What is Duo?

Cisco Duo provides security-first Identity and Access Management (IAM) that protects organizations from identity-based threats. Duo includes all the necessary components to serve as your sole IAM platform or seamlessly integrate with and fortify your existing identity providers, operating as a unified defense layer across your identity infrastructure. By embedding critical protections like broad-based MFA and device trust into the company’s base offering, Duo eliminates the "security tax" often imposed by traditional IAM vendors. Essential security is on by default—not a costly, complex upgrade. As a result, Duo addresses advanced threats while delivering a seamless experience that users and admins embrace.

Performance of Duo Across Market Features

Duo Likes & Dislikes

Duo balances strong security with a user-friendly design. The platform integrates smoothly with our existing systems, offers clear visibility into authentication activity, and provides flexible options for enforcing MFA policies. The support and documentation have also been excellent, which has made deployment and troubleshooting much easier.

it's mostly easy to support. easy to add apps to the SSO expreince. decent documentation

The dashboard is excellent and simple. The app is great and migrating your MFA setup to a new device is made really simple. We were able to transition to passwordless authentication for our remote access with Cisco Duo and Anyconnect, for increased security and simplicity. Active Directory Integration was seamless and allows us to manage users and groups from a single place and the changes are reflected in the Duo dashboard. So the product has been an all around great experience to set up and manage.

Not much to hate. Just wish there was better accessibility for the Duo Windows Login when prompted with a number challenge. The number is small and users struggle to locate it promptly. It would also help if there were more customizations for the Windows login prompt (like adjusting size or color contrast for accessibility). Lastly, offline login handling could be smoother; users sometimes get confused when there's no clear indication of what to do without an internet connection. I also think it would be helpful to every so often prompt the user for a re-enrollment for offline (make it optional) so it might catch those who get new phones and miss re-enrollment for offline.

Unable to back up the client. They expect you to use google to back up the DUO client but google is often blocked due to DLP restrictions and even when it is not blocked, users still have problems backing up DUO. Moving from one phone to another phone is a HUGE horrible experience. losing access to websites and having to contact each vendor to gain access again can take days and even weeks.

The documentation on the installation of the authentication proxy was outdated, and I encountered some errors, because the file structure was different, but nothing that we didn't figure out quickly, and made it work. The extra features, such as the Duo Passwords and SSO capabilities, could be better explained.

Feb 19, 2026
Easy to get started and set up, we installed the duo authentication proxy and it took no longer than a day to get it up and into the testing phase. The management dashboard is really simple and great to work with, user management is made simple with AD connection, so all users added to ad can be replicated over to the dashboard.

Duo MFA Enables Secure Access but Faces Challenges With Console Navigation
5.0
Feb 26, 2026
Duo has been a reliable MFA solution in our enterpirse providing seamless push notifications and device trust secure access to servers and apps. setup was easy via the admin consolem integrating well with RADIUS and SAML. Minor drawbacks include occasional offline limitations and console navigation for complex polices, but support responsiveness and phishing-resistant features make it a top choice for baking-grade security

Consistent Support and Product Adaptability Noted Despite Minor Mobile App Frustration

Feb 25, 2026
The original implementation was very smooth. They made sure I understood why things were being setup the way they were and provided the training to continue adding integrations myself. We have the Duo Care support package and in the past 3-and-a-half years have had our primary technical support rep change a couple of times, but each technician has been extremely knowledgeable and a couple of them have even helped with some issues we were having on the OS side. We have maintained the same Customer Success Specialist throughout and she is amazing. Overall, the product and support have been outstanding.

It's very straightforward. Users feel indifferent towards it, however it is a great security tool. It is simple to set up, and there are multiple ways of solving an issue if there is one.
