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.

Positive feedback highlights lightweight design and compatibility while suggesting more AI integration
Silverfort helps identify blind spots in your identity and access management, covering areas that traditional systems don't, such as command line tools. It checks your Active Directory authentication and continues only if the check is okay, plus it works with older protocols such as NTLM, which is a significant advantage. It's complementary to other tools you may have, whether they are TAM solutions such as Delinea or Xerox. Silverfort also has a lightweight adapter for domain controllers, and it finds gaps in security. Its capabilities are expanding regularly, with new features voted on every few months. For companies with large Active Directory implementations and zero staff, Silverfort provides instant results in identifying risks and blind spots. It also includes built-in virtual features, and while I don't know the exact pricing, it's not expensively priced, making it an attractive option.

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 features are the performance and ease of use."
"I work a lot with Fortinet products and I call the support often. They are very quick to respond and the support is very good."
"It is used for SSO, single sign-on, and as a captive portal."
"Simple to deploy, simple to use, and user-friendly."
"We use multi-factor authentication for enhancing security."
"The current version is stable...Scalability-wise, it is a fine solution"
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"Silverfort helps identify blind spots in your identity and access management, covering areas that traditional systems don't, such as command line tools."
 

Cons

"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"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."
"The only way the solution could be improved is if it were cheaper."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"The area for improvement in Fortinet FortiAuthenticator is its price."
"The price of the solution could improve, it is expensive."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"If Silverfort could integrate a gentle type of AI similar to Microsoft Copilot or enable workflow creation similar to Salesforce, it would further improve user navigation, even though the platform is already simple."
 

Pricing and Cost Advice

"The price seems okay. It's not that expensive compared to other authenticators."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"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."
"It is usually cheap. Without a license, you can use some basic features. You can buy a 20-year license and implement the solution once."
"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."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The platform provides a user-based pricing model rather than a subscription pricing model."
