An IoT gateway is a device or software program that bridges the cloud to controllers, sensors, and smart devices. All the data that moves to the cloud has to pass through the IoT gateway. While a sensor produces multiple thousands of data points at a time, the IoT gateway gives an edge to mine the data before it reaches the cloud.
IoT gateways also help protect data flowing in both directions from malware attacks like tamper detection, encryption, and crypto engines. We build IoT gateways that are capable of all these strengths along with the ability to minimize the volume of data that reaches the cloud. We also build sensors that talk to the IoT gateways that, in turn, communicate with the cloud.
