More than an IT service provider
For 17 years, our passionate IT professionals have been helping clients work faster, more securely and more innovatively. Personal and committed.

Information technology, security and ease of use have to fit together. That is what NSO stands for. Since 2009, NSO Schiedam has been supporting small and medium-sized businesses throughout the Rotterdam region with IT that simply works, so they can focus on their own business.
Our strength lies in our people. Keeping their knowledge up to date and always wanting to bring out the best in themselves is what our professionals do every day. We see that as the foundation for a service you can rely on.
We deliberately work with technology partners who share the same ambition: helping organisations work more securely, smarter and in a future-proof way. That is why we are a Microsoft Solutions Partner for AI Business Solutions and a KPN partner for business telephony. For hardware, we have standardised on HP for the workplace and Ubiquiti UniFi for the network, so we know the equipment inside out.
“The best company to work for: that’s who we are.”

How we work together
Choosing a new IT partner is a big step. That is why we follow a fixed, calm approach: from a first introduction to an environment that runs smoothly and keeps improving.
You know in advance what will happen, who your contact is and what it costs. We take over your environment in consultation with your current supplier, so work simply carries on. First we make sure everything is calm and stable, then we bring your IT up to standard step by step.
