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.
"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."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process."
"The solution is easy to use."
"It's pretty easy for users to figure it out."
"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."
"The most valuable feature is the ability for users to connect securely to the office using the VPN."
"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."
"The product is good, cost-effective, and functionally efficient."
"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 logs have great detail that make it easier to evaluate and control the security environment."
"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 most valuable feature of the solution is RADIUS service and the social network integration feature."
"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."
"Sometimes, it's a little harder for customers to adopt."
"There might be a little slowness, but that could be my connection."
"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."
"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix 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."
"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."
"Duo Security could improve by being more compatible with other vendors."
"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."
"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."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"No SMS gateway from the ISP"
"Integration with some other enterprise applications could be improved."
"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."
"The product must provide full support for third-party FIDO security keys."
"I would like to see some email options for Fortinet FortiAuthenticator."
