Overall Satisfaction with Duo Security

Our organization is using Duo for dual-factor authentication of our single sign-on logins across platforms and devices. It allows our user authentication process to be more secure, which is important because there have been a large number of phishing attempts sent to our employees via email over the past few years.


  • Duo Security has a convenient mobile app, so all our employees can implement it and login when and where they need to.
  • The app is streamlined and simple, and doesn't contain ads or unnecessary features.
  • Duo Security allows our employees to not only use it for their company login, but for external logins as well, so all of their dual-factor authentication data is in one app.


  • Sometimes when trying to authenticate external accounts with Duo, I have issues where the external login doesn't accept the code that Duo generates.
  • I wish the codes that Duo generates would last longer before expiring.
  • Duo doesn't work well with Amazon logins - I had to turn 2-factor authentication off for Amazon in order to log in, after connecting it to Duo.
  • Duo Security allows our IT department to have more bandwidth to deal with other security issues.
  • Duo Security gives our employees greater peace of mind that their accounts are not going to be hacked.
  • Our organization saves money by not having to purchase separate security key generator dongles for all employees.
Cisco Multi-Factor Authentication is pretty easy to use as an end-user once it has been configured by your company's IT department. It works from a mobile device and doesn't require any additional hardware, so it is convenient for the average user. It's not always easy to connect it to applications outside of your company, though.
Our company has definitely benefited from using Cisco's MFA because our user authentication across our Active Directory is more secure. We receive a lot of phishing attempts via email, but the dual factor authentication helps to keep our employees' accounts from being completely hacked by phishing attempts. Even if their email is compromised, the phishing attempt does not allow the hacker to log in to the Active Directory account because they don't have the Duo authentication info.
I honestly haven't had any experience working directly with Duo Security's support team. However, I have had contact with my company's IT when it comes to Duo Security support, and it seems that they have supported our IT department enough for our IT to be able to help our organization's employees troubleshoot effectively.
I don't have an example for this because I have not interacted directly with Cisco's Duo Authentication support.
Duo Security works well for corporate logins where all users are on the same Active Directory system. It is a more modern and cost-effective authentication method than the old security code generator dongles. I would not recommend using Duo if you have a lot of remote or contract employees whose logins aren't managed in the same directory as everyone else.
