Today, IoT is more advanced than ever before. Since its emergence, it has contributed to many technological changes and has paved the way for new innovative breakthroughs. Especially, when you take a look at the market for the Internet of Things, it is rapidly growing to such an extent that from a simple smart TV to an automated robot, millions of devices are now connected to the cloud. One of the main concerns with connected devices is security. Sometimes, devices are often connected to networks without considering security, hence paving the way for unwanted, harmful malware to enter the device easily. What’s making it worse is that maybe the devices are rarely updated, running the same insecure firmware as from day one. Therefore, increasing security risks and vulnerabilities. 

So how can we make it secure and keep the devices safe? This is where Microsoft’s Azure Sphere falls into the picture.

What is Azure Sphere?

According to Microsoft’s documentation website, Azure Sphere is defined as ‘a secure, high-level application platform with built-in communication and security features for internet-connected devices.’ 

Microsoft’s defense-in-depth IoT platform mixes software, hardware, and the cloud to protect your network and your devices from unwanted access into the system. This solution also involves an application platform and an operating system. This renders product manufacturers with a possibility to build secure, internet-connected devices that can be regulated, monitored, updated, and maintained remotely. There are three main components for Azure Sphere. They include Secured MCU, Secured OS, and Cloud Security. 

Three Main Components For Azure Sphere

1. Secured MCU

This is the first component of Microsoft’s Azure Sphere. It is a  crossover class of MCU. It has built-in Microsoft security technology and connectivity. 

2. Secured OS

The second component is a profoundly-secured operating system from Microsoft with a customized element working on top of Microsoft’s Security Monitor. This provides a reliable defense-in-depth platform.

3. Cloud Security

The third component secures every Azure Sphere device by recognizing emerging threats, rebuilding security, and ensuring trust between devices and the cloud. 

Five Benefits of Azure Sphere


1. Defense in Depth

This is regarded as the fundamental benefit as it provides various layers of protection to help secure devices against and respond immediately to threats. 

2. Deployment Flexibility

Azure Sphere’s deployment flexibility is the reason which assists you to defend the current equipment and strengthen protection into new IoT investments.

3. Over-the-air (OTA) Updates

 This is the update that makes it easy for your devices to add new features and enhance performance throughout device lifecycles.

4. Reports Error and Automatic Security Updates

This is another benefit that allows your devices to report ongoing errors and help you stay ahead of new and evolving threats.

5. Connectivity Supports

Despite all the other benefits Azure provides, this might be one of the most common as well as one of the most beneficial aspects. That is, it supports wireless connectivity, ethernet connectivity, Bluetooth LE connectivity, and cellular connectivity throughout devices. 

How does Azure Sphere Protect its IoT Deployments?

Azure Sphere has been widely popular among major companies, such as Starbucks, Purell, and Elettrone because of the vast advantages it provides as well as how it protects their IoT deployments. 

  • Azure Sphere-certified Chips- 

The certified chips from hardware partners comprise built-in Microsoft security technology to implement a reliable hardware root of trust as well as seamless connectivity. 

  • Azure Sphere Security Service

The security service of Azure Sphere mainly focuses on three factors. They are- it ensures trust for device-to-cloud communication, renews IoT device security, and detects new incoming threats.
