TSCM
Technical Surveillance Counter-Measures — professional bug sweep services for government facilities, embassies, boardrooms, and high-value residences.
Sweeping for Threats You Cannot See
Hostile technical surveillance — concealed audio devices, cameras, network taps, and RF-emitting implants — operates in silence until it does not. Mission Support TSCM teams conduct systematic, methodology-driven sweeps of facilities, vehicles, and communication infrastructure to detect and remove technical threats before they compromise operations.
Our sweep teams are drawn from intelligence, counter-intelligence, and signals-intelligence backgrounds. Equipment covers the full detection spectrum: RF, acoustic, optical, network, and TEMPEST. Every engagement is documented and produces a classified-grade sweep report.
TSCM is a preventive discipline. The most effective posture is systematic and recurring — not reactive. Mission Support works with clients to establish sweep schedules calibrated to threat level, facility sensitivity, and operational tempo.
Detection Capabilities
- RF Spectrum Scanning — All bands including sub-GHz, GSM, Wi-Fi, Bluetooth
- Acoustic Device Detection — Wired and wireless, active and passive
- Optical / Camera Detection — Visible and infrared lenses
- GSM / IMSI Interception Device Detection
- Network Tap & Data-Exfiltration Device Inspection
- TEMPEST / Compromising Emanation Assessment
- Physical Facility Inspection — Cavities, furniture, infrastructure
- Post-Sweep Documentation & Classified Sweep Report
How TSCM Engagements Are Structured
Four standard TSCM engagement types. Most requirements map to one of these or a combination; threat level and facility sensitivity determine the protocol and recurrence.
Pre-Occupancy Sweep
- Scope
- Full technical sweep of a facility before first occupation or following a period of uncontrolled access — new premises, post-renovation, post-maintenance, or following a change in security posture.
- Best for
- New embassy premises, executive residences, conference facilities before a sensitive meeting, facilities following contractor access.
- Methodology
- Full-spectrum sweep: RF passive and active, acoustic, optical, TEMPEST, network, and physical inspection. Produces a baseline certification report. Recommended as the first engagement at any new facility.
Periodic / Scheduled Sweep
- Scope
- Recurring sweeps at intervals calibrated to threat level — quarterly, bi-annual, or annual. Detects newly placed devices since the previous sweep and tracks changes in the RF environment.
- Best for
- Embassies and diplomatic missions, governmental facilities, executive boardrooms, secure conference rooms in use for ongoing classified or commercially sensitive discussions.
- Methodology
- Full-spectrum sweep on each visit. Delta reporting against the previous baseline — new findings are flagged for immediate escalation. Recurring schedule is documented in the security management plan.
Event-Specific Sweep
- Scope
- Targeted sweep of a venue immediately before a sensitive event — board meeting, diplomatic negotiation, governmental summit, or high-value client meeting. Rapid turnaround; sweep team on site and cleared before participants arrive.
- Best for
- High-stakes negotiations, diplomatic conferences, board-level strategy sessions, governmental meetings where attendees include principals at specific risk.
- Methodology
- Compressed-timeline full-spectrum sweep of all rooms, corridors, and infrastructure in scope. Sweep team remains on standby during the event if required. Immediate report on completion.
Continuous Monitoring Programme
- Scope
- Persistent RF and acoustic monitoring infrastructure installed at a facility under continuous threat. Alerts on anomalous emissions in real time. Supplemented by periodic physical sweeps.
- Best for
- High-threat embassies, defence ministry facilities, intelligence-adjacent operations centres, executive residences under sustained targeting.
- Methodology
- Sensor array installed by a Mission Support TSCM team. Monitoring is continuous and automated; alerts escalate to the security operations centre. Physical sweeps conducted quarterly at minimum alongside the monitoring programme.
TSCM Team Pedigree
Mission Support TSCM operators are drawn from military signals intelligence, counter-intelligence, and electronic warfare backgrounds. All hold applicable security clearances and undergo documented vetting.
Equipment is professional-grade and maintained to current detection standards. RF receivers, non-linear junction detectors (NLJDs), time-domain reflectometers, thermal cameras, and spectrum analysers are all in the sweep kit.
Every engagement is conducted under strict operational security. Sweep schedules, findings, and reports are treated as classified documents. Mission Support does not retain client data beyond the contractual period.
Why Mission Support for TSCM?
Intelligence-Grade Methodology
Procedures derived from military counter-intelligence and signals-intelligence doctrine — not commercial IT security practice.
Full-Spectrum Detection
RF, acoustic, optical, network, TEMPEST, and physical inspection in a single engagement. No detection gap.
Classified Reporting
Every sweep produces a documented sweep report suitable for government, legal, and insurance purposes.
