In today's world, computers and the associated data processing are used in almost all areas of life. In business and industry, as well as in the service sector and crafts, computers are utilized for daily work. The goal of the IT system house Braasch & Jäschke Computertechnik (short: BJC) is to facilitate and simplify this work. BJC develops software for clients across Europe who operate in the fields of architecture, civil engineering, and facility management. To protect these proprietary software developments and thus the company's know-how from unauthorized duplication, the software must be safeguarded through appropriate measures.
