Also called ‘debugging’ or ‘sweeps’, Electronic Security Technical Security Counter-Measures (TSCM) refers to the procedure for locating covert surveillance devices in your office, home, on phone lines, etc. Minerva is an industry leader in electronic counter surveillance. Following an electronic sweep, Minerva will provide a detailed report outlining the specific technical measures used during the sweep, along with the specific findings of the investigators. And with the results of each search, we also provide recommendations for follow-up or corrective action to be taken by the client to secure its facility against further or other electronic intrusions. If the sweep indicates an electronic penetration, we can conduct an investigation to determine the source of the monitoring, and to preserve and present evidence for criminal prosecution and/or civil litigation against those responsible.
