Device Health

The Duo Device Health Application is an application installed on your desktop or laptop that performs health checks whenever you access Duo protected applications, ensuring that your computer meets the organization’s security requirements. This helps protect corporate data and make sure your computer is less vulnerable to compromise.

Vulnerable laptops or desktops accessing corporate resources exposes organizations to potential attacks, financial damage and compliance issues. Duo's Device Health Application reduces risk by ensuring compliance of corporate devices to business standards and provides visibility into personal devices before granting them access to corporate resources.

Duo Device Health supports the following platforms:

  • Windows 10 client editions, including Enterprise, Pro, and Home.
  • macOS 10.13 and later.

Duo Device Health application does not support Windows Server, earlier versions of Windows, or macOS beta versions.
