Electronic Eavesdropping Countermeasures (De-Bugging) can be defined as a combination of searches, both electronic and physical, which are intended to provide a business, person or organization some reasonable assurance of privacy against electronic surveillance devices (Bugs). The search or "Sweep" is conducted by utilizing sophisticated equipment and techniques, in conjunction with a meticulous physical inspection.

  • Expectation that confidential business or personal conversations are being intercepted, or a threat thereof.
  • Indication of a listening device
  • Noise on the telephone lines
  • Unsolicited telephone repair visits
  • Frequent leak of information
  • Telltale signs left by intruders
  • Domestic or business problems
  • Recent burglary with nothing taken
  • Labor negotiations or strike
  • Involvement in civil litigation / lawsuit. 

What To Do If You Suspect Eavesdropping:

  • Do not discuss your suspicions with others unless they have a need to know
  • Do not discuss suspicions in suspected area
  • Do not attempt to address your suspicions alone
  • Do not waste money on "Spy Toys"
