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

If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
 

Setup Cost

Fortinet FortiSIEM provides flexible pricing that can be cost-effective, but costs may increase with additional modules and scalability.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.

Reliability and scalability have helped me in my work, especially because the license for Fortinet FortiSIEM is excellent from a cost perspective, and we can add more collectors as we expand.
Cybersecurity Team Leader at EMAK For Integrated Solutions
The weakest point is it doesn't cover almost all the devices, so the customer has to be more dependent on the parsers to be written by the Professional Services team.

Network Engineer at Ogma Consulting
Comprehensive monitoring boosts security, yet incident management features need expansion
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. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.
MD
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
Offers comprehensive report generation while maintaining ease of integration
We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that. We can add some new features regarding AI in the future for Trellix ESM, but the maturity will take a longer time. There are many false positives that happen in an environment during the first couple of months, or around six months, so the system analyst is not able to identify whether the event which has occurred is a true positive or a false positive.
