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 most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."
"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."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"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."
"The most valuable feature is the flexibility in using the SMS messages."
"We are using Fortinet FortiAuthenticator to implement token-based authentication for wireless network access."
"Customer service and support are excellent."
"This is a scalable product."
"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 product must provide full support for third-party FIDO security keys."
"The price of the solution could improve, it is expensive."
"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."
"It does not consider customer requirements."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"No SMS gateway from the ISP"
"I would like to see more security features in reference to identity login or identity identification."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"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

"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"It's not expensive."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"It costs more to license the high-availability option."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
