Technical Surveillance Countermeasures

A Technical Surveillance Counter Measure (TSCM) sweep utilizing our proprietary SignalTec™ service can provide your organization with the peace of mind that comes with knowing that your facility is secure. Commonly referred to as a bug sweep, these searches can identify and eliminate covert listening/recording/tracking devices from your office, home, or vehicle. 

State-of-the-art technology utilized by trained and certified operators, SignalTec™ can locate even the smallest and most complex devices. Some of the equipment we use includes:
