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.

What i appreciate most about Duo is how reliably it delivers strong security without creating friction for our users. The platform strikes a rear balance, it enforce robust authentication and adaptive access controls while still keeping the login experience simple and consistent. The SSO capabilities has been major win for our teams, reducing the number of credentials they manage and improving overall productively. From an admin perspective, Duo is straightforward to configure, integrates cleanly with both modern and legacy applications and provides clear visibility into user and device posture.

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.
