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.

A solution with good capabilities across a wide range of platforms that comes with a useful mobile application, but upgrades cause issues

We have noticed that patches and upgrades cause issues with how the application functions, due to the lack of stability of the product. However, we would recommend the solution because it has good capabilities, across a wide range of platforms, and the mobile application allows for use via Bluetooth, so users don't have to be connected to the internet. I would rate this solution a seven 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 feature of Cisco Duo that I appreciate most is the push notifications. They are great."

"The most valuable feature of Cisco Duo for us is the multi-factor authentication."

"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."

"The feature of Cisco Duo that I value the most is that it's easy to use; it monitors all our devices to ensure everything is updated before we're given access to those applications."

"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."

"Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application."

"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."

"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."

More Cisco Duo pros

"This solution has a mobile application, which comes with multi-factor authentication; allowing for more flexible usage, without having to sacrifice system security."

Cons

"Compared to other vendors, Cisco Duo is on the pricey end."

"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."

"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?""

"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."

"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."

"Certain customers can not use this product because it is cloud-based."

"It is easy to use when logging in, but at times, there's a delay in getting the pop-up on a phone, requiring users to occasionally retry authentication depending on backend services."

"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."

More Cisco Duo cons

"The product suffers from frequent disturbances in service, that have impacted our end users when we deploy software updates."

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

"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."

"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."

"It was very reasonable."

"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."

"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."

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

"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
