Around 4.8 billion devices are expected to be connected to the Internet of Things (IoT) by the end of 2019. At least that’s what Gartner analysts estimated. This represents an increase of around 21.5 percent compared to the previous year. Unfortunately, many IoT solutions do not provide more security. Quite the contrary. According to a study by the security experts of “Unit 42” of the American company Palo Alto Networks, more than half of all connected IoT devices are vulnerable to attacks.
