Azure Sphere

Create, connect, and maintain secured intelligent IoT devices from the edge to the cloud.

Create, connect, and secure IoT edge devices

Azure Sphere is a secured IoT platform for building solutions that start in silicon and extend through the OS and the cloud. Securely connect, manage, and protect new and existing intelligent devices.

Diverse catalog of devices provides options to securely connect existing devices or build new highly secured intelligent devices

Over-the-air update functionality and powerful development tools make it easy to deliver improvements and patches to any device

Security improvements developed and deployed by Microsoft help protect against emerging threats across the device lifecycle

Interoperation with IoT platform services like Azure IoT Hub and IoT Central simplifies deployment, creating business value faster

Help secure intelligent devices from chip to cloud

Protect your device, data, and infrastructure on all fronts—hardware, software, and in the cloud. Trust that your data estate is secured with an end-to-end IoT security solution to connect existing equipment and create new IoT devices. Connect your existing devices to the cloud with Azure Sphere certified guardian modules or get started embedding Azure Sphere into new devices with the development kit.

Frequently asked questions about Azure Sphere

  • No. Azure Sphere components are tightly integrated to help ensure a secure and simplified device. They are sold together for a one-time cost and cannot be purchased separately.

  • No. Microsoft 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 chip.

  • No, Azure Sphere doesn't require you to pay ongoing fees. The one-time cost you pay for your chip includes access to the Azure Sphere OS and cloud-based security service, plus OS updates for the lifetime of your chip.

  • Yes, Azure Sphere guardian devices can help you protect the connection-capable devices and equipment already deployed within your organization. Guardian modules require little or no equipment redesign. They process data and control 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.

  • No. Azure Sphere is engineered to integrate with any cloud service—public or private. 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 complements Windows IoT. Windows IoT provides a best-in-class solution for devices with rich user experiences. Azure Sphere fortifies IoT devices with Microsoft security innovations and expertise in hardware, software, and the cloud.

  • Azure Sphere supports coordinated vulnerability disclosure and encourages responsible reporting to Microsoft by security researchers and customers. If you believe you have discovered a security-related vulnerability with Azure Sphere or have been affected by one, please contact us. Include clear, concise, and reproducible steps, documented either in writing or video format, to help the security response team quickly reproduce, understand, and address the issue.
