Scalability is excellent. Being cloud-driven, our customers are not concerned. They can simply purchase licenses as they need them, and scale up or down as required. Typically, scaling up and scaling out is the norm. The flexible licensing model and cloud-based delivery enable this process.

I never faced any scalability issues.

It is really scalable. It is easy once you get an application in. You can import users from Active Directory and enroll users really fast.

Its scalability is great. There are tons and tons of applications that you can integrate it with. It could become a key piece for the organization for authentication.

There are probably more than 20 customers who are using this solution.

We are a relatively small shop. It was well within our sizing. We never saw any issues with scaling. Obviously, the indications would be that it will scale very well, but nothing we had to experience with.

It is a scalable solution. From what we've seen, it's pretty scalable. It's really good. In terms of when you get an API response, I don't have to keep pulling that endpoint; I just get a response back, which is better than some of the other ones that exist.

The platform is highly scalable, and Duo Security is constantly improving its product; I receive weekly emails about new features and improvements they have made.

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.

This is a very scalable solution. It's not limited to specific applications and we can use it across multiple ones.

We have 175 end-users.

The product is incredibly scalable.

Scalability is there. Our organization is somewhere around 5,000 employees, and that is not very many users for a platform like Duo, so I don't see any issues with scalability.

We have 1,500 users that use Duo Security. We're planning to use Duo Security for more applications, but the number of users won't increase anymore, so in terms of scalability, I don't think we'll have any issues.

When we speak of clients on which Duo Security is deployed, every user in my environment typically has a cell phone and a laptop and we use mobile push. I believe we do use PIN capabilities, as well, but primarily we use mobile push. I suspect that it's on a PC mobile platform.  

We never encountered any issues in terms of scalability. 

I have seen it deployed in an organization with 50 people and another with 5,000 people.

Its scalability is also good. We haven't had any issues expanding it to everything. 

Our company isn't too big. Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow.

The scalability has worked great for us. We've not had any issues with it.

My team gives demonstrations of Duo regularly. The number-one piece of feedback that we get from people is that they like the simplicity. They like the windows, that it's easy to set up, and the features. There are different features and you don't have to turn them all on right away. You can turn on the basic features and get the authentication piece. They like the ability to then drill down and turn on some of those extra features because they don't have to ramp up straight away. They can turn on the basics and be in good shape. Then, if they want to keep tweaking it and turn on all the other pieces, it scales really nicely that way.

End user-wise, we're probably up to about 600 to 700. Our central office is out of Harrisburg, PA and we have a couple of warehouses across the U.S. where I believe they use it too. It's a bit of a distributed model, but it's not a massive distributed model.

Duo Security's scalability is good. We are a fairly large organization but haven't had any scalability issues.

The scalability seems fine. As long as you get the licensing to support it, you can add as many users as you'd like.

We have five or six offices locally, and a few more in different states in the US. We also have one in Shanghai, but they're doing their own thing there. But everyone in our US offices uses it, they all get enrolled. Typically, people will install the app on their phones although they don't have to.

I don't know how Duo would scale. If I've got a hundred websites and I install it on several of them, scalability just means adding it to a new website. It would be as easy as adding it to the first. 

That's not an issue, but I  still haven't figured out how to add new users to a site that already has it installed. I checked their online documentation and haven't found an answer yet,  so we temporarily took it off on that particular site.

After Cisco purchased Duo Security, I was uncertain about its scalability. However, it appears that Cisco has granted them the freedom to pursue their own initiatives and has provided the necessary resources for them to achieve their goals.

It has good scalability.

The scalability is great. The solution is deployed in multiple locations, and we have around 30,000 people.

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.

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

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.

It seems good.

This is a scalable solution. We have 20,000 users covered by this solution. 

It is pretty scalable. We have run it through its paces.

It is scalable and I would rate it 8 out of 10. Regarding the size of your customers, they are mostly large enterprises.

We're a pretty small shop. We have less than 100 employees, so scalability is not a huge concern because there's not a lot of growth right now. However, bundling and provisioning the tool with any device is pretty easy.

I haven't had a deal with that.

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.

It is very scalable. In my company, I have between 90 to 100 users. We also have some users who are working at another site. 

We have plans to increase its usage, but due to COVID, we're mostly working remotely.

The product is very scalable from what I have seen. 

It has scaled to meet our needs. I don't know how it scales if you have 10,000 or 20,000 users, but for our organization, with fewer than 5,000 users, it's been fine.

It can scale to as many employees as you have. It can go from five employees to 1,000 employees. I don't see any issues with the scalability.

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.

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

The scalability is just fine. If you scale a certain amount, you have to upgrade and update your license. Outside of that, it's fine.

We are a large organization that deals with a lot of high transactional payments, and we have a large number of users, maybe 100,000 a day, and inbound user traffic.

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.

The product is scalable - they are in the cloud so scalability is easier.
