Safe Room Service

We provide a Safe Room Service, where a TSCM Investigator will come in just prior to your meeting, set up our equipment, both Spectrum Analyzers and Acoustic Noise Generators, conduct a preliminary bug sweep and stay to ensure no information is leaked or broadcasted.

Continuing security and maintenance of your security position requires re-sweeping a location on unannounced regular intervals. Our process marks previously cleared outlets and electrical equipment which dramatically reduces the cost of follow up visits.
