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 initial setup is so easy and there is no problem in the implementation."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"Using this product strengthens enterprise security."
"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 solution is an integral part of our security for our email network, and like I said, we'll begin using it for other cloud applications."
"Technical support is excellent with Fortinet FortiAuthenticator."
"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."
"I really like the two-step authentication, it provides a higher level of security that we didn't have previously."
"The most valuable feature is the stock tokens. That works the best for us."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"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."
 

Cons

"There are some protocols, such as SHA and SHA-2, that are not supported."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available."
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"A better integration with other vendors."
"The only way the solution could be improved is if it were cheaper."
"I would like to see more security features in reference to identity login or identity identification."
"One of our clients has faced a lot of issues with FortiAuthenticator. For example, one of the devices restarted by itself, and the database was corrupted."
"It's an okay solution. It's just old technology and it's time to move on."
"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."
"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."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
 

Pricing and Cost Advice

"It's not expensive."
"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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I price of the solution is expensive."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"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."
"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."
"The pricing is $50 per head, yearly."
"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."
