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

"FortiAuthenticator is a very good solution. It is all jury-based. FortiAuthenticator is very easy for anyone to understand how it works and be able to take action."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"The current version is stable...Scalability-wise, it is a fine solution"
"FortiAuthenticator centralizes the management and storage of user identity information, thereby increasing the efficiency of administration and increasing the control over who accesses the network."
"We use multi-factor authentication for enhancing security."
"FortiAuthenticator has made our operations secure."
"The most valuable feature is the stock tokens. That works the best for us."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"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."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"It has reduced false positives greatly in our fraud detection ability."
 

Cons

"No SMS gateway from the ISP"
"The product must provide 2FA for applications."
"It does the job I paid for, but the graphical interface could be improved."
"I would like to see support for more credential authentication protocols."
"We have issues with HA (high availability). These should be addressed in future releases."
"The technical support is mid-range; it's not your wow kind of support, and they're not really there when it comes to support."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"If you can't authenticate to protect transactions, and the security is weak, it's a problem."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"It has taken years to implement."
"Reporting modules is one of the major areas that can be improved further."
"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."
"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..."
"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."
 

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 solution is not very expensive."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"It costs more to license the high-availability option."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"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."
"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."
