Over the last few months, Microsoft has been expanding and changing the landscape of its Defender security suite. Mobile Network Protection arrived recently for enterprise, while consumers Defender has become a cross-platform service. In the latest expansion, Microsoft Defender for IoT is launching as a new security tool for printers, smart TVs, and other connected devices.

Microsoft Defender for IoT provides a complete monitoring system for the Internet of Things devices, specifically those on enterprise networks. It focuses on business devices such as operational technology (OP), Voice over Internet Protocol (VoIP), and printers.

“With this new addition, Defender for IoT now delivers comprehensive security for all endpoint types, applications, identities, and operating systems,” says Michal Braverman-Blumenstyk, Microsoft corporate vice president and chief technology officer of cloud and AI security, in a blog post.

“The new capabilities allow organizations to get the visibility and insights they need to address complex multi-stage attacks that specifically take advantage of IoT and OT devices to achieve their goals.

Customers will now be able to get the same types of vulnerability management, threat detection, response, and other capabilities for enterprise IoT devices that were previously only available for managed endpoints and OT devices.”


With Defender for IoT, Microsoft wants organizations to be able to extend their security visibility beyond the devices they manage. Through automatic scanning, the service can find insecurities in configurations across a network.

The feature set includes finding flaws that have not yet had a patch and then supplying security recommendations. These tips will be sent to the Microsoft 365 console so admins can see them easily.

Tip of the day: To prevent attackers from capturing your password, Secure Sign-in asks the user to perform a physical action that activates the sign-in screen. In some cases, this is a dedicated “Windows Security” button, but the most common case in Windows is the Ctrl+Alt Del hotkey. In our tutorial, we show you how to activate this feature.
