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.

"The solution is very easy to manage."
"The integration into tools, including CI/CD pipelines, is easy and handy."

"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."
"The capability to manage your business policy related to security when required without vendor involvement."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
 

Cons

"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."
"We would like to see Linux-based operating systems be able to integrate with FortiAuthenticator to get two-factor authentication running on them. as well. This is a shortcoming that I have faced a few times already."
"Integration with FortiGate could be more fluid."
"We've had some issues with integration."
"The product must provide full support for third-party FIDO security keys."
"The only way the solution could be improved is if it were cheaper."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"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."

"Reporting modules is one of the major areas that can be improved further."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
 

Pricing and Cost Advice

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