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.

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 product's initial setup phase was easy. It is also easy to deploy."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"FortiAuthenticator is easy to use."
"The solution is easy to learn and makes it easy for our users to add FortiToken. It's very easy to integrate if you have other Fortinet devices."
"We use this product for SSL two-factor authentication and FortiToken management."
"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."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"It reduces the need for network administrator intervention by allowing the user to perform their own registration and resolve their own password problems and issues."
"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 area for improvement in Fortinet FortiAuthenticator is its price."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"It does the job I paid for, but the graphical interface could be improved."
"The product must provide 2FA for applications."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"There is room for improvement in stability and support."
"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 platform provides a user-based pricing model rather than a subscription pricing model."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The solution is not very expensive."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"We pay for licensing on a yearly basis."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The price seems okay. It's not that expensive compared to other authenticators."
