Frequently asked questions about Azure Sphere

  • Azure Sphere components are tightly integrated and sold together at a single, one-time cost—delivering a highly secure solution for building connected devices and scaling your IoT deployment.
  • Azure Sphere works with a diverse group of expert hardware manufacturers and their broad ecosystem of vendors to design specialized Azure Sphere–certified chips that meet the needs of various markets. Extensive research and testing contribute to the development of the security technology and architecture for each Azure Sphere–certified chip.
  • Azure Sphere does not require you to pay any ongoing fees. The one-time cost you pay for your MCU chip includes access to the Azure Sphere OS, Azure Sphere Security Service, and OS updates for the lifetime of your chip.
  • If you already have connection-capable devices and equipment deployed within your organization, or if you’re considering connecting devices for the first time, Azure Sphere can help you protect your devices with guardian modules.

    Guardian modules are physical attachments that require little or no equipment redesign, processing data and controlling equipment without ever exposing the equipment to the network. Guardian modules protect your operational equipment from disabling attacks, simplify device retrofit projects, and boost efficiency through over-the-air (OTA) updates and IoT connectivity.

  • Azure Sphere is engineered to integrate with any cloud service, public or private—not just Azure. You can connect to other clouds for app data while running Azure Sphere—or optimize efficiencies by using Azure Sphere alongside Visual Studio and Azure IoT.
  • Azure Sphere provides a complement to Windows for IoT. Windows IoT provides a best-in-class solution for devices with MPU-class processing power or rich user experiences. Azure Sphere brings Microsoft security innovations and expertise in hardware, software, and the cloud to IoT devices.
