Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well.

The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular.

Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system.

Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it. That's my only complaint.

Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition.

When we try to sell Cisco Duo for any license, sometimes customers approach us and say that Cisco Duo is expensive compared to competitors or that the features are not as good.

I would appreciate seeing Cisco Duo improved with a tighter integration with Active Directory to secure not just Remote Desktop to a server, but all the remote levels of connection that you can make to a server.
