How are customer service and support?
Cisco Duo's customer support needs improvement.
How would you rate customer service and support?
Negative
Which solution did I use previously and why did I switch?
I previously used a different solution for two-factor authentication from Fortinet.
What was our ROI?
I have seen a return on investment, and I can share relevant metrics with savings in money. Cisco Duo has helped my organization in reducing overall authentication-related costs, with an estimated savings of about half of authentications.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing reveals that one of the most powerful features is the licensing model and the price. According to the pricing, it is really fantastic to get this value compared with other vendors.
Which other solutions did I evaluate?
Before choosing Cisco Duo, I evaluated other options such as FortiAuthenticator.
What other advice do I have?
My advice to others looking into using Cisco Duo is that it is really helpful for implementing zero trust and enforcing two-factor authentication for many users. Additionally, the licensing model is one of the best features; you can purchase licenses only for the number of users you have, whether it is 50 or 20.

Uses secure mobile push and code-based authentication to improve user login process
Pros and Cons
- "The authentication process is very smooth and secure."
- "I faced a significant issue about a year back when I tried to integrate Cisco Duo with Citrix NetScaler and enable MFA for Citrix NetScaler integration."
What is our primary use case?
I have been using Cisco Duo for one of my customers for three years. I have integrated Cisco Duo with the on-premises Active Directory and I am using two authentication methods: one is by code and one is through push notifications on Android mobile phones or Apple iPhones. The authentication process is very smooth and secure.
When any request is made to log in for email, the request is integrated with Cisco Duo and asks the user to enter a code via their mobile phone. This is the purpose I am using it for, and it represents a very smooth and secure authentication method.
How has it helped my organization?
The method is simple and secure, only thing i want to say about pricing will be reduce for old customers
What is most valuable?
Cisco Duo has a capability for Duo Push. When it comes to authentication, you get a notification and you just need to approve or reject the request, which allows the process to go smoothly. Although Microsoft Authenticator also has this function, other authenticators do not.
What needs improvement?
Pricing is an area that needs improvement because the pricing is high. One of my customers recently received a billing statement for one year charging 3,600 US dollars for 100 users. In my case, it costs me around 300 US dollars monthly for 100 users.
Initial deployment was smooth from an MFA point of view. However, I faced a significant issue about a year back when I tried to integrate Cisco Duo with Citrix NetScaler and enable MFA for Citrix NetScaler integration. I encountered a lot of issues during the integration part and was unable to achieve that task due to a lack of documentation at that time. That project was eventually closed.
For how long have I used the solution?
I am using Cisco Duo for one of my customers for three years.
What do I think about the stability of the solution?
I have not faced any issues with Cisco Duo so far. It is a very stable product and functions well.
What do I think about the scalability of the solution?
Scalability is good with Cisco Duo.
How are customer service and support?
The support process is very smooth. If I need any support, I can send an email to their support team and they reply on the same day. I normally send emails to billing support and have not needed to send support emails otherwise until now.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I have used AuthLogics MFA as well. I am also using Google Authenticator and Microsoft Authenticator.
How was the initial setup?
Cisco Duo is a very simple product to understand. I searched for information on Google and integrated it using the guide provided by Cisco Duo during my first implementation. If I need any support, I can send an email to their support team and they reply on the same day. The support process is very smooth and initial deployment is smooth from an MFA point of view.
What's my experience with pricing, setup cost, and licensing?
Pricing needs improvement because it is high. One of my customers recently received a billing statement charging 3,600 US dollars for 100 users for one year. In my case, it costs me around 300 US dollars monthly for 100 users.
Which other solutions did I evaluate?
I have used AuthLogics MFA as well. I am also using Google Authenticator and Microsoft Authenticator.
What other advice do I have?
My clients are requesting MFA on their emails, third-party emails they are using for HTTPS, for cloud emails or cloud logins with different applications. I recommend Cisco Duo to them because the process is very smooth with Cisco Duo. I give Cisco Duo a rating of 10.
Which deployment model are you using for this solution?
On-premises
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Secure logins and device updates have boosted our confidence in online access
Pros and Cons
- "The feature of Cisco Duo that I value the most is that it's easy to use; it monitors all our devices to ensure everything is updated before we're given access to those applications."
What is our primary use case?
Our main use cases for Cisco Duo are for our own internal systems and applications that we're using, finance related and sales related.
How has it helped my organization?
Simplicity in doing our secured authentication
What is most valuable?
The feature of Cisco Duo that I value the most is that it's easy to use. It monitors all our devices to ensure everything is updated before we're given access to those applications. Our company benefits from all those features of Cisco Duo with confidence, and we feel very secure with it in terms of authentication of our logins.
What needs improvement?
As for improving Cisco Duo, we're quite happy with it, so there isn't much negative feedback. I would mention that there's nothing specific I would want to see enhanced in Cisco Duo. We're very satisfied with it, and there haven't been any requests from the team for enhancements or future features. Everyone has been very happy with it.
For how long have I used the solution?
I have been using Cisco Duo for 5 years.
What do I think about the stability of the solution?
As for the stability and reliability of the solution, we have never had any issues. We have never experienced any downtime.
What do I think about the scalability of the solution?
Cisco Duo scales very with the growing needs of our company; it's very easy for us to upgrade or add licenses or do additional deployments for our new employees or new hires. If there are new devices coming in, it's very easy to implement.
How are customer service and support?
Regarding customer service and technical support for Cisco Duo, we don't have issues with that because we're quite skilled with it.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Before choosing Cisco Duo, I didn't consider any other solutions.
How was the initial setup?
The deployment of Cisco Duo is a very simple process for us.
What about the implementation team?
For our strategy for deployment of Cisco Duo, I let our IT work on it, but we were able to roll it out easily, probably in around two or three days, we were done with our deployment.
What was our ROI?
The biggest return on investment for us when using this platform is the reduced time for us to give support, plus the confidence that we have, knowing that all our authentications or logins are secured.
What's my experience with pricing, setup cost, and licensing?
My experience with the pricing, the setup costs, and the licensing of the solution is quick and easy. There isn't much of an issue there. Even when we resell this to our customers, they're satisfied with it. The pricing is acceptable to them.
What other advice do I have?
My experience with Duo's strong security authentication system has been very easy to use. The process to log into our systems using Cisco Duo is just a two-step process for us, making it much easier to access these systems.
I evaluate the benefit of having a complete passwordless environment in my company through the convenience and ease of use of these devices or Cisco Duo into our devices and applications. I have encountered no challenges with Cisco Duo so far. It gave our IT no issues or problems.
Regarding the feature called Advanced Identity Threat Detection and Response in Cisco Duo, we haven't used it yet. My impression of Cisco Identity and Intelligence capability to detect and respond to identity-based risks effectively is that Cisco has been at the forefront for security. They have lots of data information especially with the network, wherein most of our customers are using Cisco. They get all the intelligence from there.
I have not yet used Duo's Conversational AI Interface for admin tasks. Regarding whether there could be more in the AI area in Cisco Duo, not really at this point. In our use case, we're not yet ready for that.
I would rate Cisco Duo around 8 or 9 out of 10.

Starts quickly with quick deployment but needs more support for older applications
Pros and Cons
- "Cisco Duo is quick to deploy and easy to start."
- "Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches."
What is our primary use case?
What is most valuable?
Cisco Duo is quick to deploy and easy to start. A valuable feature of the solution is its hybrid structure, which involves proxy agents running on-premises while other services are on the cloud. This setup makes it scalable, as the deployment section is in the cloud, allowing the installation of agents according to needs.
What needs improvement?
Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches.
For how long have I used the solution?
I have experience working with Cisco Duo for approximately two years.
What do I think about the stability of the solution?
I find Cisco Duo to be quite stable. I would rate its stability around eight to ten.
What do I think about the scalability of the solution?
I believe Cisco Duo is very scalable because it is cloud-based. It allows for the installation of multiple agents as needed, making it highly scalable.
How are customer service and support?
I find Cisco's technical support to be good but not excellent. I would rate it at eight out of ten.
How would you rate customer service and support?
Positive
How was the initial setup?
Deploying Cisco Duo takes a few hours. The deployment section is cloud-based. After installing the agent and connecting, it can be operational within a few hours.
What was our ROI?
I think Cisco Duo offers a good return on investment for startups, newer organizations, or those utilizing cloud-based applications. However, for very large organizations with numerous use cases or older applications, the ROI may be less favorable due to its lack of customization.
What's my experience with pricing, setup cost, and licensing?
I find the pricing of Cisco Duo to be reasonable.
What other advice do I have?
Cisco Duo is not very customizable but is suitable for newer or smaller organizations. For older or larger organizations, the ROI might be less due to the lack of customization. Overall, I would rate the solution seven out of ten.

Strengthened secure remote access through reliable multi-factor authentication
Pros and Cons
- "The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."
- "With Cisco Duo, you have to do that, and customers complain about that process. At some point, you need to be technically savvy to understand how to use Cisco Duo."
What is our primary use case?
I use Cisco Duo for multi-factor authentication, remote access, and remote access authentication. I use Cisco Duo primarily for the multi-factor authenticator for remote access.
What is most valuable?
Cisco Duo is beneficial for me in terms of security.
What needs improvement?
I don't have much detail about the integration of comprehensive identity security into the Duo IAM solution, but my complaint is that it's not as seamless as a product like Zscaler for remote access. It's not as seamless.
It's difficult for me to summarize the room for improvement as I'm on the enterprise network side, not really security. My response will be based on user experience, not detailed technical aspects of the network with respect to security. I use ZIA and Zscaler for remote access connection, and Zscaler is seamless. I don't need to do anything; it does the identification of my system. As far as my system is issued by the company, I don't need to do any multi-layer authentication. It authenticates seamlessly. With Cisco Duo, you have to do that, and customers complain about that process. At some point, you need to be technically savvy to understand how to use Cisco Duo.
For how long have I used the solution?
I have been using Cisco Duo for two or three years.
What do I think about the stability of the solution?
I've heard customers complain about latency in network usage.
What do I think about the scalability of the solution?
Cisco Duo is very scalable.
How are customer service and support?
I would rate the technical support of the product as a nine out of ten.
How would you rate customer service and support?
Positive
How was the initial setup?
The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage.
What was our ROI?
I do not track any ROI or return on investment.
What's my experience with pricing, setup cost, and licensing?
I think Cisco Duo is quite affordable; it's not really so expensive.
Which other solutions did I evaluate?
The major difference between Zscaler and Cisco is that for Zscaler, there's a component called ZIA that has a Zero Trust aspect. The identity comes with the system issued, so you don't need any multi-factor authenticator per se. Your identity is matched back end to know that you are the one, and you don't need to do another level of multi-factor authentication, which users complain of being cumbersome.
I use ZIA and Zscaler for remote access connection, and Zscaler is seamless.
What other advice do I have?
I am still working with Cisco products, and I still have the same portfolio. I don't work with the Cisco Secure Access product as I'm more focused on the enterprise infrastructure of routers, switches, SD-WAN, and data center. However, it's part of what I do, though not much of a call with respect to security, but it's something I'm interested in. I need to know what it does and if I can propose it to my clients.
I know Cisco Duo and have used it. It's not really a feature I handle regarding Cisco Duo's unified identity intelligence facilitating the understanding of user behavior. The security team handles that, and I don't have much visibility; it's purely transparent to me. However, I've heard them talk about it, and it really helps them to understand user behavior, mobility, and what they do on the network.
I would rate this review an overall eight out of ten.

Provides secure remote access with detailed user insights and seamless two-factor authentication integration
What is our primary use case?
One year ago, I deployed Cisco Duo for one of my clients at my previous company because we are a Cisco Gold Partner company. My client wanted to deploy Cisco Duo on their remote access VPN. They have a Cisco FTD firewall, and mostly users join on weekends through Cisco AnyConnect. My client requested 2FA for these users, so I deployed the solution.
A few months ago, I worked on Upwork where one of my clients approached me and asked if I could install Cisco Duo for their small cybersecurity company. This presented a good opportunity for me because I am in Pakistan, and my client is in the USA.
What is most valuable?
Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain. You can review the logs, including the public IP that the user uses, which country the user is in, and the city where the user is located. Everything is perfect in the logs. One tab shows that a user, for example Hasnain, is connected through remote access VPN and is using a specific public IP from a particular city in a specific country.
Cisco Duo offers a great logging solution in a Cisco environment. Additionally, Cisco Duo integrates easily with single sign-on apps, and I have used it on the Cisco ISE side because you can add the Cisco Duo address to your ISE and create the same user in both Cisco Duo and Cisco ISE. This makes it easy to manage, as Cisco ISE directly sends requests to Cisco Duo to verify, and the user logs in with a push notification or SMS code.
I am using many features in Cisco Duo, including logging in to Cisco ISE, sending requests when I log in to Cisco FTD through Cisco Duo, and checking 2FA on Cisco AnyConnect. Additionally, I have installed Cisco Duo app on my Windows-based machine, which checks for 2FA notifications every time I reboot the system or press Windows + L. This sends notifications to the cloud to check the username, and it also provides features that ensure the Windows Firewall is always enabled and verify that sensitive data partitions are encrypted. Moreover, it checks that antivirus is properly installed on the system. I also integrate my app within my company and have implemented single sign-on services through Cisco Duo, which is outstanding.
What needs improvement?
Cisco Duo could improve by considering feedback on features or requests for future releases.
When I worked on Cisco Duo, I encountered a limitation that I want to discuss. When a user logs in on a Windows machine using a Microsoft account, it is easy because you install the installer on your system and generate a code to enroll in Cisco Duo app. However, when I installed the package on the system, the user who was already added on Cisco Duo mobile app faced an issue. When I restarted the system, the screen turned black, and the user got stuck because we could not enter the username and password. After reading Cisco documentation, I learned that they do not support Hotmail addresses. This caused a problem since the user was using a Hotmail account. My client was very understanding about it, but I felt I failed to deploy Cisco Duo effectively. There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems.
The two main limitations on Cisco Duo are first, the requirement to install the installer on my server, and second, that Cisco does not support Hotmail accounts. I regret this limitation due to Cisco not supporting Microsoft accounts.
For how long have I used the solution?
I have been using Cisco Duo in my career for one year.
What do I think about the scalability of the solution?
Cisco Duo provides scalability and smooth integration with some applications.
How are customer service and support?
I have contacted Cisco customer support, which is highly remarkable. I open cases with Cisco regularly, and they provide prompt support for any case. Although I did not open any cases on Cisco Duo specifically, I have worked with many Cisco devices in my current network. Cisco support is notably above average; few companies match Cisco's technical and customer support capabilities when you are stuck on technical or pricing issues.
How would you rate customer service and support?
Positive
What's my experience with pricing, setup cost, and licensing?
Regarding the pricing for Cisco Duo, I find that Cisco is always costly. In my current network, I work in a financial institute where we use 2FA for Fortinet, which is easy to deploy but not scalable. Implementing Cisco Duo is more complicated, but when you integrate the solution fully, Cisco provides a very comfortable experience. The pricing comparison shows a great margin as Cisco is costly, while Fortinet is less expensive.
Which other solutions did I evaluate?
I use Fortinet, which you can ask me about as an alternative two-factor authentication solution.
What other advice do I have?
If you have any questions, you can ask me. I give this review a rating of 8.5 out of 10.
Which deployment model are you using for this solution?
On-premises
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

How are customer service and support?
I would rate their technical support a seven out of ten based on how they respond to issues.
How would you rate customer service and support?
Neutral
What was our ROI?
There is certainly ROI with Cisco Duo, assuming that you can get the other MFA type products uninstalled, and customers truly understand why they purchased Cisco Duo in the first place.
What's my experience with pricing, setup cost, and licensing?
From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations.
Which other solutions did I evaluate?
We did not consider many other solutions before Cisco Duo. I am biased towards Cisco because I came from Cisco, so I am more familiar with it.
What other advice do I have?
The benefit of having a complete passwordless environment is more of a conversation that we have with our clients. There is ease of use. We focus on what outcomes they are trying to achieve with the different personas they're using and the security protection in their workplace. There aren't any disadvantages to the passwordless environment, but it all boils down to what our customers are saying about the product that we sell to them. I haven't heard anything negative about Cisco Duo.
I would rate Cisco Duo overall an eight out of ten.
