We performed a comparison between Duo Security and Fortinet FortiAuthenticator based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Users of both solutions would like more integration options.
Comparison Results: Duo Security is the winner in this comparison. It received high marks for its ease of deployment and support. In contrast, some FortiAuthenticator users say that the initial setup is complex and feel that the support needs to improve.
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"The ability for users to authenticate via phone, from any random phone number, has been very helpful for managing a distributed workforce. Using it across a distributed network for securing access to our applications is big for us."
"The integration with Azure Active Directory and the AWS cloud is amazing, as most products nowadays require the creation of a customized integration. With Duo Security, it was more like native integration, and it took me five minutes to register."
"I like the set time that users can log into devices during the day and how many times they can do so. I also like the ability to restrict the regions from which the user can get in. Users outside of our country or even the town cannot log in."
"The two-factor login is great. I receive a message and just have to press okay."
"It's pretty easy for users to figure it out."
"The single pane of glass management is very important and it is part of the reason we went with Duo. Anything we can do to save time for our administrators, help desk staff, and engineers, is valuable to us."
"It is a good solution for hybrid environments and VPN."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"Enables easy integration, allowing for 2FA with our VPN."
"The solution is very easy to manage."
"The product's initial setup phase was easy. It is also easy to deploy."
"It reduces the need for network administrator intervention by allowing the user to perform their own registration and resolve their own password problems and issues."
"The most valuable feature is the flexibility in using the SMS messages."
"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"Duo has some issues that we're trying to work through. For example, if I install it on a WordPress site and another admin needs to log in, they can't because Duo hasn't been set up for them. It doesn't appear that I can add permissions on a user-by-user basis. It's not obvious."
"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."
"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."
"I'm not a big fan of relicensing products every year or two years, but that's the model at the moment. I prefer to go back to licensing perpetually or permanent licensing."
"I would appreciate it if Duo Security could improve its integrations with Windows Hello."
"They could just continue to add more integrations."
"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."
"The only issue I encounter is that when not using FortiAuthenticator for an extended period, it's typical to encounter some obstacles in the configuration process that you need to address."
"I would like to see some email options for Fortinet FortiAuthenticator."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"The only way the solution could be improved is if it were cheaper."
"The product must provide 2FA for applications."
"I would like to see more ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
