Collaboration is central to our projects. What sets this apart from our consultancy is that here we work from a project-based approach. We agree a start and end date, along with the responsibilities and the scope of the deliverables. And we always deliver finished projects that fit your vision and goals.

Managed Services

Sometimes, as an IT company, you get asked a question so often that you simply have to do something about it. That was certainly the case at USN. Customers asked us if they could simply outsource their Linux environment – and often the rest of their IT management – entirely to us.

Since then, we have managed the IT environments of a growing number of clients in the Netherlands and abroad from our office in Maarssen. We do this on their infrastructure or on ours. From five servers to five thousand, we are ready for it.

Client case in focus.

Major European player in the aerospace industry: replacing the SAP environment

For more than 25 years, USN has carried out Linux management and support work for this client. Over that period, our engineers have helped them with the daily management of their IT environment at their site in the Netherlands. That work ranges from application management through to building complex compute clusters. As well as supplying engineers, USN works with this client on a project basis, and over the years we have delivered many projects to their satisfaction.
