(12 reviews) ## Cisco Duo Reviews ### 1. Strong Device Visibility and Access Control, but Offline Codes Can Be Cumbersome **Rating:** 3.5/5.0 stars **Reviewed by:** Robert B. | Lead Support Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 23, 2026 **What do you like best about Cisco Duo?** What I like best about Cisco Duo is the visibility it gives us into user devices and how easy it is to control which devices can access our systems. That added layer of device awareness helps us enforce stronger access policies and gives us more confidence that only trusted devices are being used. It is especially helpful from a security perspective because it makes it easier to manage access without creating too much friction for users. **What do you dislike about Cisco Duo?** What I dislike most about Cisco Duo is that administering offline codes for server access can be frustrating, especially in environments where reliable fallback access is important. While the platform works well overall, some administrative tasks can feel more cumbersome than they should be. There is also a learning curve when configuring more detailed access policies. **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo helps us secure remote access by integrating well with our remote access solution and giving us better visibility into where people are connecting from. Before that, we had less insight into access activity and fewer controls around remote logins. Now we can apply stronger authentication, see more clearly where access attempts are coming from, and make better decisions about who should be allowed in. That improves security, reduces access risk, and gives us more confidence in our remote access process. ### 2. Cisco DUO has been our most reliable 2FA solution so far **Rating:** 5.0/5.0 stars **Reviewed by:** Jason L. | Network Administrator, Retail, Small-Business (50 or fewer emp.) **Reviewed Date:** April 21, 2026 **What do you like best about Cisco Duo?** Cisco DUO is very intuitive for both the end user and admins alike. The DUO app works with all kinds of mobile devices that I have come across and appears to stay up to date. The DUO solution is integrated with our Cisco Firewall solution so it is easily managed. The App performs very quickly, though it does rely on a decent network connection of almost any type. Cost associated with DUO is very reasonable compared to other solutions, and support is very good. **What do you dislike about Cisco Duo?** There is not much to say here, other than the DUO Push solution is sometimes too qick. The end user does not expect it to only allow them about 7 seconds to approve the prompt. However this is almost always a breif learning curve to just be prepared when you hit confirm on the laptop knowing the prompt on your mobile device is following asap. **What problems is Cisco Duo solving and how is that benefiting you?** We use this as 2FA to confirm VPN credentials and connect to our internal network for remote Team members. ### 3. Smooth, No-Code MFA with Robust Device Visibility and Easy Admin Dashboard **Rating:** 4.5/5.0 stars **Reviewed by:** Luciana S. | IT Manager , Health, Wellness and Fitness, Mid-Market (51-1000 emp.) **Reviewed Date:** May 18, 2026 **What do you like best about Cisco Duo?** Cisco Duo creates a smooth login experience, and this involves a simple MFA solution that needs no coding The program has efficient push notifications capabilities, and this supports users in adopting the app instantly Cisco Duo provides a robust device visibility, something that helps the IT team to develop solid access policies The software effectively integrates with cloud apps, VPNs, and other identity providers The dashboard is designed with easy navigation systems and this helps admins and IT teams to manage authentication processes The program operates successfully with companies that are both small or large and no operational frictions **What do you dislike about Cisco Duo?** Often, Cisco Duo delays push notifications, and this happens when there is poor connectivity The app demands advanced policies configuration and this affects performance and efficiency **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo is a helpful approach and it protects users from phishing attacks and credential theft The program issues brilliant remote security, and this includes use of VPNs The program supports companies to meet all organizations cybersecurity requirements and compliance The risk of unauthorized access is also largely eliminated by this app, and this involves analyzing passwords vulnerabilities The IT team obtains centralized visibility, something that increases authentication and ensures all devices involved are intact and protected The app supports cloud apps security, and this involves proper access management ### 4.

We use Cisco Duo for authentication for our company portal. It provides a six-digit code that you need to enter, and only then are you able to successfully log in to the company portal, AWS, and GitLab. **What do you dislike about Cisco Duo?** One thing I dislike about Cisco Duo is that push notifications can sometimes arrive late, especially when my internet connection is slow. **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo helps us secure company applications and VPN access through multi-factor authentication.

The push notifications come through quickly and are easy to approve. Overall, it does a great job of helping keep accounts safe without making things overly complicated for users. **What do you dislike about Cisco Duo?** One thing I don’t like about Cisco Duo is that the push notification sometimes arrives late or doesn’t come through right away, which can be frustrating.

Efficient MFA with Room for Improvement **Rating:** 3.5/5.0 stars **Reviewed by:** dennis s. | IT Supervisor, Mid-Market (51-1000 emp.) **Reviewed Date:** April 30, 2026 **What do you like best about Cisco Duo?** I appreciate Cisco Duo's efficient technical support, which helps solve all technical challenges I encounter. The Trusted endpoints feature is valuable for preventing non-work devices from connecting to our environment, enhancing security. The push authentication is lightweight and easy to accept, offering security with a level of convenience. Additionally, the initial setup of Cisco Duo was very easy. **What do you dislike about Cisco Duo?** It lacks full integration with critical components of Microsoft RD Web Solution, which would enable us to verify users using a passcode for users who don't have the Duo MFA app. Cisco needs to ensure that there is support for critical Microsoft remote connection implementation as it is widely used. **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo adds a second layer of authentication, reducing password compromise risks. It protects remote access and helps block unauthorized devices. It solves issues like phishing, credential theft, and weak passwords while offering convenience through push authentication. ### 8.

The prompt through my Apple Watch is very easy, it's like a split second, and I can just confirm and verify my identity. The setup was very easy, so much so that I don't even remember how it was done. It didn't take me long at all to get it set up. **What do you dislike about Cisco Duo?** There is nothing that I dislike about Cisco Duo. **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo helps me confirm my identity to prevent unauthorized access with reliable two-factor authentication.
