Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

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.

"The current version is stable...Scalability-wise, it is a fine solution"
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"The initial setup is so easy and there is no problem in the implementation."

"Security is the best feature of Microsoft Azure Sentinel."
"The badge reader add-on that allows configuration where a doctor or nurse only has to enter the primary password once per shift is very helpful."

Cons

"One of our clients has faced a lot of issues with FortiAuthenticator. For example, one of the devices restarted by itself, and the database was corrupted."
"I have had stability issues with FortiAuthenticator."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"I would like to see more support from Fortinet with tech support people who have as much expertise on the authenticator as they do on their firewalls."
"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."
"I would like to see more security features in reference to identity login or identity identification."
"The one thing they used to include was the SMS gateway from the ISP; Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back."
"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."
"There were error messages and application actions when the connection to the appliance was disrupted."
"We had some feedback from customers who have said it was a confusing product."
"The shortcomings in the stability need improvement."
 

Pricing and Cost Advice

"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"I price of the solution is expensive."
"We pay for licensing on a yearly basis."
"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."
"The solution is not very expensive."
"Users need to pay either annually or on a multi-year basis towards the licensing costs of the product."
