Our Philosophy



A role model for the future

By supporting education, university thesis, student jobs, Girls Days and student internships, we support the next generation. Through Green IT, we also contribute to environmental friendliness: EFiS protects resources, saves energy and reduces pollutant emissions by using our own solar systems.

Customer orientation

Through close cooperation with our customers, individual requirements lead to constant technological progress. The challenges our customers have to face are our benchmark. We proactively solve our customers’ requirements in a permanent dialogue. Thanks to our locations, we are able to speak the language of our customers and partners not only professionally but also culturally.

Strong partners

We maintain long-term relationships with our partners to ensure effective cooperation. For example, our computer center is based on the powerful machines of our cooperation partner IBM.


The person counts

We stand for social commitment. That is why child days for mothers and fathers (or part-time for parents) and support for “Project 50plus” are a matter of course for us. We would like to preserve our experienced employees and the know-how of the last 40 years. Furthermore, we have been supporting the Janusz-Korczak-School in Langen for years and the missionary organisation „Stückchen Himmel“.

Active participation

We are actively involved in associations such as IHK, VDT, GSU, TWIST and the Economic Council in order to help shape new ideas. We also participate in the forums SWIFT (SIBOS), EBA, IBC, IFF and GSE: proactive – innovative – competent.

Inexpensive – but not cheap!

Our focus is on cost and benefit efficiency. For this reason, the use of state-of-the-art technology to improve our business processes is a matter of course for us.






Green IT

The digital revolution and the associated increase in energy demand require the intelligent use of modern information and communication technologies. At this point, Green IT is the key to greater efficiency, sustainability and the exploitation of existing energy potential.

By means of a solar system on the roof of the building, EFiS uses the generated energy to support the power supply of the data center. As a rule, a large part of the power consumption is used to cool and ventilate the hardware. Many data centers are still cooled down to around 22 degrees Celsius, although modern technologies permit significantly higher temperatures. The mainframes used by IBM z Systems have been operated at a temperature of 30 degrees Celsius for years.
