Room For Improvement

Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
SentinelOne Singularity AI SIEM struggles with stability, integrations, UI issues, high pricing, and requires improved support and automation.
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.
MM
Information Security Principal at a venture capital & private equity firm with 1,001-5,000 employees
Consolidated security operations have improved detection speed and reduced SOC costs
There is room for improvement when it comes to the technical support quality and expertise of SentinelOne. Sometimes, the technical support team does not know how to resolve certain issues and takes time to respond, often requiring follow-up interactions within 24 hours. SentinelOne Singularity AI SIEM can be improved in terms of support capabilities. Some logs from the server side need to be ingested. Secureworks was integrating with domain controllers and other systems, but SentinelOne still has some gaps. Some vendors cannot be integrated directly. For example, we are using Cisco Umbrella for DNS security, and we have to integrate it through an Amazon S3 bucket where we dump the logs and SentinelOne reads them from that location. For some Microsoft integrations, we must enable certain storage components and pay Microsoft directly to retrieve logs. There is no direct integration, so we must access the logs through that workaround. Previously with Secureworks, we had direct integration with Microsoft. Direct integration with Microsoft is not available now. SentinelOne needs to work on many product integrations to enable direct connectivity.
