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

"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"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 logs have great detail that make it easier to evaluate and control the security environment."
"It keeps track of users and their IPs no matter where they are in the network. When users roam, we don't have to worry about not mapping them to an IP."
"The product enables SSO."
"Enables easy integration, allowing for 2FA with our VPN."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"Customer service and support are excellent."
"It has benefited my organization in the way that it makes it more secure by making it harder to hack."
"It provides a service that allows users to sign in to whatever application they are using. This is the most important feature of this solution."
 

Cons

"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days"
"It does not consider customer requirements."
"The user interface and clustering are areas with shortcomings that need improvement."
"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 customization capability of Fortinet FortiAuthenticator is not very flexible."
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"A better integration with other vendors."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"I would like for them to make this solution compatible with Mac OS. I would also like for them to provide a portal so that users can easily integrate it with their applications."
"They should have a landing page."
 

Pricing and Cost Advice

"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"We pay for licensing on a yearly basis."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"It's not expensive."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"At the moment, I believe the price is reasonable."
"The price is reasonable, it's an affordable solution."
