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

"Duo features benefit my company by making logins more secure and simpler. Everything is in one box, so we don't have multiple servers trying to do the same thing."
"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."
"Cisco Duo just works; that is the best feature."
"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."
"The most valuable feature of Cisco Duo for us is the multi-factor authentication."
"Cisco Duo is quick to deploy and easy to start."
"The features of Cisco Duo have benefited my organization because it's secure, provides a way of accessing the workspace, and it's easy to operate from mobile."
"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies."
"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

"We use Yubikey for pushing it to the phones. Yubikeys can get expensive because people tend to lose those for some reason. Fifty dollars a device is pretty high."
"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."
"For the back-end, there could be a few more security features applied."
"The only issue I encountered was related to the expiration of Duo Unix versions below 2.0.3 on February 3rd."
"There is a little bit of apprehension for some users thinking, well, "How do I know this app is not collecting personal information from my personal device?""
"Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches."
"One issue I see is when the device is offline."
"There might be a little slowness, but that could be my connection."
"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

"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"It was very reasonable."
"The product’s pricing is reasonable."
"It falls in line with everything else."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"Duo Security's pricing is good, fair, and very comparable to today's market."
