About us

HEINEN Elektronik is a medium-sized family business located in Haan, NRW. We have been developing and manufacturing customized electronics since 1969. Our wide range of services extends from electronic modules to complex system solutions. On request, we offer all electronic systems as ruggedized hardware with robust housing.
In 2015, we expanded our competencies by acquiring the system house ICOS. This resulted in the business unit HEINEN ICS (Individual Computer Security), which specializes in the development and manufacturing of hardware-based IT security systems.
The motivation to build up the business unit Individual Computer Security results from the partly desolate security situation at security-critical computer workstations. In view of the acute danger of hardware-based cyber attacks, IT security officers in public authorities and state institutions should review the measures taken. It is important that the security of processed personal and sensitive data, especially in critical infrastructures (CRITIS), includes appropriate security of the IT hardware.
Our patented NoSpy-Box® prevents uncontrolled leakage of sensitive data into the power grid and thus prevents data theft without a trace. It is a further development of the proven filter boxes from the ICOS FB-2 and ICOS FB-3 series, which are listed by the BSI under the designation "filter boxes" and have been part of the security standard of the German Federal Armed Forces for many years. The NoSpy-Box® guarantees user-friendly computer work at the highest security level.
Based on commercially available computer hardware, HEINEN ICS also develops components that guarantee the highest level of hardware security for computer workstations.
