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

"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"Customer service and support are excellent."
"Enables easy integration, allowing for 2FA with our VPN."
"The product is very easy to use and someone can easily manage working with it, so we do not need any support."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"The logs have great detail that make it easier to evaluate and control the security environment."
"It made things much easier for dealing with users BYOD for our secured wireless networks."
"The ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"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 support from Fortinet with tech support people who have as much expertise on the authenticator as they do on their firewalls."
"FortiAuthenticator should integrate with other applications."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"I would like to see support for more credential authentication protocols."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"We've had some issues with integration."
"Integration with FortiGate could be more fluid."
"Regarding Fortinet technical support, I would say a six. Most of the time, the engineer will take time, such as 24 hours or 48 hours, maybe even more, because most of the time, they appear, gather the logs, and then disappear."
"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 pricing is fair."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The solution is not very expensive."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"It's not expensive."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"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."
"It costs more to license the high-availability option."
