Over the past few years, the Internet of Things (IoT) has captured headlines across the world. With its network of “Smart,” sensor-enabled devices that can communicate and coordinate with one another via the Internet, the IoT can facilitate computer-mediated strategies for managing city resources, energy management, and numerous other tasks. However, the way forward for IoT may be complicated. As with any technology in its early stages, cybersecurity concerns will be prevalent. There have already been instances of hackers wreaking havoc by infiltrating connected IoT devices.

In light of the essential need for security, EtherWAN’s AiR GUARD is an advanced IIoT cellular gateway and 4G LTE PoE device specifically optimized for secure IoT data transmission, running with Microsoft’s Azure Sphere. Offering not only secure connectivity, it also provides industrial protocols and easy to use data pre-processing and conversion for efficient and low-cost edge to cloud connectivity. AiR GUARD is your IoT guardian.
