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.

Quotes from Members

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

Cons

"There is room for improvement in stability and support."

"I would like to see some email options for Fortinet FortiAuthenticator."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"I would like to see more security features in reference to identity login or identity identification."
"It can not use SQL to query FortiAnalyzer directly."
"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."
"Reporting modules is one of the major areas that can be improved further."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
 

Pricing and Cost Advice

"It costs more to license the high-availability option."
"We pay for licensing on a yearly basis."
"It's not expensive."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"The solution is not very expensive."

"The product could be more competitively priced."
"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."
"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."
