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.

Quotes from Members

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

Pros

"The solution is an integral part of our security for our email network, and like I said, we'll begin using it for other cloud applications."
"The solution is very easy to manage."
"The ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"If you want a more efficient way to manage two-factor authentication for your users, or implement the unit as a cluster member role, the FortiAuthenticator can be incorporated very well into your environment."
"For FortiAuthentication, it's a good price in comparison to any other competitor."
"The most valuable features are the performance and ease of use."
"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 product is very easy to use and someone can easily manage working with it, so we do not need any support."
"Lifecycle management, governance and documentation."
"This solution has a very good dashboard and the documentation is also very good, and life cycle management and governance are also good features in this solution."
"We use the product to ensure organizations conform to industry base certifications and best practices and do not contradict their security policies within the base points they specify in the system, which are used to match everything against their governance use cases."
"I would rate the price eight out of 10, with 10 as the best value for money."
 

Cons

"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."
"There are some issues with integration."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"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."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days."
"The integration with other products, for example, some SAML authentications, would make it more flexible."
"A better integration with other vendors."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"The solution is a bit pricey for some regions."
"I think improvements could be made in the self service center, making it easier for the user to understand."
"The solution is also a bit pricey for the Nigeria region."
"Self service center is not always easy to understand."
 

Pricing and Cost Advice

"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 platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"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."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I would rate the price eight out of 10, with 10 as the best value for money."
