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 most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."
"It keeps track of users and their IPs no matter where they are in the network. When users roam, we don't have to worry about not mapping them to an IP."
"Enables easy integration, allowing for 2FA with our VPN."
"The technical support for FortiAuthenticator is excellent."
"We have not had issues with Fortinet FortiAuthenticator. It is stable."
"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 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."
"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

"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So transfer of data and other information should be simpler."
"The technical support team is bad."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"Lacks a simplified two-factor authentication process."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"The price of the solution could improve, it is expensive."
"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 licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"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."
"It costs more to license the high-availability option."
"The product could be more competitively priced."
"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 solution is not very expensive."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The platform provides a user-based pricing model rather than a subscription pricing model."
