Featured Reviews

Yonas Abebe - PeerSpot reviewer
Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
Muzi Lubisi - PeerSpot reviewer
Improved user experience with seamless integration and easy installation
The feature that I mostly valued is the ease of installation on different systems, especially on Windows. Additionally, it is very beneficial for deploying single sign-on sessions between different windows on a web browser, provided I am connected to the right identity provider. That seamless integration significantly improves user experience and efficiency.

Quotes from Members

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

Pros

"The current version is stable...Scalability-wise, it is a fine solution"
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The product enables SSO."
"Enables easy integration, allowing for 2FA with our VPN."
"You can quickly deploy the entire product with a basic config within couple of hours."
"Siteminder allows us to manage identity and portability control efficiently."
"SAML is the best thing we're using right now because there is no need for creating an external account."
"Siteminder allows us to manage identity and portability control efficiently."
"It has the ability to authenticate and authorize users. It is the main feature for our security."
"If you look at our organization, and really all financial institutions, we have a lot of legacy apps. So it really helps to get Single Sign-On."
"The authentication and single sign-on features of Symantec Siteminder are valuable."
"All of our applications get a point, click, and you are in, while we increase security at the same time."
 

Cons

"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"There are multiple areas that are in need of improvement. It is not a mature product."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"I would like to see more security features in reference to identity login or identity identification."
"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."
"FortiAuthenticator should integrate with other applications."
"The user interface and clustering are areas with shortcomings that need improvement."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"We would like to the OAuth be more stable, more issues being fixed rather than not."
"The tech support has not been very good for us so we don't use them anymore. We have had some issues. Nobody is perfect."
"I'd like to see a rework of the user directory configuration."
"The support team could work on their response time and overall competence."
"The technical support could be better."
"In future releases, I would like to see maybe more capabilities with some more modern authentication."
"To add more value to this solution it needs to be more user-friendly."
"I think they need to integrate some of the newer types of authentication into the product. I'm not seeing the innovation when it comes to biometrics in the product."
 

Pricing and Cost Advice

"I rate the price of Fortinet FortiAuthenticator a three out of five."
"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."
"The product could be more competitively priced."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The pricing is fair."
"I rate its pricing a three to five out of ten."
"I price of the solution is expensive."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The solution's pricing is competitive."
"I recommend conducting a PoC on every available product before choose one."
"The price is quite comparable to the other enterprise-level solutions in that market."
"The licensing is fair for this solution."
"The pricing is reasonable."
"CA solutions are generally expensive but for the customer the ROI is big."
"Symantec Siteminder is expensive; they could definitely do better on the price."
"Siteminder is a little costly. You pay for licensing, and they offer packages, so if you have less users, then you have to buy different products at different prices. If you have more of a user base, then the package is different. They also include other features—for example, if you have a database and you're using Siteminder, then it's good to use a Semantic-specific database, but if you are using less, then you have to purchase the database separately. Whereas if you are going for a bigger license, then it comes within the package. It depends on which plan you are using."
