What Our Customers Say

The help we got from Truesec was utterly fantastic.

Jesper Särnholm

Head of IT, Addtech

It’s not a matter of if an attack will happen, as much as when it will happen. And when it does, it is such an intense situation. Especially when it is an attack of such a large scale as it was for us; it really brings another dimension to things.
