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

"Once you configure it properly, it runs fine."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"The feature that I have found most valuable is the fact that you can utilize your tokens across the whole Fortinet fabric once you have the FortiAuthenticator."
"The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."
"I work a lot with Fortinet products and I call the support often. They are very quick to respond and the support is very good."
"Technical support is excellent with Fortinet FortiAuthenticator."
"The solution is very easy to manage."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"It has reduced false positives greatly in our fraud detection ability."
 

Cons

"If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So transfer of data and other information should be simpler."
"It can not use SQL to query FortiAnalyzer directly."
"It does the job I paid for, but the graphical interface could be improved."
"For scalability, you need to size FortiAuthenticator properly. It's not 100%, maybe 80% on the scalable side."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"We had some stability issues. Our first LBS unit wouldn't work properly the first time and that wasted a lot of time."
"We've had some issues with integration."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"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."
"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."
"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."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
 

Pricing and Cost Advice

"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"We pay for licensing on a yearly basis."
"The pricing is fair."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"It is usually cheap. Without a license, you can use some basic features. You can buy a 20-year license and implement the solution once."
"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."
"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."
