Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR.

FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware.

The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products.

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

There could be improvements like introducing some solutions directly into FortiSIEM to avoid the need for separately purchasing additional tools like FortiStore.

Sometimes, if there are changes made by a user on a database server, it can be difficult to get that information on the fly. I would like to see a situation where once I specify a user with the database server I need, and with the changes they have performed on that, I don't need to continue my search pattern to drill down just to get the information.

The tool's technical team's response time is too high, and they are not available even when they know that there are many pending issues.

Improvements include making it easier for users to create their normalizers. Fortinet FortiSIEM uses XML for normalizing and parsing, which can be tedious and time-consuming. A simpler way of using regex could be helpful.
