A highly-scalable multi-factor authentication solution
Pros and Cons
  • "The multi-factor authentication process and the geo-locking features are great."
  • "We had some trouble with the password reset function."

What is our primary use case?

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.

What is most valuable?

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.

What needs improvement?

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.

For how long have I used the solution?

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.

What do I think about the scalability of the solution?

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.

How are customer service and support?

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.

Which solution did I use previously and why did I switch?

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.

How was the initial setup?

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.

What about the implementation team?

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.

What's my experience with pricing, setup cost, and licensing?

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. 

What other advice do I have?

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. 

Which deployment model are you using for this solution?

Provides heightened security and has a helpful customer support team
Pros and Cons
  • "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."
  • "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."

What is our primary use case?

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

How has it helped my organization?

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.

What is most valuable?

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.

What needs improvement?

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.

For how long have I used the solution?

I have been using Duo Security for about two years.

What do I think about the stability of the solution?

Duo Security is a pretty stable solution.

What do I think about the scalability of the 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.

How are customer service and support?

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.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

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.

What was our ROI?

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.

What other advice do I have?

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 for Duo Security is all user access to email.

How has it helped my organization?

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 is most valuable?

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

What needs improvement?

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

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

For how long have I used the solution?

I have been using Duo Security for six months.  

What do I think about the stability of the solution?

Duo Security's stability is perfect.

What do I think about the scalability of the solution?

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

How are customer service and support?

I have never used Duo Security's support. 

Which solution did I use previously and why did I switch?

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.

How was the initial setup?

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

What was our ROI?

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. 

What's my experience with pricing, setup cost, and licensing?

The cost of Duo Security licensing is OK.

Beneficial viability, good authentication, and reliable
Pros and Cons
  • "The most valuable features of Duo Security are visibility and OTP authentication. The OTP is very important because it is a self-enrollment feature, you are able to enroll users very quickly with a shorter time period."
  • "Duo Security could improve by being more compatible with other vendors."

What is our primary use case?

Duo Security is multi-factor authentication, specifically a two-factor authentication. It authenticates users so that you can know they're legitimate in the network. It can be used for mobile banking. For example, when you're doing mobile or internet banking with your phone, when it uses OTP, it is using Duo Security.

What is most valuable?

The most valuable features of Duo Security are visibility and OTP authentication. The OTP is very important because it is a self-enrollment feature, you are able to enroll users very quickly with a shorter time period.

What needs improvement?

Duo Security could improve by being more compatible with other vendors.

For how long have I used the solution?

I have been using Duo Security for many years.

What do I think about the stability of the solution?

The solution is highly reliable.

What do I think about the scalability of the solution?

Duo Security is sized per user. You can even have Duo Security for five users or 3,000 users. It depends on the size of the organization.

The solution is scalable.

How are customer service and support?

The technical support is of a very high level. If you have a problem they will be able to support you. They are able to log in remotely as an engineer to give assistance. If you have the upgraded license then the support is even better and they will do everything for you if you have a problem. The support is extremely good.

How was the initial setup?

The installation is very easy to do for Duo Security and it can be done with one person in one hour.

What about the implementation team?

We have one person for maintenance of the solution and they do not need a lot of training to be able to do it. There is a manual that can be followed.

What's my experience with pricing, setup cost, and licensing?

The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support.

The license can be purchased monthly, quarterly, half-year, or annual.

What other advice do I have?

I would recommend this solution to others. I have seen it being used in large banks and there has never been a complaint about them. It is a very good solution.

I rate Duo Security an eight out of ten.

Stable, easy to set up, and has useful push notifications, integrations, and mobile app
Pros and Cons
  • "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. 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."

What is our primary use case?

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.

How has it helped my organization?

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.

What is most valuable?

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

What needs improvement?

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.

For how long have I used the solution?

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

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

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.

How are customer service and technical support?

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

Which solution did I use previously and why did I switch?

We didn't have anything in place.

How was the initial setup?

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.

What about the implementation team?

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.

What was our ROI?

It has provided ROI.

What's my experience with pricing, setup cost, and licensing?

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.

Which other solutions did I evaluate?

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.

What other advice do I have?

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.

Which deployment model are you using for this solution?

Helps to log in to Citrix, VPN and servers
Pros and Cons
  • "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 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."

What is our primary use case?

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. 

What is most valuable?

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. 

For how long have I used the solution?

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

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

The product is very scalable from what I have seen. 

How are customer service and support?

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

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

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. 

How was the initial setup?

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

What was our ROI?

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

What other advice do I have?

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.

A secure solution to protect a database
Pros and Cons
  • "The two-factor login is great. I receive a message and just have to press okay."

    What is our primary use case?

    We use Duo Security to access databases, which are in the cloud. It's two-factor authentication mostly.

    What is most valuable?

    The two-factor login is great. I receive a message and just have to press okay. And then I am in. Also, the connection is very fast.

    What needs improvement?

    I haven't experienced any issues with Duo Security, but I'm only on the front end, I don't see the back end. I don't know what the IT guys are struggling with. From the front end, it's very fast and it hasn't missed a beat, so to say. As soon as I log in, within a second, I receive a message on my mobile, and as soon as I hit okay, that is within a second, then it's already passed on to the database where I need to be. It's lightning-fast, I've never experienced anything like it in the past.

    For how long have I used the solution?

    I have had experience with Duo Security for roughly six months.

    What do I think about the stability of the solution?

    Duo Security is very stable.

    How are customer service and technical support?

    I have not needed to call technical support relating to Duo Security; however, the guys from Cisco are very supportive, but that also has a lot to do with my relationship with Cisco. I've known most of the support guys since the late '90s. If I have an issue, they respond to my requests within five minutes.

    How was the initial setup?

    For me, the initial setup was very simple. All I had to do was download an app, log in, and that was it. 

    What's my experience with pricing, setup cost, and licensing?

    I was not involved in licensing negotiations, so I can't speak on this matter.

    What other advice do I have?

    As a user, I would give Duo Security a rating of nine out of ten.
