The rise of the Internet of Things (IoT) has driven mobile applications development. As a result, in the consumer IoT (CIoT) space, any product usually comes with a smartphone application to either control, programme, or just view what is happening with the product. The IoT brings with it opportunities and challenges to consumers. For example, IoT technology makes it possible to connect all of a person’s devices to create a smart eco-system or assemblage. However, the biggest threat in CIoT is personal data security. This study utilized a qualitative narrative inquiry and Delphi technique to explore data security issues that come with CIoT assemblages and associated mobile applications in South Africa. The study established that consumers enjoy the convenience and benefits that IoT technology brings. It is concluded that for CIoT to thrive, safety is crucial, and all the stakeholders in the IoT assemblage need to ensure the protection of consumers.
