, and our consultants operate under non-disclosure agreements compatible with the most restrictive corporate and government information-classification regimes.
