My IT system house partner for many years. Always friendly, always fast, with know-how that is always up-to-date. As a network partner I can't imagine life without them - as IT system house professionals as well!
I can highly recommend André Schiller for digital transformation, Microsoft 365, cloud and as an expert for hybrid system environments. He is reliable and a master of his trade. My absolute recommendation!
We experience coretress as a reliable service provider that thoroughly understands the meaning of the words "service" and "perform". Communication takes place at eye level and response times are always adapted to the circumstances. In urgent cases, someone is always there at short notice, which is important to us. We look forward to further cooperation.
For eleven years (incl. company start-up and several moves) we are absolutely satisfied. Fast and targeted help, despite 400 KM distance. Great suggestions to increase safety and productivity over time.
We are very, very grateful to "coretress GmbH" for your quick and very professional help!
Unfortunately, we previously had to make very bad experiences with an online information systems GmbH in Oberberg. Due to an unprofessional, professionally incompetent and humanly empathetic approach after a hack attack, they were not only unable to help us at all for several weeks, but also caused us great damage both financially and emotionally due to blatant errors.
The experts from "coretress", on the other hand, had an immediate solution at hand due to their outstanding, professional competence. They immediately freed us from the evil and additionally helped us to a secure system for the future.
The professional competence impressed and inspired us, the very personal and visionary advice made us look into the future with more confidence again, but above all the very high level of empathy and understanding quickly took away our despair and gave us back a good feeling.
We are very satisfied with the team around Andre' Schiller
Highly professional - a lot of know-how and very good empathy our individual situation
Very good service - fast, flexible and competent
Sympathetic - helpful and friendly even after the 10 queries ;)
