Supports seamless authentication for users across multiple organizations and personal portals
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.

Easy to use, reliable, and offers a straightforward setup
We are customers and end-users. We've dealt with the solution for a long time. We've seen how they developed as a startup, and how they've matured over time. They're actually quite advanced and they are sometimes cutting edge compared to other competitors. I'd recommend the solution. They do things very differently. They're very advanced and they're standards-based. They basically have got a very good vision in terms of how they do strong authentication. Other companies are actually following suit and following what they've done to support standards. They're quite advanced and simple to use, with a good support model. They have the edge compared to other solution providers. In general, I would rate the solution at an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The flexibility is the most valuable feature. We use it for the app on the phone. When we're at different locations, the phone is usually there, so we can use that. It has just been a very flexible option."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"My advice for other companies that are considering getting Cisco Duo is to try it, and you will be amazed at how easy and how productive this tool is."
"The most valuable aspect is the authentication and the SSO."
"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."
"It's pretty easy for users to figure it out."
"The technical support is quite good."
"They are sometimes cutting edge compared to other competitors and have a very good vision in terms of how they do strong authentication, being quite advanced, simple to use, and standards-based with a good support model, giving them an edge compared to other solution providers."
 

Cons

"The product price 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. 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."
"Duo Security should better organize its tile feature to organize applications better."
"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with M365, so everyone is switching to that and using it instead of Cisco Duo because it costs extra as a standalone product."
"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"At the moment, I believe that more integration between Cisco Duo Identity Intelligence and the classic Cisco Duo console can be improved, since it is still a separate platform, and when I click on Identity Intelligence, I have to open a new window and log in again."
"Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system."
"Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them."
"There's nothing wrong with the solution that we can see. However, maybe they could improve slightly by incorporating decentralized identity blockchain models into their solution."
 

Pricing and Cost Advice

"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."
"It was very reasonable."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"During testing we are allowed a certain number of licenses for free."
"Our licensing fee is currently on an annual basis."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"It falls in line with everything else."
"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."
