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.

Our Duo Care team has been incredibly helpful and responsive to every issue. They've shown great patience throughout our rollout, even as we've taken a slower, more methodical approach to deployment.

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 things that I like the most are : 1) Easy MFA methods for users, duo push is very handy 2) strong security without impacting any user - 3) Visibility - The visibility is very good as it shows granular visibility about users, their auth method, device, time, policy applied, etc 4) Centralized admin console - use duo dashboard to manage apps, policies, users, SAML, etc.

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.

Things which I found as hinderence in the DUO are : 1. Network connection - it requires a good network connection to sync updates and policies and under bad netowrk there might be delays . 2. integration - integration with certain apps and components requires complex and additional configuration 3. offline access - available but a bit complex process

My overall experience with DUO has been great, it provides strong MFA for various components of the network, its easy to deploy and manage, the dashboard UI is very user friendly, its very stable and a good MFA solution. Integrates well with firewalls, VPN, AD and apps. The user experience is very good and it is widely accepted by the users . It aslo acts as sevice provider and Identity provider for other apps and components

Multi Factor Authentication Adds Security But Repeated Approvals Cause Occasional Delays

Jan 28, 2026

Duo makes user authentication much easier and the setup process is so simple and straight forward that I don't need to put in much effort. It has a wide range of options for integration which makes it much more reliable to use.
