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.

Quotes from Members

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

Pros

"FortiAuthenticator is easy to use."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"We have a perpetual license for 2FA."
"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."
"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 product enables SSO."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The product’s most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."
"We find that the product scales very well."
"One Identity Defender has good network protection."
"It's very fast, and it's easy to use because it's integrated with Active Directory."
 

Cons

"Integration with some other enterprise applications could be improved."
"Integration with FortiGate could be more fluid."
"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 product must provide 2FA for applications."
"The technical support team is bad."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"The login capabilities could be better."
"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

"It's not expensive."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"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 platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
