Maximize the value of equipment that’s already in place
Bring the benefits of connectivity to legacy equipment that’s already in service—brownfield equipment—without exposing it to the internet. With an Azure Sphere guardian module, IoT retrofits are more secure, substantially easier, and more cost-effective than ever.
Build new IoT devices that stay highly secured
With Azure Sphere, manufacturers and solution providers can build devices that are secure from the start and that stay secure throughout the device lifetime. Give your customers differentiated value and peace of mind while growing your business. Research by Greenberg Strategy shows that security can help drive market share.
The seven properties of highly secured devices
Our research on bringing high-value security to low-cost devices identified seven essential properties needed to make devices highly secured. Easily build these properties into your IoT with Azure Sphere.
Hardware-based root of trust
This guarantees that a device is running only genuine, up-to-date software before it can connect to the rest of the internet.
Defense in depth
More layers of defense make it harder for an attacker to gain access to a device’s most sensitive secrets. More sensitive areas are put behind greater layers of defense.
Small trusted computing base
A trusted computing base should be kept as small as possible to minimize the surface that’s exposed to attackers and to reduce the probability that a bug or feature can be used to compromise it.
Boundaries between software components can prevent a breach in one component from propagating to others. Dynamic boundaries can be moved and redrawn safely.
Passwords can be the weakest link in many security systems. Certificate-based authentication eliminates the need for passwords to manage a device.
Early detection, analysis, and response to errors is critical to stopping threats before they cause significant damage.
The ability to deploy ongoing software updates is essential to tightening a device’s defenses and shutting down vulnerabilities.
Our hardware ecosystem
A global network of Microsoft partners delivers revolutionary new IoT hardware—from microcontroller units (MCUs) and crossovers to modules, development kits, and guardian devices—to bring Azure Sphere to a broad range of customers and applications.
Microsoft works with silicon partners who create Azure Sphere–certified chips. These chips are the heart of every Azure Sphere–based device. They contain Microsoft security technology that enables end-to-end, secured connectivity and a hardware root of trust.
This cross-over class of MCU includes built-in Microsoft security technology and built-in Wi-Fi connectivity, and combines the versatility and power of an Arm Cortex-A7 processor with the low overhead and real-time guarantees of a Cortex-M class processor.
Get up and running quickly and easily test different hardware designs. Azure Sphere development kits feature on-board LEDs and buttons, easy-to-use connectors, and integrated programming and debugging circuitry compatible with the Azure Sphere SDK.

Modules for new IoT devices
Build new, connected devices with Azure Sphere modules. One of the challenges of device design is ensuring that Wi-Fi performs well and complies with applicable regulations. These modules remove this obstacle and reduce time to market by providing a tested and production-ready Wi-Fi radio subsystem that’s built around an Azure Sphere–certified chip. Modules provide a range of integrated functionalities and regulatory certifications for target use cases.
This production-ready, dual-band Wi-Fi module is available in two versions: with an integrated antenna and with an external U.FL antenna connector. Both versions are pin- and footprint-compatible. The stamp-hole (castellated) pin design simplifies quality assurance.
This single-band Wi-Fi module is designed for cost-sensitive applications. It simplifies quality assurance with stamp-hole (castellated) pin design.

The product is designed for greenfield applications and supports cellular (2G, 3G, 4G), dual-band WiFi, ethernet (WAN) to connect to Microsoft Azure. For geo-positioning it is equiped with GNSS and qMAPS. This product is pin-compatible to its 5G IoT compagnion the Concentrator XNL.
qiio Concentrator XNL
The 5G IoT compangion of the Concentrator XN supports cellular (5G IoT (LTE-M, NB2)), dual-band WiFi, ethernet (WAN) to connect to Azure. For geo-positioning it is equiped with GNSS and qMAPS. This product is pin-compatible to its LTE IoT compagnion the Concentrator XN.
Guardian modules for retrofitting existing equipment
Guardian modules provide a quick path to securely connect existing equipment that either doesn’t support connectivity or doesn’t support it securely. A guardian module serves as an intermediary by physically attaching to the equipment via an existing peripheral and to the internet via Wi-Fi or Ethernet. The critical equipment itself is never exposed to the internet. Guardian modules often come as complete hardware solutions.
Avnet Guardian 100
The Avnet Guardian 100 attaches to and secures existing equipment via Ethernet or USB, and securely transfers data to and from the cloud over dual-band Wi-Fi.
qiio q200 Guardian
This worldwide cellular device for brownfield IoT applications works from the edge to the cloud upon delivery. It comes ready with embedded software and fully integrated with Azure. Must be prototyped first with qiio development kit.
