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 solution's most valuable aspect is that it easy to install. The user experience is very good."
"The product's initial setup phase was easy. It is also easy to deploy."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"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."
"Fortinet FortiAuthenticator is an easy-to-use solution."
"Once you configure it properly, it runs fine."
"The logs have great detail that make it easier to evaluate and control the security environment."
"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

"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"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."
"We have issues with HA (high availability). These should be addressed in future releases."
"The product must provide full support for third-party FIDO security keys."
"There is room for improvement in stability and support."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"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 its pricing a three to five out of ten."
"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 product could be more competitively priced."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The product has affordable pricing compared to other vendors."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"Users need to pay either annually or on a multi-year basis towards the licensing costs of the product."
