How Safe is Your Digital World From Eavesdroppers?

Take a moment right now, and ask yourself these series of questions:

1. Do you know the first names of your outside cleaning staff? How about even the name of the company?


2.  Do you have a key card access system in your company? If you do, who monitors the program?


3. Do you screen visitors and contractors?


4. Do you have your meetings in a unsecured conference room?


5. Do you have a security alarm service or CCTV cameras?


6. Are your comments and plans being picked up by other parties? 


If you answer no, to any of these questions, you company is susceptible to eavesdropping devices.

Bug Sweep Equipment

Many of our clients schedule electronic sweep services on a periodic basis to ensure a higher level of protection. Client relationships are maintained on a confidential basis and sensitive information is handled discreetly. 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.  Eavesdropping Countermeasures are usually conducted for the following reasons:


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.
