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.

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

"We have not had issues with Fortinet FortiAuthenticator. It is stable."
"FortiAuthenticator is easy to use."
"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 prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"We use multi-factor authentication for enhancing security."
"The most valuable feature is the OTP on the mobile phone."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"The most valuable feature is the stock tokens. That works the best for us."
"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."
 

Cons

"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"The only way the solution could be improved is if it were cheaper."
"The integration with third-party tools must be better."
"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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"It has taken years to implement."
"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."
 

Pricing and Cost Advice

"We pay for licensing on a yearly basis."
"It costs more to license the high-availability option."
"I price of the solution is expensive."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"It's not expensive."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"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."
"The price seems okay. It's not that expensive compared to other authenticators."
"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."
"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."
