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
I think Silverfort is actually a really good product. 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. The product is fairly new, but it's great; it's lightweight and agent-based, acting as a bridge between your Active Directory and any other application, with no impact on the applications. Silverfort is one of the few vendors that offers a free POC, and usually the customer ends up taking it, as they've lost very few deals in this manner. 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 tool's most valuable features are push notifications and integration with the FortiGate firewall. Push notifications provide an instant acceptance mechanism. When customers try to access SSL VPN, the solution sends a push notification to their mobile phone, and they can easily approve the access. The integration with FortiGate firewall is very easy if our customers use FortiGate for their firewall."
"Enables easy integration, allowing for 2FA with our VPN."
"FortiAuthenticator has made our operations secure."
"I am really impressed by the technical support because they were very helpful; once we logged our complaint, we received an answer from them in no time, and they quickly fixed our issue."
"Fulfilled our requirement at a good price."
"It made things much easier for dealing with users BYOD for our secured wireless networks."
"The feature that I have found most valuable is the fact that you can utilize your tokens across the whole Fortinet fabric once you have the FortiAuthenticator."
"The most valuable feature is the OTP on the mobile phone."
"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 ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
"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 some issues with integration."
"The integration with other products, for example, some SAML authentications, would make it more flexible."
"The area for improvement in Fortinet FortiAuthenticator is its price."
"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."

"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"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."
"The pricing is fair."
