Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

More Fortinet FortiSIEM pros

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

Cons

"Its training can be improved. Its price also needs to be improved."

"Their product support, in general, is not that great. The product support is in the same ecosystem. Their support is improving but it's not that great.vvv"

"When our team tried configuring logs for Microsoft SQL, it did not work."

"When an alert triggers in Fortinet FortiSIEM, the layout or format can feel limited"

"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."

"The process of installing Fortinet FortiSIEM and the customization of the alerts take too long."

"The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."

"The solution needs to do a better job with third party integration. Right now, that's lacking on the solution. I specifically am talking about the AWS environment. Most of the AWS environment products do not have that capability to integrate."

More Fortinet FortiSIEM cons

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

Pricing and Cost Advice

"Its price can be better. We are Fortinet partners, so we can get discounts, but its price can be an issue at the beginning for others. There is a licensing scheme for every case. There are three licensing schemes that we can choose from."

"Fortinet's products are not expensive, it is less than the competition."

"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."

"If one is cheap and ten is expensive. I rate the tool's price as an eight out of ten. Compared with Splunk or Oracle, Fortinet is cheap."

"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."

"We pay for a license for FortiSIEM. We pay for the license and renewal."

More Fortinet FortiSIEM pricing and cost advice

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."
