(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. Cisco Duo Makes Secure Logins Simple and Fast **Rating:** 5.0/5.0 stars **Reviewed by:** Avijit S. | Associate technical support, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** April 14, 2026 **What do you like best about Cisco Duo?** I really like how Cisco Duo keeps the login process simple while still being very secure. 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. Also, when the network is slow, the login process can feel longer than I expect. **What problems is Cisco Duo solving and how is that benefiting you?** Cisco Duo helps in preventing unauthorized access and keeps company accounts secure. It reduces risk of password breaches and phishing issues. Because of this, we feel more safe while accessing work systems from anywhere, which is really helpful. ### 4. 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. ### 5. Reliable Two-Factor Authentication with Hassle-Free Cross-Device Use **Rating:** 5.0/5.0 stars **Reviewed by:** Hyacinth B. | PHD Fellow, Higher Education, Mid-Market (51-1000 emp.) **Reviewed Date:** January 27, 2026 **What do you like best about Cisco Duo?** I really like how Cisco Duo works very smoothly across devices. It gives me notifications on my phone and while using wearables like my Apple Watch, making it very hassle-free. It's really valuable because I don't need to pull out my phone all the time, especially if I'm in a rush to log in to my computer during classes. 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. It works smoothly across devices including my Apple Watch, making verification hassle-free and quick without needing my phone. ### 6. Trusted, High-Class Security with DUO Push Multi-Factor Authentication **Rating:** 5.0/5.0 stars **Reviewed by:** Pankaj B. | Junior Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 13, 2026 **What do you like best about Cisco Duo?** It has great security and compliance.

There is a user-friendly DUO Push mobile application that we can download on our smartphones, and whenever we need to authenticate on our websites, we can use the notification code to access them. With the DUO Push mobile app, there are also different methods available, such as phone calls, SMS codes, and token functionality. Overall, we can trust the DUO app, and it really helps keep our things secure. They will be having active customer support In case you stuck somewhere. It's easy for use and implementation in any handset it could be IOS or android. I need to use this daily as it's mandatory to authenticate while using the websites. **What do you dislike about Cisco Duo?** There’s nothing to dislike, because they provide high-class security in this scam-filled world and help keep your things secure. **What problems is Cisco Duo solving and how is that benefiting you?** When accessing multiple platforms, it’s very easy to authenticate using different methods from the same application, DUO PUSH. You can use codes, tokens, a phone call, or push notifications to authenticate. Overall, it’s easy to use and a user-friendly application. ### 7. Effortless Security and Identity Verification **Rating:** 5.0/5.0 stars **Reviewed by:** Mike W. | QA/RA Team Lead, Medical Devices, Mid-Market (51-1000 emp.) **Reviewed Date:** April 28, 2026 **What do you like best about Cisco Duo?** I find Cisco Duo extremely easy to use, especially the phone-based application that allows me to quickly and easily verify my identity, ensuring that my privacy and organization security is always a top priority. It enhances security greatly by verifying my identity on the same platform or computer, or across several computers or devices. Our MIS department made the initial setup extremely easy. **What do you dislike about Cisco Duo?** I have no dislikes about Cisco Duo. **What problems is Cisco Duo solving and how is that benefiting you?** I use Cisco Duo to verify my identity across various apps, enhancing security greatly. It's extremely easy to use, especially the phone app, making identity verification quick and ensuring my privacy and security are top priorities. ### 8. Simple and Effective Protection with Cisco Duo **Rating:** 4.5/5.0 stars **Reviewed by:** Angel B. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** January 21, 2026 **What do you like best about Cisco Duo?** What I like most about Cisco Duo is the push feature, which allows me to receive a notification and simply press the approve button, without having to search for and copy a 6-digit code. Additionally, I love that I can use it from my watch, which allows me to approve access without having to take out my phone, saving me from distractions. It is much faster and safer than using slow text messages or searching for passwords in authentication tools. **What do you dislike about Cisco Duo?** Well, it's that if I don't have my phone on hand, or I ran out of battery, or I don't have my watch on hand, well, my smartwatch, then I'm blocked, and I can't access anything. It would be good to have more backup options that are easy to use without having to contact technical support. The process of changing devices is a bit tedious because you have to go back to and if I don't have the IT administrator, it's necessary. See all those issues, so that's what makes it difficult for me. **What problems is Cisco Duo solving and how is that benefiting you?** I use Cisco Duo to protect my email accounts, VPN, and CRM, ensuring that the information is secure. It helps me authorize logins easily, quickly, and intuitively, avoiding the issues with text messages that don't always arrive. ### 9. Effortless Security with Multi-Factor Authentication **Rating:** 4.5/5.0 stars **Reviewed by:** Abhi Y. | Network Engineer, Manufacturing, Mid-Market (51-1000 emp.) **Reviewed Date:** January 21, 2026 **What do you like best about Cisco Duo?** I like how easy Cisco Duo is to use and deploy. The push-based authentication is quick and user-friendly, allowing users to approve access with just one tap, which reduces login delays. The deployment integrates easily with existing systems, saving setup time and effort. We value Duo Push the most because it provides fast, secure authentication with minimal user effort, and its easy integration for VPN and application access.
