Overview

Product Information on Duo

Updated 23rd September 2025

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.

Duo Pricing

Duo offers three pricing tiers: Essentials ($3/user/mo) includes security-first IAM, phishing-resistant MFA, passwordless, SSO, AI Assistant, and Trusted Endpoints. Advantage ($6/user/mo) adds continuous identity security, cross-platform visibility, posture management (ISPM), and threat detection and response (ITDR). Premier ($9/user/mo) adds VPN-less remote access via Duo Network Gateway.

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

Like

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.

Like

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

Like

Duo offers multiple user-friendly authentication options, such as push notifications, static passcodes for offline access and Bluetooth-based proximity authentication. These flexible methods have made it easier to gain user acceptance, even among those initially resistant to change.

Dislike

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.

Dislike

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.

Dislike

We have not encountered any major issues or user complaints since implementation. In addition, Duo has proven to be reliable, intuitive and seamless making it an essential pillar of our ISO-27001 aligned Information Security Management System.

    Cisco Duo Enhances Security With Flexible Multi-Factor Authentication Options

    4.0
    Aug 7, 2025
    Our overall experience with Cisco Duo has been excellent. We adopted Duo as part of our broader initiative to enhance our cybersecurity posture, specifically in response to a significant increase in attack attempts involving compromised credentials found on the deep web. Duo has played a critical role in mitigating these threats by adding a robust layer of multi-factor authentication (MFA), effectively stopping brute-force and social engineering-based login attempts

    DUO has been an outstanding solution for us. It has helped us implement two-factor authentication for more applications than we ever imagined, with enough two-factor options to accommodate every user. Administration is relatively simple, allowing us to push much of the day to day user administration to our helpdesk, freeing our engineers to work on other things.
