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.

    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

    Jun 16, 2025
    It is easy to use and set up. It did not take me long to add a new user to the dashboard. I do have the option to add users by CSV file. Also it is very self explanatory when you are sending a new user a message to get their cell phone set up.
