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.

Offers robustness and ease of use
The product improves our organization's daily healthcare tasks since the use of the tool reduces a lot of support calls, and its users remember many passports that keep on changing. Writing down the passwords somewhere would compromise the security of the system. In our company, the product streamlines access to critical applications and makes it more secure. The management of the system becomes easy with the product. With the product, you can also decide on the strength of the policy you need for your environment. It also helps in the area of authentication credentials. With the product in place, users need to remember fewer passwords, which makes an organization's environment much more secure. The product has improved productivity in the sense that users are now able to manage the tool on their own without having to wait for IT support. IT teams also have to handle fewer support calls and can focus on more value addition in other areas. I recommend the product to others who plan to use it. I suggest that it is always better to use the product's SSO capabilities since it provides security. With SSO capabilities, if you can use multi-factor authentication, you can add a second layer of security to make your system safer and free from attacks. The product's integration capabilities with existing healthcare infrastructure are good. The secure access provided by the product has helped all the applications in our company where security is required. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"FortiAuthenticator is a very good solution. It is all jury-based. FortiAuthenticator is very easy for anyone to understand how it works and be able to take action."
"The most valuable features are the performance and ease of use."
"Enables easy integration, allowing for 2FA with our VPN."
"Features the addition and removal of access as needed for the VPN."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"FortiAuthenticator is easy to use."
"Valuable features include the robust SSO features, when you have more complicated authentication within an organization. We can mix AD, Radius, Portal, SSO Portals (Google, etc.), and build our own environment. It is very flexible."
"Security is the best feature of Microsoft Azure Sentinel. It has its own base security. Our customers like that the security is available in Azure."
"The most valuable features of the solution are its ease of use and its robustness."
 

Cons

"The integration with third-party tools must be better."
"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."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"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."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"We had issues trying to integrate the keys properly during the initial setup."
"I don't have any issues with this solution, but it may need a better, more user-friendly interface or better design of the platform."
"The shortcomings in the stability need improvement."
"We had some feedback from customers who have said it was a confusing product. The product is confusing to use for the end-user. For example, they do not know how to migrate the Azure Sentinel, but others have liked the product that has started working on it."
 

Pricing and Cost Advice

"The price seems okay. It's not that expensive compared to other authenticators."
"I rate its pricing a three to five out of ten."
"The pricing is fair."
"It's not expensive."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"Users need to pay either annually or on a multi-year basis towards the licensing costs of the product."
