The Club of Information and Digital Security Experts – The Club des Experts de la Sécurité de l'Information et du Numérique (CESIN) in French - is a 1901 law association promoting the exchange of knowledge, the sharing of experience and cooperation between professionals in the field of information and digital security.
Their active members are experts in information and digital security management positions (CSO, DSSI, CIO, CISO), within private or public companies, excluding commercial companies whose main activity is the supply of information and digital security equipment or advice.
Law Specialists, associated with information and digital security, are also active members. Associate members are representatives of State services (justice, police, Prime Minister's services) whose activity is carried out in close collaboration with information and digital security experts, members of CESIN.
