Duo Desktop is a security utility designed to enforce device health requirements before granting access to Duo-protected applications on Windows systems. This tool, formerly known as Duo Device Health, empowers organizations by controlling which devices can connect based on their security posture. The main features include customizable access policies, a native client for multiple operating systems, and enhanced endpoint information accessible via the Duo Admin Panel.

The functionality of Duo Desktop is centered around its ability to perform health checks on devices during user authentication. If a device does not meet the required security standards, access to applications is blocked, and users are provided with guidance on how to rectify their device's security issues. This proactive approach ensures that only secure devices can access sensitive corporate resources, significantly improving overall security posture.
