Room For Improvement

Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.

Recently, they revised it to a subscription-based, all-inclusive license.
IT Solutions Product Manager at a computer software company with 11-50 employees
The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products.
Network Engineer at Laminar Communications Pty Ltd
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management.
Network Engineer at Ogma Consulting
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.
Associate Vice President at Novac Technology Solutions
The interface flickers frequently, and sometimes it does not load properly.
IT Security Analyst at a tech consulting company with 11-50 employees
Whenever OT security comes into the picture, the customers do not allow us to integrate their OT devices on a cloud. It should be available on-premises because the OT SIEM market, in the India market for instance, is something around a four to eight billion dollar market.

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.
reviewer2915043 - PeerSpot reviewer
System Engineer at a consultancy with 11-50 employees
Centralized monitoring has improved threat detection speed and simplified alert investigations
It would be helpful if some alerts had cleaner, clearer explanations right away, such as suggesting next steps inside the alert, and fewer clicks to get from alert to raw event details would make the triage even faster. Integration could be more plug-and-play, and improving built-in guidance for new analysts would help cut the learning curve. Performance-wise, it is adequate for us, but easier bulk searches would make investigations smoother. It would be helpful for each alert to come with clear suggested next steps right inside the alert, so analysts do not have to guess or click around too much. Making integration more plug-and-play would smooth out setup for new data sources.
