History of our company


The history of our company dates back to the early 1980s. Elisabeth Norz, at that time a young telecommunications engineer, worked in an office-partnership with one of these early IT companies. They had more than enough work, Elisabeth’s company not, so she switched over and develloped software.

In 1989, Elisabeth officially founded her own business. It had been a one-woman show, until, two years later, Johannes joined. Together, they developed a payroll application for health-care business in Clipper and C/C++.

Johannes had been working in the development of medical ultrasonic appliances for Kretz-Technik (today: GE-Medical) and had a strong UNIX and networking background. So over time, the business changed to computer networking. First certifications had been about Windows, but soon Citrix came into the picture: Metaframe 3.5 for NT 3.51, Metaframe 4 for NT 4. Elisabeth got Certified LPI, a leading certification for Linux.

Johannes started teaching in 1997. First themes had been TCP/IP and Windows Terminal Server. For a short time, Johannes had been MCSE for Windows 2000 and 2003 as well as MCT. In 2002, Johannes got certified CCA, Citrix Certified Associate and CCI, Citrix Certified Instructor (he still renews this certification on a yearly base), main focus: CSG, Citrix Secure Gateway.

Elisabeth backtracked from daily business. She does all the paperwork, accounting and legal stuff. Besides, she studied science in sports and works as a trainer.

But Johannes always preferred UNIX over Windows, and when Linux came up, he refocussed to Linux. Due to lack of interest, Windows Certification expired. More and more, he became a one-trick pony, specialized in Citrix Networking, mainly Citrix ADC (formerly called NetScaler). CCE (Citrix Certified Expert on Application Delivery and Security) is his most important certification. Besides this, he constantly learns about security, vulnerabilities and protection of applications.

Beginning in 2018, he started working as a contractor for Citrix Consulting Services. The main focus here is Citrix ADC WAF, the web application firewall. Working for Citrix Consulting Services brings great projects and challenging problems.

Johannes is a very open-minded and communicative guy, so he likes teaching. So teaching and consulting still go hand in hand, profiting from each other: A strong theoretical background and plenty of practical experience make him an outstanding expert. In 2020, Citrix honoured him as a member of the elite circle of Citrix Technology Advocates (CTA).
