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.
"It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work."
"Multifactor authentication is the most valuable feature."
"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."
"I lead an IT organization that has a significant amount of technical debt, and we're not in a zero-trust architecture yet. I'm pushing in that direction. Duo helps me considerably with my identity in an environment where I don't have zero trust. It's helping me bridge the gap until I can build a zero trust architecture."
"It has definitely reduced embedding. We found a lot of problems with attackers being able to compromise accounts. Now, when they try to access accounts, they are not able to do so because there is an added layer of protection. Once we know that a username and password are compromised, we just reset the password to protect the company."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"The most valuable features of Duo Security are visibility and OTP authentication. The OTP is very important because it is a self-enrollment feature, you are able to enroll users very quickly with a shorter time period."
"The two-factor authentication is valuable because that is the use case for which we are using it."
"The initial setup is very easy."
"Features the addition and removal of access as needed for the VPN."
"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."
"FortiAuthenticator is easy to use."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"Enables easy integration, allowing for 2FA with our VPN."
"The product is stable and reliable."
"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."
"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."
"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."
"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 Security should have more customized use cases. For example, if a client needs to have more customization, it would be better to connect directly with Duo's R&D to try to discuss the issues together in order to add customizations."
"There might be a little slowness, but that could be my connection."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"I would appreciate it if Duo Security could improve its integrations with Windows Hello."
"FortiAuthenticator's interface could be better."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"We have issues with HA (high availability). These should be addressed in future releases."
"A better integration with other vendors."
"Lacks a simplified two-factor authentication process."
"There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
