Company history

Employing over 1,400 workers, the NSI Group is a subsidiary of Cegeka and Noshaq and a 25.02% shareholder. From a geographic point of view, the group covers all of French-speaking Belgium and also works in Luxembourg, where it recently expanded its business and its workforce.

Acknowledged as one of the main IT service players in the Wallonia-Brussels area, NSI owes its success to its teams, and it is fully aware of this, making its strategy revolve around them; what’s more, it is the ‘human’ and ‘outreach’ factors that truly define the company’s DNA.

A mindset that has always been hard-wired into NSI. To be in close cooperation means working alongside your customer, helping them with advice and action.

Close cooperation sums up the common thread running through our growth history. It is the combination of our values. It is how we have grown with our customers and vice versa, on the basis of trust built up over the years.
