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

"It is used for SSO, single sign-on, and as a captive portal."
"Intuitive interface and easy to deploy."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"Fulfilled our requirement at a good price."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"Enables easy integration, allowing for 2FA with our VPN."
"Once you configure it properly, it runs fine."
"Silverfort helps identify blind spots in your identity and access management, covering areas that traditional systems don't, such as command line tools."
 

Cons

"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"FortiAuthenticator's interface could be better."
"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."
"The product must provide 2FA for applications."
"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days"
"We've had some issues with integration."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"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 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 platform provides a user-based pricing model rather than a subscription pricing model."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I rate its pricing a three to five out of ten."
