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.
"The flexibility is the most valuable feature. We use it for the app on the phone. When we're at different locations, the phone is usually there, so we can use that. It has just been a very flexible option."
"It provides single-pane-of-glass management, which is pretty easy and straightforward. Because we manage multiple access tiers, it allows us to essentially manage everything from one viewpoint and not have many viewpoints for the same product. This is important because it is a time and resource saver. It also saves us money."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"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."
"Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow."
"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."
"It's pretty easy for users to figure it out."
"Intuitive interface and easy to deploy."
"FortiAuthenticator is easy to use."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"The most valuable feature is the OTP on the mobile phone."
"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."
"The two-step authentication provides a higher level of security."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"The technical engineers in the first line of support should improve their knowledge."
"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."
"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"The new smart license model doesn't always work. It's very complicated."
"There might be a little slowness, but that could be my connection."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"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."
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"We've had some issues with integration."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"I would like to see some email options for Fortinet FortiAuthenticator."
"The user interface and clustering are areas with shortcomings that need improvement."
"Integration with some other enterprise applications could be improved."
