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.

A stable and flexible solution with some basic capabilities

I set up Red Hat Single Sign-On in half an hour. I had to install a single sign-on solution for a customer. I reviewed a list of all available products, which were no more than fifty, and analyzed them. I chose it because it was convincing, modern, and based on technology from 2015. I put my trust in this product, and after nine years, I feel confident in my decision. Deploying this solution usually takes half an hour. You need an operating system running, then deploy the packages and prepare the interfaces. I rate the initial setup a ten out of ten, where one is difficult and ten is easy.

Quotes from Members

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

Pros

"The feature that I have found most valuable is the fact that you can utilize your tokens across the whole Fortinet fabric once you have the FortiAuthenticator."

"For FortiAuthentication, it's a good price in comparison to any other competitor."

"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."

"FortiAuthenticator has created a straightforward easy-to-use product."

"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."

"This is a cost effective and flexible solution."

"The most valuable feature I find in FortiAuthenticator is web filtering."

"The solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."

More Fortinet FortiAuthenticator pros

"Red Hat SSO has a lot of very concise, well laid out documentation, which is available in the free edition as well."

"Red Hat SSO integrates well with our other solutions. Using OIDC protocols and ITL integration, employees can authenticate with Red Hat SSO and access our microservices."

"It is very easy to scale and use as you want."

"I like that the solution is open source and you can use a commercial edition of it without any charge."

"The product’s most valuable feature is its ability to assign only one password for the user at a false value."

"Good support for single sign-on protocols."

"The solution is flexible and has the same basic capabilities right out of the box. The most important feature of this product is that it is a Red double-sided product. One side is a well-known open-source project; the other is a Red Hat commercial product. The commercial product benefits from all the experience and contributions of the community, making it a very well-developed product."

Cons

"Technical support used to be much better. Fortinet seems to be downgrading, so everything takes longer to get a response in comparison to the past."

"I would like to see more security features in reference to identity login or identity identification."

"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."

"The integration with third-party tools must be better."

"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."

"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."

"The GUI has some shortcomings and can be made better. The GUI is not great."

"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."

More Fortinet FortiAuthenticator cons

"Red Hat SSO's architecture could be updated."

"They could provide more checks and balances to find out if there have been any security lapses, e.g., if somebody is trying to break into the system."

"They could provide more checks and balances to find out if there have been any security lapses, e.g., if somebody is trying to break into the system. Some other products have these detection mechanisms in case someone is trying to hack into the system or find out a user's passwords."

"I think they could provide additional features in terms of users trying to manipulate the system with regard to security."

"Red Hat publishes much more and communicates its actions and plans. They could provide words, maps, and other resources."

"The product’s technical support services could be better."

"Security could be improved."

Pricing and Cost Advice

"The cost of the license could be less expensive. The license is paid on a yearly basis."

"It costs more to license the high-availability option."

"The product has affordable pricing compared to other vendors."

"We pay for licensing on a yearly basis."

"I rate its pricing a three to five out of ten."

"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."

"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."

"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."

More Fortinet FortiAuthenticator pricing and cost advice

"Red Hat Single Sign On is expensive."

"The license is around $8000 USD."

"It is a low cost product. This product can be used by non-profit organizations or universities, when they don't want to invest a lot of money."

"If you want support, that is when you use the paid version. There are different support categories that you can pay for, which provide different support levels. E.g., there is a quick response if you pay a higher amount, where the response time is within a few hours."

Overview

Fortinet FortiAuthenticator is the primary secure point of approved access into the Fortinet network, authorizing users, reviewing access permissions, and relaying the information to all Fortigate devices for comparison with identity-based protocols. Fortinet FortiAuthenticator is a top-ranked authorization and SSO solution.

Appropriate secure access is fundamental to every role in an enterprise ecosystem. It is an integral function of every organization to ensure that every access and privilege is secure and to mitigate any possible risk to an organization. Approved users should only have access to the necessary information when they need it, from the appropriate location(s) to safeguard an organization's security at all times.

Fortinet FortiAuthenticator is available as an appliance, virtual machine, or in the cloud.

Fortinet FortiAuthenticator Methods

FSSO: FortiAuthenticator Single sign-on user will easily identify users and assign role or group access based on preset identity-based protocols. FortiAuthenticator integrates well with third-party LDAP or active directories, is very flexible, and combines these methods to provide effective security.
Active Directory Polling: Active directory access is securely identified by consistent polling of domain controllers. As users log in, username, IP address, and other details are logged into the database and can be shared across devices as directed by FortiAuthenticator protocols.
FortiAuthenticator Portal and Widgets: If a user system does not support AP polling, or for other reasons it is not feasible, FortiAuthenticator offers a unique secure authentication portal. Users can be manually authenticated and, to diminish the effect of numerous logins, an intuitive set of widgets is available to integrate into an organization's ecosystem that will automatically grant access to users when they access the organization's intranet homepage.
RADIUS Accounting Login: For organizations that use RADIUS authentication, RADIUS Accounting is available for user identification. This process will prompt user access information (IP and group, etc.) and eliminate the need for multiple levels of authentication.
