Add Cloud Services, Remote Updates and New Capabilities to Existing Equipment

  • Guardian adds secured internet connectivity to equipment already in service, by utilizing existing Ethernet or USB ports of the unconnected device.
  • Microsoft's Azure Sphere Security Service ensures comprehensive certificate-based authentication, failure reporting, plus over-the-air software updates
  • This OTA software update capability is provided for the life of the product and covers Azure Sphere OS and Guardian application firmware, plus firmware updates to the end-equipment
    (ie. a managed service to securely push software updates to downstream previously unconnected devices, eliminating costly service calls to update that field equipment)


Here's an example use of Guardian 100, interfacing existing coffee-making equipment to Azure Sphere Security Server and Cloud Services
