GDIS - Cyber Shield

The proliferation of computing and telecommunication has made our lives much more comfortable. At the same time, it is much easier for criminals and rivals to spy on you. GDIS is constantly monitoring and mapping the cyber-security risks.

Clear Rooms

Whether you are gathering for a formal or informal meeting, your rivals are on guard. Using modern miniature devices, they can place microphones, bugs, spy-cams and monitor electronic, electromagnetic and voice without even accessing the perimeter.


GDIS solutions are ideal for board and executive rooms dealing with classified information.

The system eliminates the eavesdropping risks by:

  • Bug Sweep: from electronics- voice, audio, electromagnetic, recorders and transmitters.

  • Activation of noise blocker.

  • Elimination of any transmission signal from the Room.

It is highly recommended to professionally scan meeting rooms and surroundings periodically and upon replacement of executives or visits of guests and technicians.


The same services are also applicable for hotel rooms, lounges, conference centers, residencies, planes and yachts.

Usage of cellular communication is part of our daily life. Practically all of our assets are in a phone or reachable by the device. This concentration of information is facing major risks, such as:

  • Attacking

  • Eavesdropping

  • Manipulation

  • Hostile takeover

Home and Family

Just like the office, your residencies must be secured to protect your family members, valuables, assets, documentation and data stored in your home devices.

Hackers may try to identify breeches in your security via the family, smart-home appliances and service personnel that are less aware of the needed level of security.

In effect, you must order a periodical proper sweeping of the house and vicinity, identify and certify any signal, and provide family/staff with secured tools, passwords and training.
