Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
Maksym Tkachenko - PeerSpot reviewer

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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 product's initial setup phase was easy. It is also easy to deploy."
"FortiAuthenticator is easy to use."
"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."
"Customer service and support are excellent."
"The technical support for FortiAuthenticator is excellent."
"The most valuable feature is the flexibility in using the SMS messages."
"Simple to deploy, simple to use, and user-friendly."
"It's very fast, and it's easy to use because it's integrated with Active Directory."
"We find that the product scales very well."
"One Identity Defender has good network protection."
 

Cons

"The user interface and clustering are areas with shortcomings that need improvement."
"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."
"If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So transfer of data and other information should be simpler."
"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 think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"The integration with third-party tools must be better."
"The product must provide 2FA for applications."
"There is room for improvement in stability and support."
"The login capabilities could be better."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."
 

Pricing and Cost Advice

"The product could be more competitively priced."
"It costs more to license the high-availability option."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"I rate its pricing a three to five out of ten."
"The pricing is fair."
"It is usually cheap. Without a license, you can use some basic features. You can buy a 20-year license and implement the solution once."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
