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.

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.

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.

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.

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.

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 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.

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.

What I appreciate the most about Cisco Duo is the advanced license, which incorporates regional security such as Geo-fencing, 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.

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.

Cisco Duo Push is one of the magic features and it really helped to accelerate the two-factor authentication process. Duo Push makes things easier for my team and users by accelerating two-factor authentication.

Besides Duo Push, Cisco Duo as a cloud service allows for single sign-on on cloud services and supports integration with unlimited applications, which is really helpful for any organization.

Cisco Duo has positively impacted my organization by helping to implement zero trust. It also ensures that every user is protected against phishing or password theft.

I have noticed specific outcomes since using Cisco Duo, as it has reduced security incidents according to my records and reports for a year.

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.

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.

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.

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.

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.

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.

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.

Paul Mhiripiri
Networks and Infrastructure Manager at a financial services firm with 201-500 employees

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.

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.

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.

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.

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.

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.

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.

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.

Sales engineer manager at a wholesaler/distributor with 1,001-5,000 employees

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.

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.

  • 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.

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.

The feature that we find most valuable is Duo's ability to provide MFA via mechanisms that do not require a smartphone. 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.
