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
Owner at Syntlogo GmbH
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 most valuable feature is the flexibility in using the SMS messages."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"Using this product strengthens enterprise security."
"For FortiAuthentication, it's a good price in comparison to any other competitor."
"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."
"The product enables SSO."
"Enables easy integration, allowing for 2FA with our VPN."
"We use this product for SSL two-factor authentication and FortiToken management."
"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."
"I like that the solution is open source and you can use a commercial edition of it without any charge."
"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."
"Red Hat SSO has a lot of very concise, well laid out documentation, which is available in the free edition as well."
 

Cons

"We had issues trying to integrate the keys properly during the initial setup."
"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."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"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."
"Their technical staff needs improvement because they take too much time to resolve issues."
"We would like to see Linux-based operating systems be able to integrate with FortiAuthenticator to get two-factor authentication running on them. as well. This is a shortcoming that I have faced a few times already."
"It does the job I paid for, but the graphical interface could be improved."
"I think the tool could provide this solution on the cloud."
"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."
"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. Some other products have these detection mechanisms in case someone is trying to hack into the system or find out a user's passwords."
"Security could be improved."
"I think they could provide additional features in terms of users trying to manipulate the system with regard to security."
 

Pricing and Cost Advice

"The solution is not very expensive."
