Electromagnetic shielding for Emission Security (EMSEC or emanations security, and often broadly referred to as TEMPEST, a codename coined by the US governement)
is a growing
new field of application for high-frequency screening systems.
in architectural shielding against microwave and radio-frequency radiation
provides us with unrivalled experience in the installation of electromagnetic
shielding used for EMSEC applications, and the ability to provide
highly efficient and cost effective solutions to our clients regardless
of project size.
Industrial espionage, as well as wireless attacks from hackers and identity
thieves, can be prevented by the installation of an effective emissions
security shielding system. The installation is unobtrusive and visually
undetectable, providing an additional line of defence for sensitive and
commercially valuable information.

Electromagnetic shielding is an effective measure in blocking the radiofrequency emissions of listening devices, bugs or other wireless communications devices
installed illicitly in meeting rooms and offices,
also in avoiding the unauthorized use or interception of data transmitted by wifi or bluetooth, and denying the use of cellphones.
Our standard sheilding material is a metallized polyamide fleece with shielding effectiveness of 100 dB at a frequecy of 1 GHz, which can be installaled on
walls, floors and clielings and subsequently covered by standard materials like plasterboard and flooring laminates if requiured. Doors, windows and other
openings must be shielded - we carry a full range of materials, including shielded air vents, to form a complete electromagnetic enclosure.
Similar techniques are used to to protect wireless systems such as wifi against hacking. The first line of defence for your IT systems is
a correct configuration of your software security, including secure passwords and encryption, but sophisticated hackers could overcome these barriers
giving the attacker access to sensitive corporate information, email accounts, etc. Thus wifi signals emitted outside your premises represent a weak point
in your data security. EMSEC shielding avoids this situation. The shielding system should be designed bearing in mind the fact that cellphones used by
your employees can also be affected.
The interception of Van Eck emissions (sometimes known as Van Eck phreaking) is an espionage procedure that uses the detection of electromagnetic
emissions from computer monitors to reconstruct the content of the screen.
The information shown on a computer screen is transmitted to the monitor by high-frequency electrical signals, which also generate electromagnetic radiation.
This electromagnetic radiation can traverse walls and distances of tens of meters - and can in principal
be deconvoluted to reveal the content of the computer screen.
The effect was discovered in 1985 (by the Dutchman Van Eck) using cathode-ray (CRT) monitors, but more recent research by investigators at the
University of Cambridge has shown that flat screen LCD monitors, and laptop screens are also vulnerable to detection and decoding of Van Eck radiation.
In this case, the equipment used to decode the signals in the laboratory was relativly unsophisticated and cost less than $2000.
A suitably designed EMSEC system discreetly blocks the emission of Van Eck signals from your computer outside your offices.
