Azure Sphere

A solution for creating highly secured, connected MCU-powered devices to help you reimagine your business, drive innovation and delight customers.

Get ready for the MCU IoT revolution

Azure Sphere is a solution for creating highly secured, connected Microcontroller (MCU) devices, providing you with the confidence and the power to reimagine your business and create the future.

Find peace of mind

Security is foundational to connected IoT experiences. Don’t trust your brand to single line-of-defence and second-best solutions. The Azure Sphere approach to security is based on years of Microsoft experience and research. Together, Azure Sphere promotes security with crossover MCUs, our secured OS and turnkey cloud security service, guarding every Azure Sphere device and delivering end-to-end IoT security that responds to emerging threats – so you don’t have to.

Get to market faster

Streamline the development and maintenance of your products. Azure Sphere is designed for efficiency and comes with a set of Visual Studio tools that will completely change how you create and manage MCU-powered experiences. Azure Sphere is designed to connect quickly and easily to Azure, but our open approach means that you’re able to use Azure Sphere alongside the public or private cloud of your choice.

Create the future

IoT is no longer science fiction. Azure Sphere brings the promise of a secured connected future to MCU devices everywhere. Azure Sphere MCUs deliver unmatched computing power and built-in connectivity that pave the way for next-generation experiences. Azure Sphere enables you to reimagine everything from business models to product experiences. Delight customers with intelligent products that predict and respond to their needs.

Meet the newest class of microcontrollers, plus the OS and cloud technologies that secure them

Azure Sphere brings together the best of Microsoft’s expertise in cloud, software, and device technology to provide a unique approach to security that starts in the silicon and extends to the cloud. Together, Azure Sphere MCUs, the Azure Sphere OS and the Azure Sphere Security Service provide you with the confidence to reimagine your business and the tools to create the future.

Secured MCU

Secured from the silicon up. Our new crossover class of MCUs now combines both real-time and app processors with built-in Microsoft security technology and connectivity.

Secured OS

An OS purpose built for security and agility to create a trustworthy platform for new IoT experiences. Our secured OS builds security innovations pioneered in Windows into an HLOS small enough for MCUs.

Cloud security

Protect devices with a cloud built for IoT security. The Azure Sphere Security Service renews device security, identifies emerging threats and brokers trust amongst device, cloud and other endpoints.

    • Secured MCU

      Azure Sphere MCUs: A new crossover class of MCU with built-in Microsoft security technology and connectivity, and the headroom to support dynamic new experiences.

      The Pluton security sub-system creates a hardware root of trust, stores private keys and executes complex cryptographic operations.

      A new crossover MCU combines the versatility and power of a Cortex-A class processor with the low overhead and real-time guarantees of a Cortex-M class processor.

      Built-in network connectivity provides secured, reliable, online experiences and ensures that devices are up to date.

    • Secured OS

      The Azure Sphere OS: A highly secured OS from Microsoft that creates a trustworthy defence-in-depth platform for new IoT experiences.

      Secured app containers compartmentalise code for agility, robustness and security.

      On-chip connectivity services secure your connection to the cloud and provide access to the Azure Sphere Security Service.

      A custom Linux kernel enables silicon diversity and innovation.

      A security monitor guards integrity and access to critical resources.

    • Cloud security

      The Azure Sphere Security Service: A turnkey security service that guards every Azure Sphere device by renewing security, identifying emerging threats and brokering trust amongst device, cloud and other endpoints.

      Protects your devices and customers with certificate-based authentication of all communication.

      Guarantees a device’s authenticity and ensures it runs only your genuine software.

      Provides insight into device and app failures and visibility into emerging security threats.

      Responds to threats with automated updates of the Azure Sphere OS.

      Allows for easy deployment of your software updates to your Azure Sphere powered devices.

Modernise your MCU development experience with Visual Studio

Install the Visual Studio Tools for Azure Sphere to get started with writing apps. These tools include app templates, development tools and the Azure Sphere software development kit (SDK).

  • Simplify and accelerate development
  • Streamline debugging
  • Modernise your development experience

Connect your Azure Sphere devices quickly and easily to Azure IoT

A simple Visual Studio wizard guides you through the process of connecting your device to Azure IoT Hub and adds the code that you need directly into your app.

  • Easily connect your devices to Azure
  • Send telemetry from your device to the cloud
  • Enable device-to-cloud and cloud-to-device messaging

Here’s what Azure Sphere customers and partners are saying

Our silicon ecosystem

The first Azure Sphere chip will be the MediaTek MT3620, which represents years of close collaboration and testing between MediaTek and Microsoft. Other early partners include Arm, who worked closely with us to incorporate their Cortex-A app processors into Azure Sphere MCUs.

We’re also working closely with leading silicon manufacturers to create a broad ecosystem of vendors who can use their expertise to design specialist chips for various markets. Here are some of the partners who are actively engaged with us to deliver Azure Sphere MCUs along with other partners in the Azure Sphere ecosystem.
