Years of Experience

„GISA stands for highly trained, committed employees who work in partnership as equals. Our quality standards and our pronounced passion for IT spur us on to constantly develop ourselves further. Proof of our success are our trusting customer relationships with renowned companies and institutions, some of which have lasted for decades. We are proud of that!”

Michael Krüger, GISA Managing Director

Our Responsibility

Commitment is important to us!

We at GISA are aware of our social, economic, and ecological responsibility as a national company with strong regional roots and are committed to a wide range of areas. Sport is our special focus. We are a dynamic sporting brand: sports are fun, connect people, and are important for the health and thus for the performance of our employees. This is why, in addition to in-house sports groups and initiatives, we also promote sports in the region – as a sponsor of the Bundesliga women’s basketball team GISA LIONS and the Bundesliga triathlon team GISA runIT.


As an innovative and forward-looking company, we also pay great attention to projects that focus on innovation and intelligent, forward-looking ideas. For example, we have been a passionate  partner and sponsor of the IQ Innovationspreises Mitteldeutschland. GISA also supports  SummerBYTE, a summer school run by the Institute for Computer Science at the Martin Luther University Halle-Wittenberg for the sustainable recruitment of specialists for the IT industry..


But GISA does not only have its fingers in lots of pies as a company, our employees also invest a large part of their free time into various associations and projects in order to make a contribution to society. This valuable commitment demonstrates our responsibility in kindergartens or projects for children’s homes and family centers at our locations.

Our Environmental Policy

Economic activity and innovative design are often associated with interventions in nature. As part of the overall global ecological system, we see our daily activities as a contribution to maintaining the ecological balance and preserving biodiversity in this system. As a commercial enterprise, we acknowledge our special responsibility and want to fulfil our contribution to the preservation of our natural environment.


That’s why GISA has introduced an efficient environmental management system in accordance with the international standard DIN EN ISO 14001. This system results in continuous improvements in environmental performance and environmental protection. We monitor compliance with effectiveness through regular audits.


We already take environmental protection requirements into account during the development and testing phase for new products and services. We endeavor to use the best available technology as early as the planning stage and during the installation and operation of our technical systems. We also make use of every opportunity to save energy and raw materials,  as well as avoid, reduce, or recycle pollutants, noise emissions, and waste.


Every employee at our company is required to make an active contribution to environmental protection. We use  information and training to encourage our employees to act in an environmentally conscious manner. All workstations are geared towards the preventive protection of the health and safety of our employees. Our employees are continuously reminded of their personal responsibility in carrying out their activities in a safety-oriented manner. We create incentives for innovation and improvement through an attractive and motivating “Company Idea Management”.
