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

"Once you configure it properly, it runs fine."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"We have a perpetual license for 2FA."
"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 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."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"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 technical support for FortiAuthenticator is excellent."
"It's quite scalable."
"The Directory is secure. It's our user store, and it's important to keep our members safe. The product does well with that."
"IWA is an out-of-the-box feature. The SAML-based federation is standard for all tools. However, CA Single Sign-On has made the federation configuration way too simple and handy to set up and use."
"It provides the breadth and the width to provide solutions for the different kinds of technologies which we have."
"Symantec Siteminder has simplified user access for our customers from user login to their web applications."
"That seamless integration significantly improves user experience and efficiency."
"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."
"It is pretty easy to learn."
 

Cons

"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days"
"I would like to see more security features in reference to identity login or identity identification."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"The only way the solution could be improved is if it were cheaper."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability 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."
"There are multiple areas that are in need of improvement. It is not a mature product."
"We would like to the OAuth be more stable, more issues being fixed rather than not."
"I would prefer to see their SAML integration be a more streamlined and easier interface."
"Symantec SiteMinder is not easy to set up and maintain at an infrastructure level."
"I would like to see a move towards the newer technologies, which is what we are doing right now. I think that's in the roadmap that's coming, in the 12.8 and 14 releases, but we would like to have it sooner than later."
"The technical support could be better."
"They need to make configurations easier, and not have the engineer having to guess what will happen when he changes a particular setting."
"Siteminder needs to improve its user experience."
"An area Siteminder could improve on is that there are a few limitations, in terms of new protocols for OpenID. If I want to have different scopes, the features are limited. They also do not have APIs exposed, which is a major drawback. API is a feature I would like to see included in the next release."
 

Pricing and Cost Advice

"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The solution is not very expensive."
"It costs more to license the high-availability option."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"I recommend conducting a PoC on every available product before choose one."
"The solution's pricing is competitive."
"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."
"The pricing is reasonable."
"The price is quite comparable to the other enterprise-level solutions in that market."
"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."
"The licensing is fair for this solution."
