Cisco Duo Valuable Features
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter.
I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.
View full review »Cisco Duo is not doing anything that competitors are not doing. I have worked on Okta as well, and Microsoft Entra ID has really improved. The primary benefit of Cisco Duo is if you already have an extensive footprint of Cisco products, such as Cisco Secure Access, Cisco Secure Firewalls or Firepowers, or Cisco Umbrella deployments, then it becomes very easy to integrate these products together so they work hand-in-hand with deep integration.
Cisco Duo offers phishing resistant IAM and multifactor authentication (MFA), which relies on Cisco Talos Threat Intelligence sharing to enrich Cisco Duo with all threat feeds. This provides pinpoint accuracy to determine what is malware or malicious and what is safe.
Identity intelligence is analogous to what Okta or Entra ID does with conditional access. It gives you a complete view of whether a particular user who seems legitimate is actually supposed to get access to applications or not. You can control access and curtail access depending upon the behavior of a user.
MFA is mandatory, and there are multiple ways you can implement it. Phishing resistance is critical because even if a user's account has been compromised, the tool regularly tracks how that particular user accesses applications and where they do it from, creating a baseline. If there is a deviation, which would definitely be the case if the user or user identity is compromised, it asks for step-up authentication or curtails access to the application. This end-to-end phishing resistance feature definitely has an impact on the company's security posture.
View full review »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.

Cisco Duo
February 2026
Learn what your peers think about Cisco Duo. Get advice and tips from experienced pros sharing their opinions. Updated: February 2026.
883,089 professionals have used our research since 2012.
The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular.
There isn't a lot of training that goes on in school districts. Email is an easy way where many people give out their credentials, so the level of protection is something that we definitely need in a school district.
Cisco Duo's strong security authentication system has been easy when logging in, although the teachers don't appreciate it as much. We have it configured so users essentially just hit accept. If it sees any sort of built-in risk, then it steps up authentication. It's pretty easy. I appreciate it.
I've encountered advantages with Cisco Duo in that it has stopped significant pushback from teachers. It has prevented credential sharing and unauthorized access. We've seen a huge decrease since we've rolled it out across the entire district.
View full review »The feature I like the most about Cisco Duo is push notifications.
I find push notifications beneficial because they are easy, quick, and simple.
An example of how this feature benefits my organization is when last year, Cisco released an announcement that all distributors and partners need to use two-factor authentication for logging into CCW. We were setting up two-factor authentication, and we had two options. Cisco was giving us two options: Cisco Duo or Microsoft MFA. We chose Cisco Duo as a distributor. Everyone started to use Cisco Duo when they were logging in to CCW, and they liked it. After a while, Cisco released another announcement to extend the obligation of Cisco Duo usage for logging in, but most of the people did not stop using it. They liked it and they are still using it.
View full review »The Verified Duo Push feature is valuable. It gives an extra level of security beyond just the regular push. Before that came out, we had a few instances of people getting compromised, pushing the button because they thought it was something else they were doing, and it turned out to be an attacker compromising their account. We were able to enable that pretty much as soon as it went into production, which drastically cut down on any issues.
It's been pretty easy. There haven't been too many challenges. It does what it says it does. It's easy. It's straightforward. It's not a hard process to do anything with it. Even though we don't take a lot of advantage of it, there are always new features that are coming out. It shows that Cisco puts time, effort, and development into it.
The feature of Cisco Duo that I prefer the most is centralized authentication for both TACACS and RADIUS.
My ability to decrease time while using Cisco Duo varies. We don't change up people frequently, but one person would take me up to an hour out of my day to onboard or offboard. If we onboard 10 people I could spend my entire day giving access.
View full review »I find the MFA, multifactor authentication, and Universal Prompt most useful in Cisco Duo. This is a SAML connection. The trusted endpoint and Windows Logon, MFA with Windows Logon, and RDP connection are valuable features. Cisco Duo can be integrated with many third-party vendors and third-party applications.
The main reason my customers started using Cisco Duo is because they need to have a multifactor authentication application to secure their application.
The biggest benefit of Cisco Duo for my customers is the license because they count licenses for the user. One user can use any application. If we buy a 100 or 200 user license, one user can use many applications integrated with Cisco Duo.
Passwordless is a good feature for customers to use Cisco Duo without prompting for the password. They can type the email address, and they can access their application continually and faster than before.
The return on investment my customers see with Cisco Duo includes having the inventory of their mobile and computer. They have Cisco Duo to do the inventory for them, and the MFA helps protect their application.
View full review »You can do online and offline authentication. It benefits my organization by adding an additional layer of security and keeping us more secure, whether the person is corporately connected or out in the field.
The feature that my organization started using more recently in Cisco Duo is offline authentication. It has given us the evolution into offline abilities for when they are out in the field or traveling, and they are not connecting to a known network.
View full review »The most valuable feature of Cisco Duo is the MFA itself, and the integration is pretty straightforward. The documentation is good.
Cisco Duo helps improve a company through security, and we have the regulatory compliances we have to meet by having Cisco Duo's MFA enabled. With Cisco Duo, we get that checkbox filled.
View full review »What is good with Cisco Duo is I have to explain that it's not just an MFA because some customers already have an MFA in place. I can talk about other products from Microsoft or any other product, and they say, "We already have an MFA." So I have to explain to them that Cisco Duo is not just an MFA. With an MFA, you want to access something, and the MFA is going to check if you can enter, yes or no. It's not going to check your background or what you have. Cisco Duo is a pre-MFA and post-MFA. With Cisco Duo it's checking if you are allowed to submit a request to access this. If your company is just working with Windows and you are trying to access with a Mac, Cisco Duo is going to be able to say, "Why are you working with a Mac? It's not allowed," so you're not going to have a request. Or if you are, for example, working in Germany and you only have workers in Germany, and suddenly your IP address is in Spain, then I can explain to the customer, "Okay." The customer might say, "Okay, I have a request from Spain, but we don't have people working in Spain, even remotely. So we will block it directly." That's the good thing. It's comparable to when you want to go to a nightclub, they ask you if you are 18, but they also check it with your ID card and everything. It's the same with Cisco Duo. They do a complete check of you before you access.

The best features of Cisco Duo include easy integration. I could do a lot of things with Cisco Duo comprehensively. Multiple types of MFA are available, and the fact that it passed the certification with the Department of Defense gave Cisco Duo an A+.
I use Cisco Duo's Advanced Identity Threat Detection and Response feature, which includes all the necessary counterparts. It has the intelligence to detect threats, performs risk assessment, and then provides a score to determine whether someone is legitimately attempting to sign in.
This feature has been helpful because it validates while maintaining trust. The trust but verify design principle is fundamental. Cisco Duo includes the Zero Trust Architecture, where everything lists a privilege, and from there, Privileged Access Management applies. If you want to elevate someone and give them additional privileges, the system handles that process.
View full review »I think Cisco Duo's identity intelligence capabilities are effective as long as you give the right policies to them. Defining your own set of policies is crucial to successfully utilizing the product's advanced features.
The thing that I appreciate the most about Cisco Duo is the ease of setup. The implementation team does not have to spend more time on implementing or integrating the product. Their responsiveness is commendable, and they are easy to adapt to new trends in the market, which suits our business needs. The pricing of Cisco Duo is also quite reasonable compared to other products.
The Advanced Identity Threat Detection and Response feature is similar to what I explained regarding AI and identifying threats.
Windows Hello is a new feature Cisco Duo has started using recently. It allows a user to connect to the VPN and get access to applications without needing to re-enter passwords. Once a user is authenticated against the VPN in Cisco Duo, the Windows Hello feature allows immediate access to applications without requiring another password entry.

The features of Cisco Duo that I appreciate most include an administrator's ability to see an overall view of what types of devices users use, which helps identify risks from endpoints that might not be secure enough anymore, and you can see it in one single glance.
The benefit of this feature for my company is that it provides an easy view to see what users are doing, especially with the challenge of bring your own device. Many companies do not want to provide a company device but allow users a budget to buy what they need. If someone wants an expensive iPhone, they have to contribute some of their own money to fit it within their budget, which avoids extra costs for the company while still providing insight into what users are doing.
View full review »The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone. This has proven particularly beneficial for older users who historically struggled with other MFA solutions. Cisco Duo benefits the organization by fundamentally enhancing security.
View full review »One important benefit of using Cisco Duo solution is to ensure that the person using the VPN has their username, password, and mobile; they must approve or decline if they do not have their mobile. Another important benefit is managing users who have access to the VPN because sometimes there are users designed to have access, but the system administrator forgets to remove them, which we can effectively manage from the portal itself.
View full review »Cisco Duo's secure access for VPNs and remote users stands out as a valuable feature, as it integrates with Cisco AnyConnect and third-party firewalls and VPN solutions such as Palo Alto, FortiGate, and SonicWall, which is valuable for hybrid and remote work environments.
I use the unified identity intelligence in Cisco Duo to facilitate understanding user behavior, and this understanding helps my organization by providing a consistent and centralized identity for a user across all systems, applications, and other access methods, allowing a single identity for all systems and applications.
I use the end-to-end phishing resistance feature in Cisco Duo, which helps my security posture by securing the entire authentication journey, meaning that phishing attacks fail even if a user is tricked into entering credentials up to the final access.
View full review »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.
View full review »What I most appreciate about Cisco Duo is the ease of use.
The strong security authentication system has been easy while logging in. I just use the app.
The benefit of having a complete passwordless environment in our organization is that it's gotten people away from using the sticky note under their keyboard - which is a huge problem. It's also helped stop the sharing of passwords. You'll have somebody that's out one day and somebody will just sit down at their computer and use that person's password. We can now stop a lot of that stuff.
The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up. The experience with Duo's strong security authentication system has been easy when logging in.
View full review »The general usability and visual interface are valuable to me. It is not significantly different from other tools, but it is usable. It is suitable for a technical person who has an understanding of these tools or software and finds it usable and understandable.
It provides the possibility to get employees directly started with their jobs or schooling for new projects. For this, what is important is the time between registration and account access and whether there is a general problem or minor questions about the main reason. However, there are no strong problems.

What I appreciate most about Cisco Duo is the fact that I can input the code instead of acknowledging it through the app. If I'm overseas, I can simply input the code. This benefits my company by meeting and satisfying the security requirements imposed on the network by the security team.
My impression of Cisco's identity intelligence capability to detect and respond to identity-based risks effectively is that it's a great product.
The phone is the preferred location for Cisco Duo installation, not a separate key fob, as SecureID used to do. That is the preferred method, so I don't see any other options. I have never gone into Cisco Insider.

I appreciate the secured push feature of Cisco Duo because you have to choose a number.
I value this feature because it is a security feature that enhances the security of your users, and if you also have geolocation for verified push, that would be even better.
It benefits our company as well as our customers because it is more secure. You can have geolocation or know which network the users are on, so if they do not have a push when they are in the company, but if they are on holidays or traveling somewhere, they have a push verified login, which is much more secure.

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.

Jernej Zevnik
Manager, Customer Success at a tech services company with 201-500 employees
The simplicity and the number of integrations available in Cisco Duo are the two aspects I appreciate the most.
Cisco Duo is remarkably easy to use. You log in, receive a push notification on the Cisco Duo app, and simply confirm it to gain access. The number of integrations available is exceptional as well. I believe no other MFA service has as many integrations available, and for those who prefer not to use the app, an SMS fallback remains available.
The benefits of such simplicity in Cisco Duo are significant. Employees spend considerably less time logging in and approving logins. They do not grow tired of the multi-factor push notifications because it is easy, fast, and not repetitive, so we do not experience much attrition from it.
Cisco Duo has provided substantial value, primarily in saved time, but also in low cost because administrators do not have a significant workload with Cisco Duo. It simply works, and I believe it has been a great investment for our company.
View full review »Cisco Duo is very user-friendly. You do not need to struggle, and you do not need to teach non-technical users or executives how to use it. If you miss a device or change your phone or handheld devices, you can still reactivate on your new device very easily. It is very user-convenient, and there are many methodologies available. You can get SMS alerts, web plug-ins, and push notifications. It is available for both Android and iOS.
As long as we are clearing the audits, that confirms that we are secure enough. We have been able to convince our security auditors that we are compliant with all the laws, at least from an MFA standpoint, regarding the return on investment from using Cisco Duo.
View full review »The feature of Cisco Duo that I appreciate most is the push notifications. They are great. I'm glad that they can be accessed from my watch personally. Many of our staff use the phone calls so they can just answer and press one without needing to pull out their mobile phone and get the code.
From a management perspective, I appreciate that we can enroll or control devices on the back end for people who get a new phone and forget to handle Cisco Duo properly and need to add a new device.
It makes logging in easier than alternatives.
As a CISO, I like the Cisco Duo Identity Intelligence feature the most because it allows me to collect a lot of insights and reduce the time to detect issues on identity.
An example of how Cisco Duo helped in my organization is that we reduced the time to detect anomalies in user or identity usage within our organization.
Now with the automation in Cisco Duo, we are able to open a ticket in three minutes after the platform is able to understand that there is something wrong, whereas previously, it could take hours for our CM to understand and correlate to understand that there was something that was not good happening.

The features of Cisco Duo that I have appreciated so far include the seamless integration with many MFA features, so we can correlate everything in one app and don't multiply MFA apps, which is excellent.
Cisco Duo helps our company by allowing us to manage many internal solutions we use efficiently. If every hundred solutions we use each had a different MFA app, we simply couldn't manage that on our phones; it would be too complicated. For security purposes, we want a real posture approach for our MFA to correlate who has access to what, making it easy for our internal security team to give access to those who can access the app.
View full review »What I appreciate the most about Cisco Duo is the advanced license, which incorporates regional security such as geofencing, and I think that is quite valuable to have included. The bypass codes are also very useful from an administration point of view.
I think the integration of identity security into Cisco Duo's IAM solution is highly beneficial against modern threats, as it is integrated with many technologies and service providers to cover MFA, and it is quick and easy to set up.
I saw the benefits of Cisco Duo immediately after deployment; we started seeing spoofing attempts where the MFA request was not approved because the user was unaware of someone logging in. Clients I implemented Cisco Duo at immediately feel more confident in their security environment, and we can see a lot of illegal attempts to get in, giving me faith in the product.

Cisco Duo benefits the company by increasing the security footprint, and it is easy to manage users, disable users, or bypass if needed in case of an emergency. The MFA feature is particularly strong, with an excellent application interface. The dashboards and everything about managing the product is clean and intuitive.
View full review »When it came about, I was a big fan of the risk-based authentication feature of Cisco Duo. That was a big win. Additionally, the Verified Push after the Cisco breach was important, as Cisco recognized that they had to do something about that and they came up with the Verified Push, which is also a very good idea. Nowadays, if I would have known a couple years back what I know today, I would not have worried about that too much because I would have just moved over to passwordless and phishing-resistant MFA means in the first place.

I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient.
My experience with Cisco Duo's strong security authentication system has been easier.
It's easier to log in. Cisco Duo is user-friendly; users simply put in their email address and are redirected to their Okta page, making it straightforward to use. It's hard to screw up.
Cisco Duo's Identity Intelligence capability to detect and respond to identity-based risks is good. While I don't necessarily use it directly, I'm sure we implement it, though it might not be noticeable unless specifically pointed out.

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.

The features of Cisco Duo that I prefer the most include, first of all, 2FA. 2FA is pretty good because it is simple, and the simple way is what all users love. That is the top feature for Cisco Duo. I also appreciate all the features overall. I appreciate that with Cisco Duo, many people may think that it was just for 2FA, but now it functions as a full identity provider. That is a pretty good upgrade. I like the whole product and how it increases and develops on a huge scale.
I can tell you that for my company, these features benefit us because we work for other customers, so we help them to use these features. When we listen to the client and when we hear that there is something we can use, for example, Cisco Duo, it will be 2FA, it will be for device posture check, and so on. We are offering Cisco Duo straight away because, first of all, we have expertise in Cisco Duo, we know this product, and we have good experience with it.

View full review »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.

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.

View full review »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.
View full review »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.

It's really easy to quickly see if users are locked out from their device, firmware code, or just all the little dashboards and reports I can run to give the security for monthly reports. The dashboard's really good.
View full review »Right now, we're only using multifactor authentication. That's the most useful to us right now.
Reduction in risk is the whole point of multifactor. It's authenticating and augmenting the credentials and authenticating the individual that is trying to access your environment. It definitely reduces risk.
I would characterize Duo Security’s user authentication and device verification for helping to prevent identity-based attacks as good. It's intuitive for the users. It's easy to set up. The centralized management for our IT health service desk is good and doesn't take a lot of time. They're skilled with it. I really don't have any complaints.
The Duo Portal for our IT staff is efficient. It's utilized on a daily basis, and they're good with it. So I think it does allow staff to concentrate on other tasks.
I would say it's good at establishing trust for every access request, no matter where it comes from. Anything built by man can be broken by man. So there's always a challenge around that. They're trying to overcome those push bombing and challenges like that, and we're on that journey with them.
View full review »With Duo Security, it is easy to get that validation you need to make sure that you have security. It's very easy to set it up. It's simple, but it's secure. For me, that's the best part.
Integration for a partner is very useful because you can work with the API or admin API, whatever it is, and get a lot of logging details and pass them to your SIM. It's very useful for that.
Duo Security provides a high level of certainty regarding the identity of the individual performing an action. Whether it's logging into a system, using VPN, or utilizing Autopay, establishing that trust is crucial. I can't imagine any security company, organization, or IT team that wouldn't prioritize having multifactor authentication enabled when accessing critical systems.
Duo's user authentication and device verification are indeed effective in preventing identity-based attacks. The second factor authentication and clarification it provides are valuable. While there are certain situations where we might desire additional data from the API, I consider that to be a minor aspect.

It's easy to use, frankly. All it takes really is for the end user to download the app. For me, I have an Apple Watch; I don't even have to wait for my phone. I can accept the prompt right there and just be on my way.
Moreover, we are comfortable and have high confidence in the solution's user authentication; device verification can prevent identity-based attacks.
View full review »Duo is reliable and easy to use. I’m pretty happy with all of the features. The user experience is pretty good. People without any technical background can run the applications without any issues.
View full review »Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable.
The most valuable feature is just the ease of use. Out-of-the-box, there are so many integrations that are really easy to set up and use in a matter of minutes, depending on what the application is.
It establishes trust with every integration or any sort of application that you are using, whether it is VPNs, Azure AD, or remote desktop.
Duo provides single-pane-of-glass management. This is pretty important, especially if you are trying to respond to a security event. You don't want to look at different places and potentially forget to look at one spot. Now, we can have all our logs in one spot.
The single-pane-of-glass management does a really good job of optimizing the user experience, especially with the updates that they provide. They really take in customer feedback. I have been on several customer feedback panels before, and they do surveys. They are constantly improving the product.
View full review »The integration with Azure Active Directory and the AWS cloud is amazing, as most products nowadays require the creation of a customized integration. With Duo Security, it was more like native integration, and it took me five minutes to register.
The solution is straightforward, requiring minimal training and expertise to operate; IT staff have no problem understanding it.
The GUI is excellent, and the solution has valuable features, including policies and easy integration. It's a fantastic product.
Cisco owns Duo Security, and they are trusted everywhere, so establishing trust for access requests is never an issue. This is a major factor because when it comes to security, the solution must come from a trusted organization. We don't want to place our security in the hands of unknown third-party organizations; data leaks are a genuine concern.
I can't give specific details of my organization's security risks, but I can say that Duo Security has eliminated trust from my organization's network architecture.
I'm amazed by the product, especially by the ease of implementation. One of our major clients was equally impressed with the product. We use this solution to secure our network, which meets all our needs.
Compared with other products, Duo Security is excellent; I'm very impressed, and so are my colleagues. I can't speak highly enough of this solution. The support of hybrid work is vital nowadays, as many organizations are moving from on-premises to cloud and hybrid environments, so it's important for the product to be compatible with both environments.
In the enterprise segment, we require many solutions to defend against different threats, with each system responsible for its own security function. Duo Security remediates the specific threats we need and has all the necessary features.
I would rate the solution a 10 out of 10 in this area.

All features of the solution are effective, Duo supports BYOD policies by allowing users to authenticate securely from their personal devices. This flexibility allows employees to work from anywhere while ensuring that only secure devices can access corporate data. This has been very effective for our organization, and we have not encountered any issues. We use Cisco Duo and provide it to our clients as well. We implemented it and also use it internally. The IT and finance departments should be involved.

At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process.

It's simple. It's reliable. I haven't had any issues with it.
View full review »We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc.
Its ability to help reduce the risk of breaches is pretty good. I like its ability for user authentication and device verification.
View full review »The integration is the most valuable feature. The products talk to each other.
The products help us to detect and remediate threats.
For me and my customers, the best feature is that it's very easy to integrate with the existing infrastructure. It takes a few minutes to configure it.
The most valuable feature is the ability for users to connect securely to the office using the VPN. There's no way to breach security using Duo. No user can connect from a different device, which guarantees access on a per-user basis. The only way somebody else can connect is if the user shares their VPN password, as well as the six-digit code. This is a well-accepted, business solution.
It is very easy to set up, configure, and integrate this product. It is also easy, from the user's side of things.
The interface is such that all of the management can be done from a single pane of glass. You can integrate as many applications as you want, and it's up to the enterprise that dictates that. Overall, it's easy to manage and administer. There are not too many moving pieces, which would make things more difficult to administer and troubleshoot when there are problems.
From our employees' perspective, they are confident that they are the only people that can connect to their accounts. Access to their own accounts remains under their control, and they are the only ones that can connect.
View full review »The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature.
The product worked to establish trust for as long as I've used it. It's a more functional solution than some competitors, which I discovered during the POC process. I think that Duo Security considering all resources to be external is one of the reasons why they are at the top of their field.
Duo Security simplified establishing trusted connections, making it easier to implement distributed network solutions. I've always found it to be a good part of a layered defense strategy.
Most of the end users when I was responsible for implementation, didn't quite understand the value of the solution until it was demonstrated.
The tool does provide single-pane-of-glass management in my experience. I haven't implemented the solution for years, but I'm a user in my personal and professional life. Therefore, I can say that feature is essential in making Duo Security one of the critical steps in a defense-in-depth strategy.
I never had any problems maintaining network connectivity, and it always performs well.
Based on the logging I have seen Duo Security use, I would say their solution does help with threat remediation. It is an integral part of the defense strategy.
A robust two-factor authentication solution is a massive part of a proper defense strategy, and having Duo makes it easier to implement and manage that two-factor solution.
View full review »Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic.
Its ease of use is also valuable. From start to finish, you can get the whole environment set up within a couple of hours. Everything is easy to follow. The UI is good, and the process is very straightforward.
Simple authentication for VPN was our primary function, and it worked well for that.
As far as remote access, simple access, and authentication to gateways, it was perfect.
Distributed access for ISE has been pretty strong for remote access and works very well.
It has very strong network connectivity, which works reliably and well. It was very easy for people to connect and the app worked as it should. Just once people connected, they typically had to use a different tool from that point on.
Duo applies and maintains well network connectivity across campus and remote locations. Remote access from people's homes and branches is also strong. Network connectivity is its strength and does that well.
View full review »We needed 2FA for compliance. We already used Cisco across the board, so it made sense to use the product. We benefit from using the solution. We were unaware that some users were sharing logins and doing some things that went against policies. Once we had Duo Security in place, we realized that codes were not going where they needed to, and we could sort that out. The solution is easy to use.
View full review »The anti-phishing feature is the most valuable.
View full review »It's pretty easy for users to figure it out. We've largely non-technical people where I am. At first, there was a little bit of a speed bump trying to get everybody to understand why we were using it, but it wasn't too bad. Everybody pretty much embraced it. Its adoption happened over a course of a couple of weeks. It was fairly smooth.
We also use Cisco Secure Email and Cisco Umbrella. It integrates pretty well with them. We haven't had any issues.
Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application.
View full review »It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work.

Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional.
When it comes to securing infrastructure from end to end so that we can detect and remediate it, it's pretty good. It's a little proprietary. A lot of it is based around its own ecosystem and we've started looking at other solutions that are more open-source or a bit open to more collaboration. That's something that we're picking up with Cisco.
View full review »Everything is all in one dashboard, so it makes the administration very easy.
Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have your dashboard and can have one look in your dashboard and see everything. It's on one pane of glass.
View full review »The most valuable feature of Duo Security is the ability for the user to easily approve access. The application prompts the user, and they can see the location and the IP address. This makes it easy for the user to approve it and go through the process of logging in to the VPN.
Duo Security can be used for any type of authentication apart from that for VPNs. It saves time and prevents problems because it is user-friendly.
The two-factor authentication is valuable because that is the use case for which we are using it.
I like the two-factor authentication, which gives another layer of protection.
It's very important for our organization that this solution considers all resources to be external. Our company has thousands of people who access from outside, and it's hard for us to know which one is legitimate and which one is illegitimate. Having two-factor authentication with Duo helps us to implement a second layer of authentication so that we know for certain that the people who are accessing accounts are legitimate.
It's a great solution for securing access to the applications and network because we can integrate the solution with all types of applications. The system has the ability to integrate customized applications built in-house and those that were brought in from outside. It integrates with network access as well, such as when you want to access a different node. It has multiple ways to authenticate applications, network access, etc., which helps us a lot to spread the solution across all our assets.
That the solution helps support hybrid work is very important to our organization because people access accounts from everywhere. Duo Security gives us the second layer of protection.
The solution provides a single pane of glass management to help us monitor all of the access.
Duo Security helped us remediate threats more quickly.
View full review »It's nice to have that push notification with the app and it's pretty easy to use. Our users are usually pretty open to it, and it's pretty easy to onboard people.
It also seems like it's accurate, and you can add multiple devices to your account.
In addition, typically, if it detects that you're on an internal network, you can bypass the Duo portion of it. That way, people don't have to do MFA when they're on campus.
Another feature is the single pane of glass management. That's important for analytics and also for troubleshooting. It means there's one place that you go to at least start the troubleshooting process. It also helps with the user experience because you can manage all the user accounts from that one spot, including setting up new users, making adjustments, editing their preferences, et cetera.
The ability to work online and offline with two-factor authentication is the best feature. Usually, with products, you have two different tokens. For this product, there is just one.
It is a good product to assess the access. Overall, it has a timely response as far as when you need to click. It is very interactive. It is not like you have three seconds, then it is gone. It gives you the time to do it.
It provides single-pane-of-glass management, which is pretty easy and straightforward. Because we manage multiple access tiers, it allows us to essentially manage everything from one viewpoint and not have many viewpoints for the same product. This is important because it is a time and resource saver. It also saves us money.
The single-pane-of-glass management user experience is pretty good. It is one of the best ones that I have worked with so far.

Michael Patsourakos
Network Engineer at a financial services firm with 10,001+ employees
I like the set time that users can log into devices during the day and how many times they can do so. I also like the ability to restrict the regions from which the user can get in. Users outside of our country or even the town cannot log in.
View full review »We like the different ways that it allows you to push notifications to people. It can do text, a phone call, and email. We liked the versatility for all of our different end-users, regardless of their level of understanding of the technology.
It does a very good job of helping workers feel safe and secure and supported. Some people view it as just another layer of things that they have to go through, but the simplicity of use, such as being able to call in if they need to, or receive a text, takes into account all levels of end-users and what it takes to get that authentication from them.
It is also important that the solution considers all resources to be external. When you already have certain pieces of security in place, it's really difficult to just rip everything out and replace them. You need something that can start as a standalone solution and then slowly work its way into the rest of your corporate network. When we changed buildings, we had a lot of people working at home for the first time and suddenly using different devices to do their day-to-day jobs, so that aspect became very important.
When it comes to supporting an organization across a distributed network it becomes very important, again, because the traditional method of backhauling security solutions to a central point gets very dicey. It starts to generate a lot of traffic across a wide area. And what happens if some of that can't get back to you? Or what happens if you're dealing with low bandwidth or other scenarios? Plus, depending on where you're at, they may view that as some kind of encrypted back tunnel and not let that happen. Whereas Duo, because it's more distributed and it's trusted out there, allows you to drop something in on a footprint on a very large scale. Before, it would've been a nightmare to get all that configured properly and working.
In addition, the single pane of glass management is very important because security is an extremely complex issue. If you have all these different windows to look at, you're not sure if somebody was looking at this window at this particular time, or if they were over there at that window and missed something. The single pane of glass is very important because the biggest enemy of security is complexity. If you miss something because somebody is not watching the right dashboard, it can blow right by you.
The single pane of glass management does a pretty good job of helping to optimize the user experience, in my particular role. And from what I hear from my team, they're very happy with it. They feel it does a good job for the clients and they love the simplicity.
This solution has been most valuable for locking up our VPN solution and providing secure web protection.
View full review »The ease of use and the ease of management of all the users have been key for us. The setting up of devices in Duo has been really easy as well. It's better than all the other ones I've worked with.
Another important feature is that Duo considers all resources to be external because even the internal ones look like external ones, and people click on stuff and get caught. It's very important to be more cautious than ever.
Also, the single pane of glass management works very well. That feature is very important because we have a lot of admins who have to manage Duo, and it's much easier when it's a single pane of glass. That single pane is also great because it's easy to enroll new devices.
View full review »- The easiest feature is the token or the app on your phone that gives you the code to log in.
- It provides a single pane of glass for management and that helps optimize the user experience.
- We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through.
- It does a good job of establishing trust for every access request. It checks all the boxes I need and, as a reseller, it makes it easy for me to sell. I'm happy with it.
Multifactor authentication is the most valuable feature.
As for establishing trust for every access request, that's exactly what this solution does. Outside of having a username and password, you have to get authentication from Duo as well.
You can never eliminate trust, but what Duo Security does do is add an extra layer of security. When it comes to the internet, networks, inbound traffic, and outbound traffic, you're always subject to a potential threat. Duo Security just adds another layer.
It's a great addition to the security of any network infrastructure.
In terms of helping workers feel safe, everyone knows that the information within the enterprise is safe because the people that are logging in have been authenticated in more than one way.
It's pretty easy to maintain network connectivity once it's set up; the end-user uses it to log in. It's not something that you have to constantly manage and deal with apart from pushing updates. It's pretty much self-managed.
In terms of consistency across workspaces, it works all the time, except for when a forced update is needed.
It helped us remediate threats more quickly. For instance, if someone accesses your credentials or you leave your laptop open and someone gains access when it times out, you still need the Duo code that is sent. A new code is always needed to be able to access that laptop or even that phone. Then, from there you're able to safeguard the information that your company has.
Nowadays, data is the number one commodity, so protecting that at all costs is really important. Duo helps with that with end-users. The thing about end-users is that they are volatile. You can't really control what someone does. So, Duo security helps with managing that by having them implement a new time code that's always sensitive.
View full review »The single pane of glass management is very important and it is part of the reason we went with Duo. Anything we can do to save time for our administrators, help desk staff, and engineers, is valuable to us.
View full review »The ability for users to authenticate via phone, from any random phone number, has been very helpful for managing a distributed workforce. Using it across a distributed network for securing access to our applications is big for us. It works very well, and we have no major complaints about the integration of any of our third-party applications.
We have a high level of confidence in the platform, especially for identifying potential logins from unexpected geolocations. The data associated with logs is very helpful for helping to make that determination.
It's very important for us that Duo Security considers all resources to be external, especially as we lead up to Zero Trust. It needs to be like that.

The multi-factor authentication process and the geo-locking features are great. It provides us with statistics about the devices that are used to perform the second authentication factor.
Upon successful connection, it tells us where and what device is being used to perform the second authentication factor. For example, when I log in with it, we'll see that I have my iPhone 11 and that it is located in the area via its IP address.

We have many users who either refuse or are unable to use a smartphone. Buying them hardware tokens is out of the question, as well. The availability of mechanisms that can achieve MFA, but do not rely on either of those two supplementary elements, is critical for our user population.
