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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the flexibility in using the SMS messages."
"Fulfilled our requirement at a good price."
"The solution is very easy to manage."
"The product's on-premise version doesn't have recurring costs."
"It is very stable. We have never had any issues with this solution."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"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."
"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."
"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."
"The most valuable feature is the stock tokens. That works the best for us."
 

Cons

"The product must provide 2FA for applications."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"We had issues trying to integrate the keys properly during the initial setup."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"The user interface and clustering are areas with shortcomings that need improvement."
"There is room for improvement in stability and support."
"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."
"The price of the solution could improve, it is expensive."
"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."
"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."
"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 its pricing a three to five out of ten."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"It costs more to license the high-availability option."
"It's not expensive."
"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."
"The product could be more competitively priced."
"The price seems okay. It's not that expensive compared to other authenticators."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"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."
