Featured Reviews

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.
Giovanni Baruzzi - PeerSpot reviewer

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 solution's most valuable aspect is that it is easy to install and the user experience is very good."
"The response from Fortinet is very fast."
"The solution is very easy to manage."
"The product's initial setup phase was easy. It is also easy to deploy."
"The initial setup is very easy."
"Once you configure it properly, it runs fine."
"Features the addition and removal of access as needed for the VPN."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"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."
"The product’s most valuable feature is its ability to assign only one password for the user at a false value."
"I like that the solution is open source and you can use a commercial edition of it without any charge."
"Good support for single sign-on protocols."
"It is very easy to scale and use as you want."
"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."
"Red Hat SSO has a lot of very concise, well laid out documentation, which is available in the free edition as well."
 

Cons

"There are some protocols, such as SHA and SHA-2, that are not supported."
"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."
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"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."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"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."
"Red Hat SSO's architecture could be updated."
"Security could be improved."
"I think they could provide additional features in terms of users trying to manipulate the system with regard to security."
"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."
"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."
 

Pricing and Cost Advice

"We pay for licensing on a yearly basis."
"I price of the solution is expensive."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"It's not expensive."
"The price seems okay. It's not that expensive compared to other authenticators."
"It costs more to license the high-availability option."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The license is around $8000 USD."
"Red Hat Single Sign On is expensive."
"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."
"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."
