In 2005 the portfolio of services was significantly expanded. The continuous demand of clients to ensure not only the supply of computer technology and outsourcing of services, but also a high-quality Internet connection, led to the purchase of the local Internet network Nextnet and the final renaming of the company to CS21 Nextnet, s.r.o. The company thus acquired the necessary know-how and over the next 3 years its client base expanded by more than ten times. At the same time the company gained the trust of the multinational company IBM and became its contractor for selected technical activities.
