About EMshield GmbH
EMshield GmbH specialises in consulting, planning, project engineering and implementation of solutions in the field of electromagnetic shielding for special requirements. Its range of services includes eavesdropping- and emission-proof rooms (TEMPEST), technical shielding, high-security zones and the protection of critical infrastructures. For shielding, copper or sheet steel modules are used for shielded cabins, as well as the patented architectural room shielding system ARCtec®-flex with shielding attenuation of up to 80 dB in the frequency range 30 MHz to 6.0 GHz. In addition, the company offers active eavesdropping protection, construction-accompanying security measures, the distribution of counter-surveillance measuring devices and training courses. The owner-managed company employs architects, RF engineers and master craftsmen and implements projects worldwide with security-vetted personnel. The company is headquartered in Grasbrunn near Munich with office and training rooms, warehouse and shipping; production takes place in the immediate vicinity of the headquarters. Customers come from government agencies, the military, critical infrastructures and companies with high security requirements. According to its own statements, more than 2,000 eavesdropping-protected rooms have been installed.
