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.

We need better ease of use; the product is overly complicated
There are many use cases that we have defined based on our business needs Ingestion of logs and raising alert space on those logs are the most valuable features. The product is basically unusable. We need better ease of use; it's overly complicated. It has taken years to implement. We used RSA…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product is stable and reliable."
"We are using Fortinet FortiAuthenticator to implement token-based authentication for wireless network access."
"The most valuable feature is the flexibility in using the SMS messages."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The initial setup of Fortinet FortiAuthenticator is easy."
"This is a scalable product."
"The logs have great detail that make it easier to evaluate and control the security environment."
"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 capability to manage your business policy related to security when required without vendor involvement."
"Our customer are seeing value from the product, as they experience cost reductions. They can stop fraud from their customers, then their customers can have a better experience from their services."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"The most valuable feature is the stock tokens. That works the best for us."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
 

Cons

"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"Integration with some other enterprise applications could be improved."
"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."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"The product must provide 2FA for applications."
"The only issue I encounter is that when not using FortiAuthenticator for an extended period, it's typical to encounter some obstacles in the configuration process that you need to address."
"Reporting modules is one of the major areas that can be improved further."
"It has taken years to implement."
"Better filters when searching for events. The current features for current filters when searching fraud events are not very comprehensive. You can only filter by certain fields in the transaction."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"The product is basically unusable. We need better ease of use; it's overly complicated."
 

Pricing and Cost Advice

"You can pay as you go with them. You purchase a base license and add to it as needed."
"I price of the solution is expensive."
"I rate its pricing a three to five out of ten."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The solution is not very expensive."
"The price seems okay. It's not that expensive compared to other authenticators."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"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."
"Customers need to deploy the solution in a very expensive infrastructure. RSA should should think about a less expensive infrastructure for customers because the solution costs around $100,000, and the infrastructure needed to support that solution may be even more expensive than that price."
"You may need to opt for second best if funding is low and the number of users is huge. However, the pricing is able to be negotiated if your user figures are huge."
"The pricing is $50 per head, yearly."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
