Multi-factor security has improved device protection but still needs broader application coverage

Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

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 I find in FortiAuthenticator is web filtering."

"The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."

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

"Valuable features include the robust SSO features, when you have more complicated authentication within an organization. We can mix AD, Radius, Portal, SSO Portals (Google, etc.), and build our own environment. It is very flexible."

"The tool's most valuable features are push notifications and integration with the FortiGate firewall. Push notifications provide an instant acceptance mechanism. When customers try to access SSL VPN, the solution sends a push notification to their mobile phone, and they can easily approve the access. The integration with FortiGate firewall is very easy if our customers use FortiGate for their firewall."

"The solution's most valuable aspect is that it is easy to install and the user experience is very good."

"We have a perpetual license for 2FA."

"The logs have great detail that make it easier to evaluate and control the security environment."

More Fortinet FortiAuthenticator pros

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

"Good support for single sign-on protocols."

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

"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."

"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 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

"It does the job I paid for, but the graphical interface could be improved."

"Fortinet FortiAuthenticator's initial setup process could be easier."

"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"

"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."

"The support team is pathetic and does not properly understand the solution."

"For scalability, you need to size FortiAuthenticator properly. It's not 100%, maybe 80% on the scalable side."

"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."

"There are some protocols, such as SHA and SHA-2, that are not supported."

More Fortinet FortiAuthenticator cons

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

"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."

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

"Security could be improved."

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

Pricing and Cost Advice

"The customers need to pay for licenses, and some pay on a yearly basis while others pay on a three-yearly or five-yearly basis. Also, it is not an expensive solution."

"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."

"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."

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

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

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

More Fortinet FortiAuthenticator pricing and cost advice

"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."

"The license is around $8000 USD."

"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."

"Red Hat Single Sign On is expensive."
