Publications

Tesorion has a clear vision, we want to be relevant and contribute to a cyber-safe Netherlands. In addition, our experts visit our customers daily (in many cases virtually). During our activities and investigations we encounter new threats or the solution against them. It is precisely this knowledge that helps to improve cyber security, minimize and solve cybersecurity challenges. In short, we bundle all that information into different types of publications. We are happy to offer you these via this page.
