Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

A flexible solution that has two-factor authentication feature
The solution has been integrated into our mobile workforce using SAP IAS. This service links all SAP products with a central authentication platform, allowing users to access various systems and functionalities. We can easily integrate this solution with Active Directory or other solutions such as Microsoft or IBM. Additionally, SAP IAS also supports digital authentication, not only for SAP but also for other platforms like Microsoft Azure. Customers can quickly establish user authentication with SAP IAS in just a few minutes, enabling secure access to specific products or systems based on predefined rules. The two-factor authentication feature of SAP Single Sign-On is highly valuable for enhancing security. It allows users to access SAP products using various authentication methods, such as Microsoft user or their authentication service. This ensures secure access to all systems, both SAP and non-SAP, while giving the company control over user access. Additionally, the solution offers location-based access control. We find that it's already quite flexible and doesn't require much customization. It's mainly about configuration, which doesn't demand technical expertise. Customers often delve deeper into the solution's features to understand how to use it more effectively. They ask questions that are already addressed within the platform. This reliance on the solution's features, alongside their internal on-premises systems, has a very positive impact. The tool is compatible with different products.

Quotes from Members

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

Pros

"The solution is simple to deploy, simple to use, and user-friendly."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The initial setup is very easy."
"Technical support is excellent with Fortinet FortiAuthenticator."
"We have not had issues with Fortinet FortiAuthenticator. It is stable."
"The biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
"Customer service and support are excellent."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The solution has been integrated into our mobile workforce using SAP IAS.

Customers can quickly establish user authentication with SAP IAS in just a few minutes, enabling secure access to specific products or systems based on predefined rules."
 

Cons

"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"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."
"A lot of configurations are available only from CLI."
"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."
"The technical support is mid-range; it's not your wow kind of support, and they're not really there when it comes to support."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"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."
"The technical support team is bad."
"The only improvement I suggest for SAP Single Sign-On concerns employees without emails. We addressed this by allowing users to set up security questions themselves. However, to further enhance this, integrating with mobile SMS for password resets could be beneficial."
 

Pricing and Cost Advice

"It costs more to license the high-availability option."
"The pricing is fair."
"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."
"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."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The tool is free of cost."
