The Federal Office for Information Security (BSI) was founded in 1991 and is a subordinate authority of the Federal Ministry of the Interior. As a national IT security agency, the goal of the BSI is to promote IT security in Germany. The BSI is first and foremost the central IT security service provider for the federal government in Germany. However, it also offers services to IT manufacturers as well as private and commercial users and providers of information technology because effective security is only possible when everyone involved contributes. The BSI analyses security risks and develops protective measures; it also provides information about the risks of using information technology and offers solutions. The BSI investigates security risks associated with the use of IT and develops preventive security measures. To minimise or avoid these risks, the BSI's services are intended for a variety of target groups.
