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

"For me and my customers, the best feature is that it's very easy to integrate with the existing infrastructure. It takes a few minutes to configure it."
"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."
"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."
"With respect to our users feeling safe, secure, supported, and included, Duo Security is among the best solutions that we have ever used."
"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."
"I can recommend Cisco Duo because it is very easy to accept and understand."
"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."
"I appreciate the secured push feature of Cisco Duo, which requires you to choose a number, because it enhances the security of your users, especially when combined with geolocation for a Verified Push, benefiting my company and our customers by making logins much more secure."
"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

"Duo Security should better organize its tile feature to organize applications better."
"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."
"If you want easier management, Duo wouldn't meet that need."
"Cisco Duo can be improved because people have their own personal mobile devices."
"One area that might be improved is that setting up SMS texting is not as easy as using the app, even though it does support it."
"An AI support robot or bot that provides direct answers to questions without requiring the search for facts or documents to find solutions would be an improvement."
"They could just continue to add more integrations."
"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

"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"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."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"Duo Security is free."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"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."
