The GI (Groupement Informatique) is established in 1986 as an ICT entity shared by OMOB (presently Ethias) and three Liege utility companies: CILE, ALG and ALE, the latter two of which are currently part of the Nethys group.
The same four shareholders, joined by CCB (Crédit Communal de Belgique), Coditel and Electrabel, found the limited liability company NRB in 1987. Its aim is to reduce increasing ICT costs and use the competencies of the employees of the new company. This means that NRB initially only provides services to its own shareholders.
Created in 1989, the GIEI (Groupement d’Intérêt Economique et Informatique) entrusts NRB with the management of the ICT resources of the French Community of Belgium and the Walloon Region (presently the Walloon-Brussels Region). NRB modernises and secures its installations from 1995 onwards and expands them significantly in 1995.

Stesud, a company that specialises in solutions for the local public sector, joins the NRB Group in 2013. The company is acquired by Adinfo and subsequently merges with Adehis to become Civadis. At the same time, NRB fulfils its role as an economic engine by investing in the start up Afelio. Based in Liege, this company designs and develops mobile and web applications.
In 2014 and 2015, the NRB Group continues to grow by acquiring Ciges and Mims, two companies offering ICT solutions for the healthcare industry.
