    Avnet Guardian 100 is a wireless edge module that uses Azure Sphere to deliver secure connectivity to devices, helping businesses get the most out of their existing equipment investments. Guardian 100 includes Avnet's Azure Sphere MT3620 module and securely connects to existing equipment via Ethernet or USB providing a secure connection to the internet via dual band Wi-Fi. The Azure Sphere device in Guardian, communicates with the cloud, not the device, therefore, protecting equipment from attack, ensuring data is only transmitted between trusted cloud and device communications partners, and ensuring the software of the module and the equipment remains intact and secured. Avnet Guardian-enabled devices also receive automatic security updates through the Azure Sphere Security Service. With Avnet Guardian, enterprise customers can more confidently connect existing devices to the cloud, helping them to operate more efficiently, drive innovation, and create a better customer experience.

    Beyond retrofitting existing devices, Avnet Guardian can also be used in scenarios where current connectivity does not meet enterprise-level security requirements. Avnet Guardian is a good fit for any industry that operates using mission-critical, capital-intense equipment.

    Businesses can start seeing value right away with plug and play modules that are easy for anyone, including non-technical onsite employees, to install. Avnet Guardian also integrates with Avnet's IoTConnect, a secure, cloud-based platform and a portfolio of pre-built, smart, industry-specific connectivity solutions that businesses can use to quickly implement innovative IoT solutions and gain real-time data insights.

    Avnet Guardian includes Azure Sphere. Customers will need an Azure tenant, which is free, to enable the automated Azure Sphere security updates. Azure Sphere can be used with other, non-Azure cloud services or even pushed to a customer's existing, internal data center.
