An Internet of Things gateway may be a physical device or a software application. Its purpose is to permit connections between Internet of Things devices and the network that transmits data from the devices to a centralised platform, such as the public cloud, where the data is processed and stored. Smart device gateways and cloud endpoint protection products have the ability to move data in both directions while also assisting in the prevention of data from being compromised.   These products frequently employ strategies such as tamper detection, encryption, crypto engines, or hardware random number generators. Gateways may also incorporate characteristics that assist Internet of Things communications, such as caching, buffering, filtering, data purification, or even data aggregation. These features might be included in a gateway.
