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

"The initial setup is very easy."
"The product's initial setup phase was easy. It is also easy to deploy."
"The two-step authentication provides a higher level of security."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The most valuable features are the performance and ease of use."
"It is very stable. We have never had any issues with this solution."
"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."
"This is a scalable product."
"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

"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"The price of the solution could improve, it is expensive."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"FortiAuthenticator should integrate with other applications."
"We have issues with HA (high availability). These should be addressed in future releases."
"I would like to see more ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
"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."
"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."
"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."
"The shortcomings in the stability need improvement."
 

Pricing and Cost Advice

"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The price seems okay. It's not that expensive compared to other authenticators."
"It costs more to license the high-availability option."
"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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The pricing is fair."
"Users need to pay either annually or on a multi-year basis towards the licensing costs of the product."
