Cisco Duo Reviews

A lot of our use cases were for customers to get their cyber insurance renewed. It was a requirement and they had to scramble to figure out a way to get multi-factor authentication in place.

It's made things easier for our customers with all the different ways to sign in. It's pretty painless once they get used to it. Once customers understand it, it checks all the boxes for them. It's easy for them to use. It also works with a lot of Cisco's other products.

• 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.

Sometimes, it's a little harder for customers to adopt.

Also, when it comes to the single pane of glass for management, there are some mixed reviews and opinions that say there could be some other options. But those are very unique cases.

The majority of my customers are really good with just the two-factor authentication and don't really take advantage of a lot of the extra bells and whistles that it has. Getting them to adopt more of those features, versus asking for anything new, would probably be where my first step would be.

I have been using Duo Security for about a year and a half.

The stability is good. I've never had an issue with it crashing or having bugs.

I've never had anything outgrow it. That's for sure. You just add licenses.

Tech support has been great. I've only had to open two cases and they've been very helpful and made it straightforward.

I've been involved in the deployment of Duo Security a few times and the documentation makes it straightforward.

Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues.

We're a Cisco partner, so once the two-factor requirement kicked in and became mandatory for our customers' cyber insurance, we just gravitated right to the Cisco solution.

The proofs of value that we've done are really what sells it. You put it in, get them using it, and then you just buy the license and you don't have to go back.

Employees start off saying, "This is another thing we have to do," but once they get it set up the way they like it, it's very easy. And if anybody gets locked out, we get an email and it's easy to unlock. If the unions were able to adopt it, anybody can.

Overall, it meets all my needs, including price point, and I've been very happy with it.

We use it for two-factor authentication for end-user and administrator login. We wanted to secure our endpoints.

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.

I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services. We're having to use it a lot. I understand it, it's just part of it. That's not specific to Duo. That's two-factor authentication in general.

I've been using Duo Security for about a year.

It's stable. We haven't had any downtime that I can recall or any problems with maintaining network connectivity.

Any issues we've had have been local to a specific user. Maybe the phone number was not set up right or there was some conflict as a result of somebody changing a device, but it's always been pretty straightforward to get that kind of thing resolved.

We started off with a small deployment and, in one or two steps, sent it out to everybody and it scaled fine. We didn't have to change anything in our setup.

We have about 1,200 users across 60 branches around the U.S. We occasionally have people using it internationally and we're able to handle that fine with our geographic location blocking or allowing, as the case may be. It's a fully virtualized environment. We have a lot of remote users, people who work in remote fields. As long as they have a cell signal, it works.

I have not had to deal with any support for Duo. The less I have to talk to support the better, for sure.

This is our first venture into two-factor authentication.

We didn't have a specific problem we were trying to solve when we got it. We were just trying to add more and more security. We did have regulatory requirements for two-factor authentication and that is what drove it.

The deployment of Duo Security was mainly a project done by our network and security team, but I was involved in it to some extent. I found it pretty straightforward. As enterprise-wide security solutions go, it wasn't too bad.

We got it integrated with Active Directory. There were some struggles there that I don't know the specifics of because our network team was working on that. But once everything was set up, it was pretty easy to add a new user and do whatever we wanted to.

It took a little time for our users to get used to it, but everybody took to it pretty well. The users don't really have to interact with it other than getting their push notifications. For them, it's easy. It requires minimal training. It pops up and it's all pretty self-explanatory.

It's pretty easy to use as two-factor authentication systems go. We evaluated a few others, including the Microsoft two-factor authentication, a little bit, and one other, and Duo ended up being our favorite. Part of that was because we're in that Cisco ecosystem and we were able to integrate it with our other services that are all cloud-based. It fit in pretty well for us, and it would for anybody with a similar setup.

Duo was also the least obtrusive to the user and the ease of administration through the administrative portal was a little better.

Fortunately, we haven't had to evaluate it when it comes to helping us remediate threats more quickly, but we're confident that it will.

Regarding resilience in cyber security, two-factor is definitely a must-have. We're satisfied with it as far as that goes, in addition to it fulfilling our regulatory requirements.

For our use case, for logins, it just works.

We try to use the solution for pretty much everything that we can use with it. The tool helps us to get into our dashboard APIs, and log into Citrix, VPN, and servers. 

I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great. 

We have been using the product for about two to three years in our company. 

I haven't seen any reason to think the solution is unstable. 

The product is very scalable from what I have seen. 

The solution's support is pretty good. It helped us quite a bit. Both Meraki and TAC have been pretty helpful. 

Positive

We switched to Duo Security due to the cybersecurity threats that came with COVID. There was a big one that came against us at one time, but we were able to squash it pretty quickly. The threat was not able to get into the mainframe because of the solution. 

The tool's setup was easy and we didn't require too much outside help to set it up. 

As a network and security guy, security is my return and it has been better with the product's use. 

I would rate the solution a nine out of ten. Duo Security can get spotty at the back end but it doesn't break. It would be great if I could use the product to log into the routers or switches in the infrastructure. We already have Active Directory enabled in our routers and switches. However, if we could do two-factor authentication, then it could go a long way since no one's getting into them unless you want them to. We are all for more security in healthcare. 

We use Duo Security to level up security and access to internal systems.

Duo Security has provided us with heightened security. That's the biggest benefit because, nowadays, security risks are big due to hacking. This solution narrows down a lot of things that we have to go through.

If you have to log in to something, you must go to Duo Security to confirm that you're who you are on your phone. From there, you go back to the app, and it allows you access.

When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality. Sometimes, you have to go and push from the app, go to Duo Security, and then go back over after you've accepted the push. It would be good if a seamless web comes down, you press the button at the top, and it goes away while you're still in the app.

I have been using Duo Security for about two years.

Duo Security is a pretty stable solution.

Duo Security is a scalable solution. You can easily download the app, log in, and you have access. Scaling is not an issue with Duo Security.

Duo Security's customer support is very helpful, going above and beyond what they normally need to do to get things fixed and resolved. I can always reach out to my reps, who try to figure out what's going on to help me.

Positive

Since I changed companies, I can't remember the old solution, but it was probably some Microsoft solution. It did almost the same thing as Duo Security, except that Duo Security has the push. So instead of going back and finding the code, it can easily just push to the app, allowing you access. So it's a little bit faster to access your systems than having to find these different apps.

We have seen a return on investment with Duo Security because getting hacked once would cost us millions. So investing in a solution like Duo Security saves us all that money.

Most solutions do what we're trying to use Duo Security for. It ensures a person has different access to the system via a different device like a YubiKey.

Duo Security has helped to improve our organization's security posture through reassurance in giving out access. Having something like Duo Security on the back end can help pinpoint who's logging in and ensure there is no random bot.

I highly recommend Duo Security because it's still seamless from my standpoint. I don't know how it would be on the back end, but it'd be a great application for any organization wanting to heighten its security on user access.

Overall, I rate Duo Security ten out of ten.

Our primary use case is multifactor authentication for our VPN users. We didn't have multifactor authentication before. After we integrated Duo Security with our systems, everyone has been using it, and it has given us peace of mind when dealing with VPNs.

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.

Integration between Duo Security and FTDs needs improvement. Integrating Next Generation Firewall safety with Duo Security currently requires a proxy agent between Active Directory and the appliance. It's an additional factor that we need to think about. It would be great to have direct integration with FTD so that we don't have to worry about middleware products. For the rest of the Cisco Secure solutions, the APIs need improvement.

Duo Security needs to improve the delivery of text messages to the users. This has been a big pain point for us over the years. Though we understand that the local telecoms are the ones responsible for the final delivery of the message, there should be a way to improve the process. Some users don't use the application and rely on SMS messages. It is a problem at times because the messages are not delivered.

We've been using Duo Security for almost six years.

We use Cisco Umbrella, ISE, FirePOWER Services, Next Generation Firewalls, FTD, ASA, and Duo Security.

The stability of Duo Security is great. We receive notices for any problems or issues in a very timely manner.

The solution is generally easy to scale. If you have the ability to deploy Duo Security yourself or can leverage third-party integrators, there should not be any issues with scalability.

Cisco support for Duo Security has been great. We haven't had many cases, and most of the ones we have had were related to SMS and text messaging delays.

On a scale from one to ten, I'd rate technical support at eight. They are quick to provide solutions but can improve on working with third-party service suppliers so that end-user experience is better.

Positive

Deploying Duo in our environment was very easy because of the pre-staged configuration. It was very quick, and in one to two days, we had a VPN concentrator using Duo Security.

Duo Security was initially deployed using a consultant, but afterward, we deployed multiple additional VPN concentrators ourselves.

The return on investment has been huge in terms of protection from cyber-attacks. We have been able to protect our employees by having multifactor authentication. This is invaluable for companies in the current threat landscape.

In terms of support, it's always great to have happy users who are able to easily log in to our environment through VPN without having to bother about non-working software agents or any other type of authentication platforms.

My advice to you if you are evaluating Duo Security would be to do your research and compare it to other competitors. If you are a Cisco-oriented company, you will see that there are several benefits to using Duo Security. You will also see that it has the edge over other solutions on the market.

On a scale from one to ten, I would rate Duo Security at eight. The stability and user experience are great, but there's room for improvement in terms of text message and SMS delivery.

We mostly use it for our AnyConnect VPNs and two-factor authentication.

We use Firepower Defense as a firewall, and we have implemented the IPS system on the firewall. Previously, we had ASA, and two-factor authentication was with the code, but now, it's with a push notification. It has somehow made it easier for non-IT employees to easily connect to the VPN, but it, as such, hasn't saved any time. It didn't reduce any tasks. 

It hasn't helped consolidate any tools or applications because we're not using any other security components that can be integrated with it.

The two-factor authentication is valuable because that is the use case for which we are using it.

We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version. I didn't know why, but it did not function. I haven't tried to update it since then, but that could be an area of improvement.

I've been using Duo Security for almost four years.

It's stable.

It has good scalability.

They were helpful and fast 90% of the time. They have knowledgeable tech engineers. We didn't have many problems, but any problem that required a case to be opened was resolved quickly. I'd rate their support a nine out of ten.

We didn't use a similar solution previously. We went for this solution because of the consistency of Cisco products and the best cases that it provides. It fulfills our needs as a company.

It was straightforward. I had some issues, but mostly, I followed the complete path from sandboxing to testing and then going live in production.

We have two people, me and my colleague, but it's mostly me.

I am not involved in its pricing, but we haven't yet seen an ROI.

I'd recommend using it. You can read about the product and implement your infrastructure.

I'd rate Duo Security a 10 out of 10.

We use Duo Security for two different parts. One is for access to one of the servers, and the other one is for accessing the VPN connection.

It helped free up the time of IT staff. It helped them to manage the control within the users. They can control who gets access to which part of the system. For example, if there is a group of people who need a certain type of permissions, they can set them up easily. They can gather them in groups and give specific permissions. They can also give specific permissions to only one person.

It has been very useful in detecting or fixing threats that come into the organization.

It's a good thing for the authentication of your credentials. It's easy to use for the security part, and it helps to improve our security posture.

They can make authentication easier. It should be done in a shorter time. Sometimes, it can take a bit more time to get the answer on your phone. You have to wait a bit longer to get the SMS code and other things. There can be some internet or connection issues. They should make it faster because sometimes, it's urgent, and you need to access something as soon as possible.

I have been using this solution for about two years.

In general, all Cisco products, not just the Duo product, have a lot of stability.

Their tech support is pretty good, but there are some disadvantages. Sometimes, they take a long time to answer. I understand that some of the issues are not very easy, and it takes time to research them. I'd rate them an eight out of ten.

Positive

We didn't use any non-Cisco products. We were only using Cisco products. The IT part of our organization is using the Duo authentication system, and we are using another part of the server for authentication.

It's not very hard. It doesn't take long. The IT gives us an access code for it. 

I just downloaded the app, and after that, just got the security code from that department. I entered that, and it was done. That's it. If you are changing your device and they're just resetting your data, it can take two or three minutes maximum for a new device.

I'd rate Duo Security an eight out of ten.

Our primary use case for Duo Security is all user access to email.

Duo Security improved my organization by helping us secure all access points within the company infrastructure. 

Duo Security helped our company consolidate tools, including email and VPN.

What I find most valuable about Duo Security is that it is our one-stop application for multiple MFAs. 

Duo Security could be improved with the addition of more applications. 

Duo Security has not helped free up our IT department's time.

I have been using Duo Security for six months.  

Duo Security's stability is perfect.

Duo Security's ability to scale is perfect. We have 5,000 people using it in four countries. 

I have never used Duo Security's support. 

We previously used integrated multi-factor security from Microsoft 365 and Fortinet FortiToken. We made the switch to Cisco because we wanted to handle everything in one application.

I was not involved in the initial deployment. I do know however that 10 people were involved in the deployment. 

We have seen a return on investment because with Duo Security, we do not have to pay for multiple applications. Instead, we pay for one solution. 

The cost of Duo Security licensing is OK. 

When our users are connecting to our Cisco VPN, Duo effectively ensures that they are who they say they are by taking a second factor into account, such as the cell phone that was used to create their profile. To do this, it sends them a second mode of authentication, such as a PIN or push confirmation. It also geo-locks who is allowed to actually log into our systems. We have it locked to the continental United States and Puerto Rico, and one outsourcing firm that we work with.

Once you have it set up, all you really have to do is add people to a group in the active directory and send them the instructions on how to do it. If you have a lower technical user base, you may have to walk them through it. But once it's set up, it really is automatic.

Not a single person from our IT staff really needed anything other than the instructions. Of the 15 people in our test group, nobody actually needed instructions on how to use it either — beyond what I just wrote up and sent them.

As we get to the older population in our company, the less technical population, we're probably going to have to walk them through it or hold their hands a little bit.

Within our organization, there are currently 15 employees using this solution. Eventually, we will have all 221 office staff users with it set up. Still, we'll probably top out at about 80 users a day.

We will increase the overall usage as our users increase. So, if we hire another 10 people, then we'll buy another license.

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 had some trouble with the password reset function. When a user's password is expired, you can prompt them using Cisco AnyConnect — a password management feature — to change their password in the same channel during the login process. We had a lot of trouble configuring that. As a result, we now have a second channel that bypasses Duo to allow them to reset their password.

For this, we needed Cisco support, Duo support, and our network administrator all lined up. It should have just been something that they could have just configured, but they weren't able to do it in the same channel. We had to actually create a second channel. When you do this, people will try to log on and it'll tell them that their password is incorrect. They'll realize that their password is expired because it's been 90 days. Afterward, they'll have to then go back to AnyConnect, change the channel that they're logging into, attempt to log in, get the password prompt, disconnect from the AnyConnect, and then reconnect using the Cisco Duo multifactor authentication — this is extremely complicated.

Still, it's really only a problem for a small subset of users. The ones who ignore the notifications 10 days before saying, "Hey, change your password."  So, it's not as big of a deal as it sounds. Just by having a functional way to do it, it makes it so that if nobody's on staff, the user can reset their own password without having to call us in the middle of the night on a Saturday, because that's the best time for those passwords to expire. 

Also, it would be nice if it was easier to modify the splash screen that comes up when entering your username and password.

We actually just configured Duo Security — we're in the process of pushing it out. Currently, we've been using it for the past three to four months.

Scalability is definitely up there. It could easily handle many, many, many more authentications than we are currently or ever would use. It could definitely go far beyond what we are currently using.

The technical support agents are definitely knowledgeable; they give us plenty of recommendations on how to do things. They are very quick to send us white papers describing how to fix things ourselves. 

Although they try to push us toward a self-help model, they do eventually get online with us via a WebEx chat with the Cisco reps and help us out. We've never really had any problems finding somebody from chat support that wouldn't jump on to the WebEx meetings with Cisco premium support.

We didn't have anything covering multifactor authentication. We were using Cisco AnyConnect with the tie-in to the active directory, but we just had the single factor — the username and password. Duo allowed us to greatly enhance our security. Now, not only do users have to know their username and password, but they also have to be able to receive the second-factor authentication in order to get in. The same goes for anyone trying to break in.

The initial setup was complex, but due to the support that we received during the onboarding, it was very simple with the exception of the password reset channel that I mentioned earlier that we tried to use but didn't end up doing. The way we have it set up now is actually how it was configured during the onboarding process. It just would've been nice to have had it functionally work — to have that all in one channel.

Regarding deployment, we have an in-house person, but we still had Cisco Duo onboarding support to assist us with the setup. If you have a CCNA, you'll probably be able to do it yourself, but it's just much easier to do it with onboarding support.

The functional part of the onboarding process only took roughly an hour. Including troubleshooting our channel issue, we spent roughly 16 hours before we just decided to go back to the original build.

Our licensing fee is currently on an annual basis.

There are two levels of support with Duo that we were considering. The first level of support is just the two-factor authentication — it doesn't do anything else. But the second level of support provides us with network access control. This basically allows us to say, "Hey, your iPhone hasn't been updated in 10 years, update your iPhone to continue using this service." Or, "Your Windows device does not have updates." It also provided us with the geolocation feature. We were experiencing a lot of break-in attempts from Moldavia. So, thanks to this feature, we just locked out Moldavia. If nobody in Moldavia can connect to our system, then nobody in Moldova can hack us. 

If you're interested in using this solution, be sure to get the onboarding team to set everything up during the onboarding phase. Set up a proxy server if you can and get them to do everything during the onboarding phase — then you won't have any problems.

Compared to the after-purchase support, the onboarding people are a lot more willing to just take over your computer and set things up for you.

Overall, on a scale from one to ten, I would give this solution a rating of ten — it's the best. 

Duo Security provides multi-factor authentication for anything that requires multi-factor authentication. It could be our internal corporate services, such as a single sign-on portal, or applications, such as Google Cloud.

It is very easy for users to enroll. There are a lot of insights that we get from using the app on devices that people use to authenticate.

The push notifications and the integrations they offer are valuable. Their mobile app is very useful. It is very easy to use.

The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. There was no way to (re)name 3rd party OTP accounts so it got confusing when multiple ones were existing. In addition, each account took a lot of space on the screen, they condensed it in the new version to make it easier for people that have a lot of accounts added. Duo has a beta program and actively solicits and listens to feedback which personally I think is great.

It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system.

I have been using this solution probably since 2014. In this company, we have been using it for two years in total.

It is stable. Over the last six or seven years, I didn't have any issues where something wasn't working.

The maximum number of users that I have had is around 600, and I haven't found any issues there. In my current organization, every employee is using this solution. We have 250 employees.

I have not interacted with them. I never had to open a support case.

We didn't have anything in place.

It is pretty straightforward. I just need to log in to an account and integrate systems that should be using Duo Security. That's basically it. It probably took me an hour to roll out the accounts.

IT support helps users if they run into problems with the application, but that's about it. There is no separate team for its maintenance and deployment. There are a lot of service options for our users. They don't even need to contact IT support. On a new phone, they can even do it on their own.

It has provided ROI.

Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs.

We looked briefly at Okta Verify. It is the Verify app from Okta to use a single sign-on provider. It had the same price but far less functionality. It was a no-brainer to just go with Duo Security.

I would advise others to look at the integrations that are available and see if they can roll it out to as many applications as they can. Encourage users to use Duo Push versus the six-digit pin code that the applicant generates.

I would rate Duo Security a nine out of ten.
