​​​Counterintelligence Division

Among the most complex and sensitive assignments that Premier Investigation Group undertakes are those which involve protecting assets and personnel from exploitation via the use of wire tap detection and eavesdropping detection.  Espionage and illicit collection activities represent attempts by foreign governments, employees, and corporate competitors to acquire confidential, non-public proprietary information. The threat is so acute that the Director of the Central Intelligence Agency has warned corporate America to be alert to the threat and to take the necessary countermeasures to thwart the threat.

One of the most insidious threats to an unsuspecting corporate entity is the illegal interception and monitoring of audio and data communication. There has been increasing use of electronic eavesdropping devices. These devices can exploit the radio frequency generated by personal computers, cellular telephones, land line telephones, cordless telephones, and fax systems. The available technology for communication and data acquisition is immense. There is no such thing as safe communication without high speed encryption systems, but even with that technology there are vulnerabilities.  Our phoenix private investigators are specialists in wire tap detection and eavesdropping detection.

                                                                                             Premier Investigation Group offers wire tap detection and eavesdropping detection services

                                                                                             that utilize DOD level countermeasures equipment. We are also able to identify clandestine 

                                                                                             surveillance devices transmitting from DC to 71 GHz.  Thus, we can identify all friendly and not

                                                                                             Spectrum, Burst, Pulse Devices,and Sub-Carrier.
