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.

Quotes from Members

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

Pros

"It is very stable. We have never had any issues with this solution."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"The product is stable and reliable."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"The current version is stable...Scalability-wise, it is a fine solution"
"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."
"It's very fast, and it's easy to use because it's integrated with Active Directory."
"We find that the product scales very well."
"One Identity Defender has good network protection."
 

Cons

"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"The user interface and clustering are areas with shortcomings that need improvement."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"The login capabilities could be better."
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."
 

Pricing and Cost Advice

"You can pay as you go with them. You purchase a base license and add to it as needed."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I price of the solution is expensive."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"The pricing is fair."
"The solution is not very expensive."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"The platform provides a user-based pricing model rather than a subscription pricing model."
