They are the same function under two names. The Chief Information Security Officer, known in Germany as the Informationssicherheitsbeauftragter or ISB, is the named person who coordinates the information security process, assesses risk, and advises management. An external CISO, also called CISO as a Service or a vCISO, holds that function as a service. With Kertos, you formally appoint a certified specialist from our team to the role.
