The Centre for Cyber Security was set up in December 2012 within the Danish Defence Intelligence Service (DDIS). As a part of the DDIS, the Centre has access to the special intelligence-based knowledge about cyber issues available to the DDIS while the attachment also creates a number of synergies. The Centre for Cyber Security is the national IT security authority, Network Security Service and National Centre for Excellence within cyber security. The Centre’s mission is to advise Danish public authorities and private companies that support functions vital to society on how to prevent, counter and protect against cyberattacks.
