There aren't any new features or functionalities in Cisco Duo that my company has started using recently; we use it primarily for the authentication portion. There are other features we can use, yet we haven't turned those options on yet, so that's more a matter of time than anything. We have many different vendors and types of devices that we require MFA for login. That said, Duo helps bring all of those accounts into one system, in conjunction with ISE, you have one username, one password, and you access all the devices instead of having every device have its own credentials. It lowers the number of passwords you need to have. Cisco Duo is on the right track for improvement. A lot of their devices already integrate with it now. They keep adding features for more devices that interact natively with it, instead of having to have a third-party server to reach out to Duo. I would rate Cisco Duo overall about an eight out of ten; it's a strong product.
