Why we invite security researchers to hack Azure Sphere
Fighting the security battle so our customers don’t have to IoT devices are becoming more prevalent in almost every aspect of our lives—we will rely on them in our homes, our businesses, as well as our infrastructure. In February, Microsoft announced the general availability of Azure Sphere, an integrated security solution for IoT devices and equipment. General availability means that we are ready to provide OEMs and organizations with quick and cost-effective device security at scale.
Azure Sphere’s customized Linux-based OS
Security and resource constraints are often at odds with each other. While some security measures involve making code smaller by removing attack surfaces, others require adding new features, which consume precious flash and RAM. How did Microsoft manage to create a secure Linux based OS that runs on the Azure Sphere MCU? The Azure Sphere OS begins with a long-term support (LTS) Linux kernel.
Unlock new features in the MT3620 MCU with the Azure Sphere 19.05 release
Each quarter, the Azure Sphere team works to open new scenarios to customers through new features on-chip and in the cloud. The Azure Sphere 19.05 release continues this theme by unlocking the real-time capable cores that reside on the MT3620.

What’s the difference and what does it mean for you? The Retail feed provides a production-ready OS and is intended for broad deployment to end-user installations.
Guardian modules: Bringing Azure Sphere security to brownfield IoT
When someone mentions the words “Internet of Things,” often the first picture that comes to mind is some sort of device with the Internet “built-in.” However, a built-in design involves months or years of design work and applies only to devices that have yet to come to market. How do businesses leverage IoT for the billions of devices already in the field without creating a large security risk?
