Have you been exposed to serious IT security incidents?
In order to provide the best possible service in terms of preventing, resisting, and handling cyber attacks, it is essential that the Centre's Network Security Service holds the necessary data to create the best possible overview of the current situation regarding the Danish Internet infrastructure.
Consequently, public authorities are obligated to report serious IT security incidents to CFCS, and private companies are also encouraged to report serious cyber incidents to the Centre.
