Azure Sphere

A new solution for creating highly-secured, connected MCU devices

Azure Sphere can help you securely connect your products at a price point that enables IoT at scale. Our three-part solution brings together the best of Microsoft's expertise in cloud, software, and hardware-resulting in a unique approach to security that starts in the silicon and extends to the cloud.

Secured MCU

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

The Pluton Security Subsystem 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 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 devices are up to date.

Secured OS

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

Secured application containers compartmentalize 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.

A diagram showing the layers of the Azure Sphere operating system. It includes the following layers. OS Layer 0: Hardware. OS Layer 1: Security monitor. OS Layer 2: Custom Linux kernel. OS Layer 3: On-chip connectivity services. OS Layer 4: App Containers for compute and App Containers for real-time I/O.

Cloud Security

The Azure Sphere Security Service. A turnkey security service that guards every Azure Sphere device; renewing security, identifying emerging threats, and brokering trust between 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 application 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.

Many kinds of devices floating in the cloud

Modernize your MCU development experience with Visual Studio

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

  • Simplify and accelerate development
  • Streamline debugging
  • Modernize 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 you need directly into your application.

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

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 application 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 specialized chips for various markets. Here are some of the partners who are actively engaged with us to deliver Azure Sphere MCUs and other partners in the Azure Sphere ecosystem.
