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

"We use multi-factor authentication for enhancing security."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"It is used for SSO, single sign-on, and as a captive portal."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The current version is stable...Scalability-wise, it is a fine solution"
"The tool's most valuable features are push notifications and integration with the FortiGate firewall. Push notifications provide an instant acceptance mechanism. When customers try to access SSL VPN, the solution sends a push notification to their mobile phone, and they can easily approve the access. The integration with FortiGate firewall is very easy if our customers use FortiGate for their firewall."
"The initial setup is so easy and there is no problem in the implementation."
"This was a regulation we needed to fill and it worked at a good price."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"It has reduced false positives greatly in our fraud detection ability."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"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."
 

Cons

"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"There are multiple areas that are in need of improvement. It is not a mature product."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"No SMS gateway from the ISP"
"The one thing they used to include was the SMS gateway from the ISP; Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back."
"It does not consider customer requirements."
"I would like to see support for more credential authentication protocols."
"For scalability, you need to size FortiAuthenticator properly. It's not 100%, maybe 80% on the scalable side."
"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."
"It has taken years to implement."
"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..."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
 

Pricing and Cost Advice

"The solution is not very expensive."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The product has affordable pricing compared to other vendors."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"It costs more to license the high-availability option."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"We pay for licensing on a yearly basis."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"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."
