We didn't have MFA for our server logins until we adopted ManageEngine. Price was the deciding factor. The economy is in the dumps, so our IT budget's pretty tight. We also needed something that could grow along with our company. If we ever need to enable MFA for all employees, it's already in place and ready to go.

This is the first time I'm using such a product. 

We did not use another solution prior to ADSelfService plus. It was part of our change in security posture over the past couple of years. Our struggle was finding a product that could do what we needed to do at our price point.
