Feedback from our customers

Experience teaches, your advice is always very valuable to us
I turned to National Services for an event organized by the publishing company for which I work in the premises of a Roman university. I relied on the history of the company and on the convincing words of those who explained to me the services that would have been offered to me. The attention to detail has done the rest. I am fully satisfied and will be back to use National Services

I chose National Services doing research on the company's reputation in Italy. I am an Argentine entrepreneur and could not rely on chance. I had to protect the premises that keep the servers for the cloud computing offer of my IT company. Never a problem, never any case of intrusion. The reports are fantastic. Pre-sales communication is precise and not at all aggressive.

I asked NSG for advice to know the risks of leaving some of our offices detached from the central office. Quote obtained very quickly with suggestions to optimize the cost / benefit ratio in my specific case. Company well known in the sector. The results obtained and the feedback from other customers help us understand that we are on the safe side.
