Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

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 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."
"It made things much easier for dealing with users BYOD for our secured wireless networks."
"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"It is very stable. We have never had any issues with this solution."
"In my opinion, the main benefits that end users receive from Fortinet FortiAuthenticator include more security for their applications, for their systems, and for all their network devices that they are logging into."
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"The most valuable features are the performance and ease of use."
"Fulfilled our requirement at a good price."
"It has reduced false positives greatly in our fraud detection ability."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"The capability to manage your business policy related to security when required without vendor involvement."
"The most valuable feature is the stock tokens. That works the best for us."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
 

Cons

"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"The integration with third-party tools must be better."
"The one thing they used to include was the SMS gateway from the ISP; Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back."
"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."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"The interface is a bit misleading in areas."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"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."
"It has taken years to implement."
"Reporting modules is one of the major areas that can be improved further."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"I think I would like to see them use more of our data, and give us more ability to control or configure how the protection patterns work for a specific business, and also provide more transparency into the methodology."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"It's an okay solution. It's just old technology and it's time to move on."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
 

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 costs more to license the high-availability option."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"I price of the solution is expensive."
"The pricing is fair."
"The solution is not very expensive."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"The pricing is $50 per head, yearly."
