Featured Reviews

Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

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

"It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"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."
"Technical support is excellent with Fortinet FortiAuthenticator."
"It is very stable. We have never had any issues with this solution."
"This is a very important product if a company wants to use a VPN."
"It is used for SSO, single sign-on, and as a captive portal."
"Enables easy integration, allowing for 2FA with our VPN."
"Silverfort helps identify blind spots in your identity and access management, covering areas that traditional systems don't, such as command line tools."
 

Cons

"I would like to see more security features in reference to identity login or identity identification."
"Lacks a simplified two-factor authentication process."
"I would like to see more security features in reference to identity login or identity identification."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"FortiAuthenticator's interface could be better."
"It does the job I paid for, but the graphical interface could be improved."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"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 cost of the license could be less expensive. The license is paid on a yearly basis."
"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 platform provides a user-based pricing model rather than a subscription pricing model."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"It's not expensive."
"The product has affordable pricing compared to other vendors."
"I rate its pricing a three to five out of ten."
