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 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."
"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."
"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."
"We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"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."
"It is really scalable. It is easy once you get an application in. You can import users from Active Directory and enroll users really fast."
"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."
"FortiAuthenticator is a very good solution. It is all jury-based. FortiAuthenticator is very easy for anyone to understand how it works and be able to take action."
"The product’s most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."
"The solution is easy to learn and makes it easy for our users to add FortiToken. It's very easy to integrate if you have other Fortinet devices."
"The product's initial setup phase was easy. It is also easy to deploy."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"I work a lot with Fortinet products and I call the support often. They are very quick to respond and the support is very good."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"Features the addition and removal of access as needed for the VPN."
"The only challenge is finding the right person sometimes. From what I've seen, being a named account is a big deal."
"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."
"Technical support could be improved. I don't think all support should have to go through an agreement."
"The dashboard needs to be improved."
"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."
"They could just continue to add more integrations."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"Sometimes, it's a little harder for customers to adopt."
"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 product must provide full support for third-party FIDO security keys."
"We've had some issues with integration."
"We have issues with HA (high availability). These should be addressed in future releases."
"I would like to see some email options for Fortinet FortiAuthenticator."
"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."
"The GUI has some shortcomings and can be made better. The GUI is not great."
