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

"In my opinion, the best features Cisco Duo offers include its 2FA authentication, which is very good, everything is perfect about the features, it is very easy to use, and the integration with other systems is very good."
"My experience with Cisco Duo's strong security authentication system has been good; it is seamless and easy to integrate, and it is flexible."
"Cisco Duo is very easy to deploy and the documentation is very thorough, which makes deployment straightforward."
"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."
"Cisco Duo is very user-friendly."
"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"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."
"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."
"The technical support is quite good."
 

Cons

"The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers."
"The product price needs improvement."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"Cisco Duo has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"The only issue I encountered was related to the expiration of Duo Unix versions below 2.0.3 on February 3rd."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop."
"Integration with a product such as Microsoft Sentinel would be great."
"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."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"During testing we are allowed a certain number of licenses for free."
"It falls in line with everything else."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"Its price is reasonable. It is not highly expensive."

We switched to Duo Security for identity verification. We’d been using a competitor but got the chance to evaluate Duo for 30 days, and we could not be happier. Duo Security is easy to configure a...
What is your experience regarding pricing and costs for Duo Security?
I cannot speak to the financial planning of the organization, but I can confirm that Cisco Duo falls within the security budget that has been allocated to us.
What needs improvement with Duo Security?
I believe Cisco Duo needs to be improved on the delay process because there is a delay when we send a Duo Push or when we are signing into any applications. We can work on making it faster and spee...
