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

"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."
"The feature of Cisco Duo that I appreciate most is the push notifications."
"I can recommend Cisco Duo because it is very easy to accept and understand."
"My advice for other companies that are considering getting Cisco Duo is to try it, and you will be amazed at how easy and how productive this tool is."
"What I appreciate the most is that you can push a notification with your phone and log in to your computer."
"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."
"Regarding the stability and reliability of Cisco Duo, it is very good."
"The feature I like the most about Cisco Duo is two-factor authentication, as it helps me to defend against phishing attacks and provides security for my organization."
"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

"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."
"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."
"Regarding the stability and reliability of the Cisco Duo solution, we have experienced some outages over the last few years that are significant because people can't log in."
"Areas that have room for improvement in Cisco Duo include pricing, as Cisco is quite expensive, and the fact that Cisco Duo relies heavily on external identity providers such as Active Directory or Entra ID and does not offer full identity lifecycle management on its own, which leads organizations to often pair Cisco Duo with another IAM solution for complete identity governance."
"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop. Other than that, the solution was rock solid throughout my time administering it."
"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."
"Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system."
"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

"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"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."
"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."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt 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 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."
