In the German industry almost half of the companies works with an external IT service provider for security reasons. This is the result of a representative survey commissioned by the digital association Bitkom among 504 manufacturing companies. A quarter uses an external service for the entire IT security. In 56 percent of the company solely cares the IT department on the subject. Whether companies collaborate with external partners depends not on their size. 46 percent of small businesses with 10 to 99 employees, 49 percent of the average (100 to 499 employees) and 42 percent of large enterprises (500 and more employees) are working on the subject of security together with an IT-provider.
