Fortinet Reviews, Ratings & Features 2026 | Gartner Peer Insights

Security information and event management (SIEM) is a configurable system of record that collects, aggregates and analyzes security event data from on-premises and cloud environments. SIEM processes security event data for the purposes of threat detection, investigation and response. It natively supports data normalization and offers user-configurable detection content and reporting to orchestrate threat mitigation and satisfy compliance requirements. These solutions are delivered via a SaaS platform or client-hosted on-premises or private cloud. The security information and event management (SIEM) system must assist with: 1. Aggregating and normalizing data from various IT and operational technology (OT) environments. 2. Designing and executing near real-time monitoring and alerting content. 3. Enriching and investigating security events of interest. 4. Supporting manual and automated response actions. 5. Maintaining and reporting on current and historical event data.

FortiSIEM

Fortinet

System Engineer

Overall, over the past 1.5 years of using the FortiSIEM daily in our environment the overall experience has been positive, particularly in terms of visibility, correlation and threat detection across our infrastructure. FortiSIEM helped us centralize log collection and provide real-time insights into security events, which improved our monitoring and incident response processes. The correlation engine and automation feature  reduced alert noise and helped prioritize actionable incidents, enabling a more efficient SOC operation.

Integration with our existing Fortinet ecosystem including firewalls, endpoints, agents and network devices worked smoothly. The consolidated dashboard made it easier to track trends, investigate anomalies and manage incidents without switching between multiple tools. Scalability - has been reliable as log sources and volume have increased over time.

That said, FortiSIEM is not a set-and-forget solution. Initial deployment, tuning of parsers, and alert optimization required effort and expertise. Once stabilized, however, the platform delivers consistent value and meaningful security insights.
