Duo Device Health

Feinberg’s current device security apps, BigFix and F5/Big-IP will be replaced by Duo Device Health (DDH). This change will provide a superior user experience while advancing Feinberg IT security measures. DDH verifies that desktop and laptop computers have supported operating systems, encryption, and anti-virus software before allowing access to multi-factor authentication-enabled university resources, including email.

For more information and to learn about what you can do to prepare for the change, please review our Frequently Asked Questions below. If you have additional questions about Duo Device Health, please contact via email.


Frequently Asked Questions

 What is the Duo Device Health application?

 Why is the Duo Device Health application important?

The Duo Device Health application reduces risk to the university by checking your device for disk encryption and the presence of anti-malware that prevents unwanted access to university data and resources.
