Poolster Solutions
About us
Poolster is Dutch for the North Star: the fixed point in the sky sailors steered by for centuries. That is what we want to be for business owners.
Poolster Solutions is run by two former naval officers. Holding a course under pressure is what we are used to. We bring that discipline to IT: honest advice, technology we understand ourselves, and security that is there from the start.
What we stand for
Honest advice
If something isn't needed, we say so.
Security by design
Security is not an add-on; it is the starting point.
Your data, your choice
EU hosting or local: you decide where your data lives.
