Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

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 biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The most valuable features are the performance and ease of use."
"Intuitive interface and easy to deploy."
"FortiAuthenticator has helped a lot of our customers in the way that they do the business when they onboard their clients to the data center."
"Technical support is excellent with Fortinet FortiAuthenticator."
"The most valuable feature is the stock tokens. That works the best for us."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"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 capability to manage your business policy related to security when required without vendor involvement."
"It has reduced false positives greatly in our fraud detection ability."
 

Cons

"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"Integration with some other enterprise applications could be improved."
"Their technical staff needs improvement because they take too much time to resolve issues."
"Technical support used to be much better. Fortinet seems to be downgrading, so everything takes longer to get a response in comparison to the past."
"I would like to see more security features in reference to identity login or identity identification."
"The price of the solution could improve, it is expensive."
"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."
"If two-factor authentication is needed also for the end-devices, for example endpoints or servers, I think FortiAuthenticator is not yet the most mature solution."
"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."
"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..."
"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."
"Reporting modules is one of the major areas that can be improved further."
"It's an okay solution. It's just old technology and it's time to move on."
 

Pricing and Cost Advice

"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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"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."
"I rate its pricing a three to five out of ten."
"The solution is not very expensive."
"It costs more to license the high-availability option."
"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."
"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."
