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 most valuable aspect is the authentication and the SSO."
"I can say that it is difficult to measure the direct return on investment, but what I can say is that we are safer and feel more comfortable having this security implemented than before."
"The feature I like the most about Cisco Duo is that it allows us to authenticate users before they can connect to our network from outside of our company."
"As a former employee, I think it's top-notch when it comes to protecting internal and external threats and preventing unauthorized access to the network."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"It meets our security needs very well. It is easy to use, and documentation is also available. It is also very stable and scalable, and its support is also very good. We are satisfied with this solution."
"My impression of Cisco's identity intelligence capability to detect and respond to identity-based risks effectively is that it's a great product."
"Multifactor authentication is the most valuable feature."
"The technical support is quite good."
 

Cons

"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."
"Cisco Duo can be improved because people have their own personal mobile devices."
"Cisco Duo did not help reduce the cost of the overall authentication method that we have in our company; instead, it increased, obviously."
"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."
"They could just continue to add more integrations."
"We had some trouble with the password reset function."
"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."
"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."
"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."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"Our licensing fee is currently on an annual basis."
"The pricing was a lot more than what we were paying for our previous solution."
"Cisco has the most expensive products because market leaders tend to charge a lot."
