Every day there are cyber attacks in the industrial sector − only the most spectacular incidents make the headlines. Like the attack on the automotive supplier Continental last summer or on the commercial vehicle supplier SAF-Holland in March this year. The financial damage caused by such attacks and the loss of trust among customers and employees are enormous. As protection against cyber attacks, the Federal Office for Information Security (BSI) now recommends that companies use a browser with so-called virtualised instances for the first time. This is because most attacks enter company networks via the internet. Such a browser can systematically keep attackers out of the network and is therefore a particularly effective protection.
