My main use cases with Cisco Duo involve managing access. I've integrated it into my platform so that customers can connect using Cisco Duo. It manages all the users connecting on my platform and provides SAML integration so they can use their Cisco Duo account credentials to connect.

The feature I appreciate most about Cisco Duo is the ease of integration with my platform. It's straightforward with all the APIs they have to integrate with my platform. After that, I just put a Cisco Duo button on my login page, and then people can use their credentials. The integration is what I value the most.

Cisco Duo benefits my organization by making it easy for me to reach out to customers using Cisco Duo so they can integrate on my platform using their credentials. They don't have to change the way they connect, and it makes the whole experience seamless. That's why it's truly beneficial for my organization.

In Cisco Duo, what could be improved is having more features. We are using a front-end broker because the integration was something we struggled with. I would suggest releasing some API endpoints so we can have additional integration options beyond the basic one we used to have.

I have been using Cisco Duo for four years.

I assess the stability and reliability of Cisco Duo as having some slowness at certain points, but it's not really an issue. Overall, the performance is good.

I didn't have to use customer service regarding Cisco Duo.

The experience of deploying Cisco Duo was straightforward and easy.

I can say that I've seen a return on investment from having Cisco Duo.

Cisco Duo has provided a return on investment by integrating and increasing my reach to people and customers using Cisco Duo. It has had an impact on my revenue because I was able to integrate more customers. There is a clear ROI to this.

My experience with the pricing, setup cost, and licensing for Cisco Duo is that I've been working with Cisco for a long time, so it's straightforward. Pricing is per user, so it's easy to understand.

Before adopting Cisco Duo, I considered other solutions. I've worked extensively with Azure AD and Okta. However, because Cisco Duo is a Cisco product, it makes sense for me to integrate with it.

I am not using Identity Intelligence in Cisco Duo.

I haven't noticed an increase in phishing attacks in my organization recently.

I haven't implemented Cisco Duo end-to-end phishing resistance with proximity verification, though I may consider it if needed. I wasn't aware of the feature until now.

I have deployed Cisco Duo Directory to manage user identity.

I use a front-end broker with Cisco Duo that manages all the IDPs for my platform. It integrates with Cisco Duo and different SAML providers.

I would not say that Cisco Duo helped reduce the overall authentication-related costs, but it definitely helped specifically for managing those customers.

I did not discover any feature in Cisco Duo that I didn't think I would use initially and later discovered along the way. I believe we are knowledgeable about all these SAML providers, so we knew what we wanted to leverage.

I would rate this review as an eight out of ten.

My main use case with Cisco Duo is for two-factor authentication. I need Cisco Duo authentication in my company because I have no different option to use a different solution not related to Cisco due to a limitation of a product like Cisco ISE that will not be able to use a different mechanism than Cisco Duo authenticator. I have to use Cisco Duo authentication to have two-factor authentication and fulfill security requirements in the company.

The feature I like the most about Cisco Duo is two-factor authentication. Cisco Duo helps me to defend against phishing attacks and provides security for my organization.

I really have no idea how Cisco Duo can be improved. I do not see any features that I would like to have that are not currently implemented.

I have been using Cisco Duo for about half a year.

I have not noticed any stability or reliability issues such as downtime or crashes.

I think Cisco Duo will scale with the growing needs of the organization. It will be growing because every company and every regulation requires two-factor authentication, and we have to use it by one vendor or another. I think a solution such as that will be growing in the future.

I mainly used the Microsoft solution because we have merged a lot of products with Microsoft, and using DevOps, Azure, and other services is naturally how we use Microsoft authentication for many things. However, if we cannot do it in some scope, we have to find out how to do it in a specific section.

With the deployment of Cisco Duo, I can do it with instructions. I am not an expert, but I am something between beginner and intermediate.

I cannot say that I have seen a return on investment from having Cisco Duo. I have experienced only a security benefit.

My experience with the pricing and licensing and setup costs is that I think it is fair because licensing depends on the user that uses it and consumes those tokens.

I had to reduce a lot of Microsoft Azure Authenticator, but for some reason, it is not supported in some products of Cisco. We have to divide it so that Cisco Duo also covers those needs.

I do not use Cisco Identity Intelligence. I have not noticed any increase in phishing attacks recently, but I work in a financial company where the security is critical. If something can happen one time per 25 years, it is very risky and has to be mitigated somehow. I have implemented Cisco Duo end-to-end phishing resistance with proximity verification for both. I did deploy Cisco Duo Directory to manage the user identity and am using it as a standalone identity provider. I do not think I discovered any new functionalities that I did not think of in the beginning. I did not really face any challenges doing that. I would rate this review a 10 out of 10.

My main use cases for Cisco Duo are two-factor authentication and single sign-on for different solutions.

The feature I like the most about Cisco Duo is the dashboard to have everything in one single place and manage multiple customers and multiple tenants simultaneously.

Cisco Duo benefits my organization because we do not have too many logins since everything is in one place and we can use Cisco Duo for VPN, applications, and cloud solutions. This is a main benefit and the core purpose of the product that we are utilizing.

I think Cisco Duo can be improved. I found the onboarding was very difficult, even for engineers who have been using similar solutions before. For our specific implementation, we needed to have multiple groups, multiple companies, and multiple third parties, and I felt that the examples and material provided were insufficiently detailed. The onboarding videos, materials, how-to guides, and documentation should be improved dramatically.

I have been using Cisco Duo for approximately three years.

I did not notice any downtime or crashes with Cisco Duo. We focused on making modifications and changes only during maintenance windows, and afterwards in production, we did not have any downtime.

Cisco Duo's scalability works well with the growth of our company and does not seem to have a limit. We could add as many users and as many sites as needed, so scalability is not an issue.

Before implementing Cisco Duo for this particular customer, I did not consider another solution. However, for other customers, we also use some open-source solutions and cloud providers, which unfortunately seem to be winning over Cisco Duo.

I cannot say I have seen a clear return on investment. However, as I was only the integrator, it is difficult for me to make an estimation on the customer's actual ROI. That said, considering that they did not have any more attacks, it is probably positive, but I am not able to fully evaluate that.

My experience with pricing, setup cost, and licensing for Cisco Duo is that it is not an expensive product. The issue was that we had a customer migrate away because they moved to one of the cloud providers for identity management as well. The difference in cost to upgrade to directory services on that platform was cheaper than having Cisco Duo. However, generally, if a customer is not tied to a specific cloud vendor, then the pricing is acceptable.

I do not recall seeing Cisco Identity Intelligence or using it.

I have noticed an increase in phishing attacks recently, and this was exactly the reason one of our customers asked us to implement Cisco Duo because they were attacked before and lost quite a bit of money. After that incident, we deployed Cisco Duo for them. While using Cisco Duo, we did not have any issues regarding other attacks.

When implementing Cisco Duo, I implemented end-to-end phishing resistance with the proximity verification as the full solution.

I deployed Cisco Duo Directory to manage user identity.

I am using it as an identity broker because we were not integrating to the customer's Active Directory. It was actually functioning as an identity proxy rather than as a directory per se.

The organization's overall cost for authentication was higher, but the indirect cost of being attacked and losing data is significantly greater.

I discovered new benefits after initial implementation when we started with basic VPN authentication and then developed many other flows based on that. We learned that there were not enough examples or documentation available so we could start from the beginning knowing everything about the product.

The deployment experience was complicated as it was a trial and error process. We had multiple existing systems, and for each system we wanted to integrate with Cisco Duo, the approach was different. One was connecting directly, one was using the API, one was using SAML, and one was using directory services, making the process quite challenging.

I would rate this review an eight out of ten.

Cisco Duo is used primarily for access management, zero trust architecture, and identity management, with MFA serving as the main feature.

My favorite feature in Cisco Duo is the remote app access.

The remote app access feature helps our company by providing strong MFA protection in the event of password and username leakage from any employee, ensuring that we can protect our applications more effectively. Cisco Duo integrates smoothly with our environment, avoiding challenges that might arise with third-party products, making it an ideal solution given that we work with Cisco for support and AI technology.

Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications.

We began using Cisco Duo in 2024 as a demo, and after 30 days of evaluation, we transitioned to live production for almost four applications. We plan to increase to six applications in 2025 and ultimately expand to 12 or 16 applications by 2026.

The stability and reliability of Cisco Duo depend on the environment and Cisco's cloud infrastructure, which is beneficial since Cisco does not compete with your applications but rather secures them.

I believe there is no need for scalability concerns with Cisco Duo because it is designed to handle future expansions from the beginning.

My experience with Cisco Duo's customer service and technical support has been perfect, as I had an interaction that went very well. I would rate the customer service and technical support from Cisco Duo a ten.

Before choosing Cisco Duo, we were using a legacy VPN and did not publish applications that were not critical to the public, utilizing them only on a remote site.

The deployment process of Cisco Duo is not straightforward; you need some knowledge of best practices because you are facing attackers, and it is better to let professionals handle it, especially when working in a critical environment.

We did consider other solutions before choosing Cisco Duo and took several products for demos, ultimately deciding on Cisco Duo.

The biggest return on investment for us when using Cisco Duo includes disabling the public IP in our environment, which is a key goal for us.

Looking back at the initial investment in Cisco Duo, I find that the choice has paid off for our company, especially considering the difficulties of transitioning from traditional and legacy technology, and I hope we will continue to realize its value.

I am not certain if Cisco Duo has reduced our overall authentication-related costs, but it has helped us manage and keep everything under control, which is our priority for safety.

The decision to choose Cisco Duo is based on the many features it offers that we did not find in other applications, and since we were already using Cisco for our other needs, it made sense not to switch to a competitor.

Recently, we have noticed a heavy increase in phishing attacks targeting products not protected by Cisco Duo that are still published on the public network, as attackers are trying to obtain data.

I believe this significant spike in phishing attacks is due to AI bots, which are easier to acquire, as the cost of using them is reduced, making the attacks more commonplace despite the number of human attackers remaining the same or even decreasing.

We have deployed Cisco Duo Directory to manage user identities. We are using Cisco Duo Directory today as a standalone identity provider, connected with Microsoft Azure SAML as an identity broker.

We have implemented Cisco Duo's end-to-end phishing resistance with capabilities such as proximity verification. Our implementation of Cisco Duo strengthens our company's ability to defend against modern phishing and identity-based attacks through compliance with various benchmarks, offering multiple defense points, and isolating applications to prevent the use of shared resources among them, even ensuring isolation at the DNS system level via Umbrella.

We hope to use Cisco Identity Intelligence in the future, but we have not implemented it yet.

My advice to other companies considering Cisco Duo is to purchase it, as it really addresses security concerns and transforms the way you feel about security. My overall rating for this review is nine.

My main use case for Cisco Duo is to protect the OT environment from remote access.

The feature I like the most about Cisco Duo is that I can choose which device I want to sign in.

It is valuable for me that I can choose because not all people have a corporate phone, so they can use their personal phone for access or different methods for performing second-factor authentication.

I can say that it is difficult to measure the direct return on investment, but what I can say is that we are safer and feel more comfortable having this security implemented than before.

I cannot think of any improvements for Cisco Duo at this time.

I have been using Cisco Duo for approximately half a year.

I do not have problems with stability or reliability. Being a cloud solution, I think it is difficult to have problems, and we also use Umbrella with Cisco, which is very reliable and has high availability.

The solution is scalable for our growth.

We used Okta sometime before Cisco Duo.

We used Okta in a different environment, and we finished our license; we were not seeing the need to keep using Okta. For this new environment, we chose Cisco because we wanted to have a homogeneous solution, and our colleagues in other countries were happy, so it was easy for us to choose.

The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers. We also had concerns about opening the mandatory connection to a specific URL and port from our OT environment.

My experience with the pricing, setup costs, and licensing is that the price is acceptable because the license is by user.

We were considering different solutions, but we are a global company, and in another place in our company, they were using Cisco Duo, so it was our first option because we want to have a homogeneous scenario.

I do not think I am using Cisco Identity Intelligence.

I have not seen an increase in phishing attacks recently; I think they are more or less constant, but not increasing, particularly in the last three or four months.

We have seen the number of phishing attacks increase every year, but I do not know if that surprises us; we are accustomed to having this type of risk.

I think I have deployed Duo Directory to manage the user identities.

I think I used it as an identity broker in front of the IDPs.

My review rating for Cisco Duo is 8.

The main use case for Cisco Duo is MFA, which means multifactor authentication using the app and using keys like YubiKeys for various devices, such as RDP and remote access, but I would say remote access is the most prominent use case.

Right now, the feature I appreciate most about Cisco Duo is the Duo Directory, which is exciting because it became an IDP.

It is exciting that with Cisco Duo, I can offload guest users and contractors to Duo, so they do not have to exist in the customer environment from their AD, which is a nice way to accommodate guests and contractors needing access to applications.

I express how I appreciate Cisco Identity Intelligence to customers using the Duo Advantage license and always try to push them to at least take a look because it is essentially free with the Duo product.

I have multiple MFA vendors in our portfolio, and I try to position Cisco Duo because I think it is a really good product, but we also try to position other solutions depending on what the customer wants and where they think we can go together.

I deployed Duo Directory to manage user identities, and I think it is great because it is never a standalone provider; it always acts as an additional provider or broker functionality to be the front door and decide to go this way or go to the other IDP.

Once Cisco Duo is set up and running, it just keeps running.

I think Cisco Duo can be improved with more YubiKey support with all applications, especially for Windows login.

I have been using Cisco Duo for three to four years, since the beginning of 2020.

I did not notice any problem with stability and reliability; it was always available with not much downtime needed.

Sometimes if I have problems, I obviously have to create a TAC case to ask for help, but most of the time, I would say it is very stable.

I think Cisco Duo is scalable for organizational growth, as we have some customers using it who then onboarded new users and even bought companies and onboarded them; it is highly flexible and I did not feel any slowdown anywhere.

The experience of deploying Cisco Duo is great; it is fast and not too complex in my opinion, as you can integrate basically anything into Duo, so I would say the experience is overall very great as an administrator.

I think Cisco Duo helped reduce the overall authentication-related cost for the company indirectly, as there is less work to do for the admins, because once it is set up, users understand the app, know how to use it, and rarely have problems, so if new devices need registering, they can do it themselves, depending on the setup.

The pricing for Cisco Duo is kind of okay, but most of the time, your competitor is someone like Microsoft who gives it out for free with their offering, making it tough to argue with customers why they should spend additional dollars to also get Duo to improve their setup, but I think the pricing is fair.

I am mostly part of the deployment and with the customers; I am not on the operational side of things, so I cannot really share about phishing attacks, but I mean, Cisco Duo allows phishing-resistant MFA, which is why I try to push my customers to use it, so I would argue, hopefully not.

That is why I try to push my customers to actually use proximity verification and use passkeys to strengthen security, which was mentioned in my previous answer.

I think there is a return on investment for the support team, where they can help validate customer requests and also through self-service portals, but I do not have any numbers regarding return on investment.

I would give Cisco Duo as a solution a rating of 10 because it is great.

Cisco Duo primarily secures our environment.

I appreciate the features that Cisco Duo offers. Cisco Duo's team sent us some questions, for example, about the feature called Identity Intelligence. I have tried using the Identity Intelligence feature and have been working with it. I can confidently say that Identity Intelligence has improved my visibility into identity risk and has helped me make defenses against identity-based threats better.

The main issue with Cisco Duo is dependency. For example, it verifies the subscription with features Duo Push, OTP code, and phone dependency. If you lose or break your phone, users without smartphones will face connectivity issues. There is also integration challenges, support for legacy systems and cloud connectivity, management overhead, and the system can be bypassed by phishing techniques.

To improve these issues, users should be required to confirm a number to approve authentication requests. This would enable disabling auto push and then enable trust-based authentication with new device detection, new location detection, and VPN detection.

Additionally, Cisco Duo is subscription-based depending on the number of users and has a dependency on mobile devices for advanced features. The cost will become expensive for large user accounts. The system requires approve push and either OTP, with push deployments through Duo mobile applications. There is limited offline support, it requires internet connectivity and cloud dependency. Internet outages can cause authentication issues affecting VPN, Windows login, and cloud applications.

I have been using Cisco Duo in my career for three years.

I do see instances of lagging, crashing, or downtime. We used to experience downtime, for example, during code upgradations and OS upgrades on the server, switches, and firewalls. We try to mitigate it, but we need to implement upgrades without downtime. Sometimes the device will not come up after reboot, which can cause downtime.

Cisco Duo performs well regarding scalability. The scalability depends mostly on the number of users. The system has good scalability and can handle more users, more logins, and more locations without performance issues. This depends on the cloud-based, globally distributed infrastructure with no dependency on on-premises services. It can scale from 10 users up to thousands and hundreds of users. The system also has load balancing, high availability, and failover capabilities. A small office can support up to 50 users, while a large office can support more than 10,000 users.

I have contacted customer support regarding Cisco Duo for assistance. The quality and speed of support depend on various factors. For example, when we receive any ticket, we need to assign it to ourselves first and then depend upon the SLA to work on the ticket. We need to resolve it within the SLA timeframe.

Regarding Proximity Verification feature, I have seen it in action last year.

Cisco Duo's initial deployment is easy. We need to have a mobile application and need to install it for users on VPN, servers, clouds, cloud applications, and for admins and passwords. We need to have a security policy required and identity source such as LDAP, local users, Active Directory, and Azure AD. We need to have VPN devices for servers and firewalls with HTTP 443 port number. We need to have web applications and cloud applications, and Windows login. We need to have end-user devices for MFA, such as a smartphone and SMS. We need to have synchronization for security policy purposes, licensing, and many other components.

Regarding the pricing for Cisco Duo, it is somewhat expensive. Cisco Duo costs depend on the technology. Up to 10 users, it is free. Premium versions go for dollars, such as $10 per user per account. As the number of members increases, the cost increases. It is very useful to have for multi-factor authentication.

I would rate the return on investment at an 8 or a 9.

I have noticed an increase in phishing attacks in my organization recently. There has been a significant spike in the number of attacks, and they feel more sophisticated, which makes them more difficult to deal with. We used to get phishing attacks through our emails, SMS, WhatsApp, and fake website links. The domain may show a hyphen, for example, Microsoft hyphen login, and attackers will try to send a link. If you click on that link, all our data will be hijacked. We need to protect our devices and environment and should not click any unknown links. That is why we need to enter MFA with valid credentials.

Alternatives to Cisco Duo that we have been using in our organization include third-party applications. We can use Okta and Microsoft SSO, Microsoft Azure MFA, Rublon MFA, Twilio, and PingID from Ping Identity. There is also Secure Authentication and RSA SecurID in the market. There are many third-party alternatives available.

The main issue with Cisco Duo is dependency. For example, it verifies the subscription with features Duo Push, OTP code, and phone dependency. If you lose or break your phone, users without smartphones will face connectivity issues. There is also integration challenges, support for legacy systems and cloud connectivity, management overhead, and the system can be bypassed by phishing techniques.

To improve these issues, users should be required to confirm a number to approve authentication requests. This would enable disabling auto push and then enable trust-based authentication with new device detection, new location detection, and VPN detection.

Additionally, Cisco Duo is subscription-based depending on the number of users and has a dependency on mobile devices for advanced features. The cost will become expensive for large user accounts. The system requires approve push and either OTP, with push deployments through Duo mobile applications. There is limited offline support, it requires internet connectivity and cloud dependency. Internet outages can cause authentication issues affecting VPN, Windows login, and cloud applications.

My overall review rating for Cisco Duo is 8.

My main use case for Cisco Duo is as a two-factor authentication. A quick specific example of how I use Cisco Duo is through 2FA. Everything is fine with my main use case.

In my opinion, the best features Cisco Duo offers include its 2FA authentication, which is very good. Everything is perfect about the features; it is very easy to use, and the integration with other systems is very good.

Cisco Duo has positively impacted my organization, and I have noticed specific improvements since using it. The improvements I have noticed include making security very good and increasing our overall security.

I believe Cisco Duo can be improved, but I think the current state is sufficient. I don't really wish for any specific changes regarding needed improvements.

I have been working in my current field as an infrastructure engineer for approximately 15 years.

Cisco Duo is very stable.

Regarding Cisco Duo's scalability, it meets our requirements.

Customer support for Cisco Duo is very good. I would rate the customer support as a nine on a scale of 1 to 10.

I have not used a different solution before Cisco Duo, as it was the first solution I implemented.

My experience with pricing, setup cost, and licensing for Cisco Duo is that it's not getting worse; it's better now.

On a scale of 1 to 10, I would rate Cisco Duo as a nine because it's a very good solution.

Looking back at my initial investment in Cisco Duo versus the total value it has delivered over time, I have seen a return on investment.

Before choosing Cisco Duo, we had IPV as an option.

My advice to others looking into using Cisco Duo is to recommend they use Cisco Duo. My company does not have a business relationship with this vendor other than being a customer.

I have not implemented Duo's end-to-end phishing resistance, and we don't have capabilities such as proximity verification. I still need to check about using Cisco Identity Intelligence. I have noticed an increase in phishing attacks in my organization recently; the attacks are getting more frequent, which is why we improved the security for 2FA.

I give Cisco Duo an overall review rating of 9.

Our main use cases for Cisco Duo are to support all employees that need to connect remotely, which is the primary case we're using, and we also use it for some technical parts, like connecting our Meraki to Cisco Duo for the IT.

What I appreciate most about Cisco Duo is how simple it is to use; you connect it to the email address and phone number, and you are able to push everything to the client. You can watch the log for a quick response to see if it's working or not, and check what went wrong in the log during the morning or something, and even push something to everyone if needed, so there are many valuable aspects which is very good.

The benefits of Cisco Duo for my company include how easy and simple it is to use; Cisco Duo is so easy to maintain and everything grows quickly with the number of users you add into it. You can even add new applications for verification, and it's policy in our company to have two-factor authentication, which we use in combination with that.

I cannot think of a specific feature that should be focused on for improvement, but perhaps addressing the trouble we have when people are changing phones would help. When a new phone is obtained, and Cisco Duo needs to be installed, it is easy to go into Cisco Duo and find the user to push verification, so perhaps doing this through Active Directory could make it easier, but that also raises questions about security.

I have been using Cisco Duo for approximately four years.

I would describe the stability and reliability of Cisco Duo as excellent because we almost never have troubles with it; the issues we face are with other systems, not Cisco Duo.

Cisco Duo scales very well with the growing needs of my company; during COVID, when we had a higher number of users, there were no problems at all.

I would describe my experience with the customer service and technical support of Cisco Duo as excellent service, and I could totally recommend using Cisco Duo, so it's 100%.

I would rate the customer service and technical support of Cisco Duo a 10, for sure.

Before choosing Cisco Duo, we considered Authenticator, which is similar, but I found Cisco Duo easier to implement because we have everything from Cisco, including firewalls and other essential technologies, making it the best choice for our environment.

The deployment process for Cisco Duo is easygoing; I would say it's very easygoing.

I think it took about two days to implement Cisco Duo; as I mentioned, if you connect it to Active Directory, it's straightforward, especially the first time, as you pick everything up from Active Directory and only need to go into Cisco Duo later when people change phones or something similar, requiring verification to see how many users are pending or have not used it.

The biggest return on investment for me when using Cisco Duo is security; that's the main point.

Cisco Duo has helped my company reduce its overall authentication-related costs.

I cannot provide an approximate percentage of how much it has helped reduce because, as I mentioned, if people don't use it, they don't get access.

I think the pricing of Cisco Duo is fair because we hired a number of users during COVID when we had many people working remotely, and the costs increased; if I remember correctly, Cisco offered something during COVID that gave us a lower price, so I find the pricing fair.

We thought about Authenticator, and our choice ultimately was Cisco Duo.

My advice to other companies considering Cisco Duo is not to wait; start using it and implementing it. I would rate this review a 10.

I mainly help customers to setup Cisco Duo for multi-factor authentication.

Duo significantly increases phishing resistance for application access. So the main benefit is improved security.

Passwordless authentication - This is the future of secure access. By eliminating passwords entirely through FIDO2/WebAuthn, Duo removes the primary attack vector for credential theft while also simplifying the login experience for users.

Cisco Duo is technically excellent, but the main challenge is market positioning rather than product capability. Microsoft Authenticator comes bundled with Microsoft 365 at no additional cost, so many organizations default to that solution rather than purchasing Duo as a standalone product.

I have been using Cisco Duo for approximately one and a half years.

Cisco Duo is very stable. I have never experienced major outages or service disruptions. The product itself is reliable - any minor issues we've encountered were typically user configuration errors rather than platform problems.

The scalability is excellent. Being cloud-based, Duo handles any user count without infrastructure concerns. We've scaled it across multiple customers without performance issues.

I have no experience with their support - I have never encountered issues that required contacting Cisco. The product documentation and admin portal have been sufficient

Yes, I used Microsoft Authenticator but only as a end user. In my opinion, Duo is simpler and more intuitive. From an admin perspective, I can't give a review.

The initial setup is straightforward and fast. Duo's phased rollout approach shows they understand real-world deployment challenges. Overall, it's very easy to implement.

My company is a Cisco Duo reseller and partner, so we perform the deployments ourselves for our clients rather than using external integrators or consultants.

I don't have quantifiable ROI data. The value is primarily in risk mitigation - preventing phishing and credential theft. The cost of a single breach would far exceed the investment in Duo. I cannot speak to operational cost savings like reduced password reset tickets.

The pricing is fair and straightforward - per-user licensing makes budgeting simple. Setup is easy and intuitive. The licensing tiers are well-structured and easy to understand.

9 out of 10. Duo is technically excellent - stable, feature-rich, with outstanding passwordless capabilities and straightforward deployment.

My advice: Take advantage of the free tier (up to 10 users) and 30-day trial to test it in your environment.
