What is a TSCM Survey?

Technical Surveillance Countermeasures (TSCM) is the industry term for security work that includes debugging sweeps, wiretap detection, and related counter surveillance activities. The purpose of TSCM is to help businesses and individuals protect themselves from unauthorized and illegal spying activities. TSCM involves the systematic physical and electronic examination of a designated area by properly trained, qualified, and equipped persons in an attempt to discover electronic eavesdropping devices, security hazards, and/or security weaknesses.

A Technical Surveillance Countermeasures survey is a complicated procedure requiring both investigative and technical skills. TSCM training is obtained from government and private sources, and must be a continuous process. A proper survey will utilize laboratory grade test equipment and equipment specifically engineered for TSCM work. The equipment seen listed in most “spy shop” catalogs does not fall into either of the preceding categories. The purpose of the TSCM survey is to locate any electronic intelligence gathering devices, and to identify any naturally occurring audio paths which could be exploited for espionage purposes. The survey will also identify procedural deficiencies which detract from the overall security of the facility or residence.
