Technical Surveillance Counter Measures (TSCM)

Technical Surveillance Counter Measures

Modern surveillance technology is increasingly accessible and difficult to detect without specialist equipment. Our TSCM service provides comprehensive sweeps of premises, vehicles, and communications infrastructure to detect any form of covert electronic surveillance or eavesdropping device.

Our practitioners use the most advanced detection equipment available, carrying out sweeps to the highest professional standards. We detect RF transmitters, hardwired devices, carrier current devices, optical surveillance equipment, and compromised IT infrastructure.

When Should You Commission a TSCM Sweep?

A TSCM sweep should be considered whenever sensitive information may be at risk. We recommend regular preventive sweeps for any environment where commercially sensitive conversations take place — the cost is invariably far less than a single compromised negotiation.

• Corporate boardrooms & executive offices
• Private residences & primary homes
• Legal & financial services firms
• Sensitive negotiation or arbitration venues
• Government offices & diplomatic premises
• Vehicles used by high-profile principals
• Hotel suites during sensitive engagements
• Any environment where sensitive data is discussed

Sweep Protocol & Reporting

Every TSCM engagement follows a rigorous documented protocol — we conduct a prior threat assessment, carry out the sweep in complete privacy, and on completion provide a detailed written report covering findings, vulnerabilities, and recommendations.

We also provide advice on secure communications protocols, network security hardening, and physical security measures to prevent future compromise of your environment.
