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

"Cisco Duo is quick to deploy and easy to start."
"Cisco Duo is rock solid in terms of stability and reliability."
"Cisco Duo has made us more secure. We've managed to stop some threats with it and keep our users and devices safe."
"Duo is a very consistent product and flexible in how it can be deployed and has good support."
"I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great."
"From the front end, it's very fast and it hasn't missed a beat, so to say."
"Duo offers dual-factor authentication for our logins; I put in my credentials and hit go, then I get an alert on my Apple Watch and approve it, and that part is just phenomenal."
"Once you break that curve, it gives end users a sense of security where they know that if they're trying to sign on to Office 365 or some other application, they need to authenticate with Duo to make sure that they have the multi-factor authentication."
"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

"I'd like to see it integrated into other applications. I know there are some integrations, but I haven't been able to explore that any further."
"Sometimes, it's a little harder for customers to adopt."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"There might be a little slowness, but that could be my connection."
"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt."
"Duo Security could improve by being more compatible with other vendors."
"We already have Active Directory enabled in our routers and switches. However, if we could do two-factor authentication, then it could go a long way since no one's getting into them unless you want them to."
"If you want easier management, Duo wouldn't meet that need."
"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

"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"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."
"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"During testing we are allowed a certain number of licenses for free."
