Market Restraint

Growing Issues Related to Security and Privacy of Data and Connectivity of Devices and Interoperability

When more devices, like IoT, are introduced to a network, the surface area grows, which could mean an increase in the number of attack vectors. It only takes one unsecured, actively attacking device to bring down an entire network. IoTs are being used in an increasing number of private network and device intrusions. The recent cybersecurity issue with Xiaomi Mijia intelligent security cameras prompted Google to stop supporting its devices. For example, a user who owned Xiaomi Mijia cameras connected to a Google Nest Hub received random images from other people's homes when streaming content from the camera to a Google Nest Hub. Such attacks on vital infrastructure in industrial space can cause enormous damage. One of the biggest pure-play semiconductor businesses (WannaCry) had to shut down some of its fabs due to ransomware spreading through the production network. Aside from industry, the infrastructure might be destroyed by an attack on smart city solutions like electricity grids, water systems, and communication networks.

Market Opportunity
