FortiSIEM is designed to be the backbone of your security operations team, delivering capabilities ranging from automatically building your inventory of assets to applying cutting edge behavioral analytics to rapidly detect and respond to threats. FortiSIEM is the industry’s only security operations platform with a fully inbuilt configuration management database (CMDB).


Unified NOC/SOC/OT Visibility and Analytics

With its CMDB, FortiSIEM can automatically leverage active and passive methods of discovery to build your asset inventory. This includes devices and their applications, and it tracks the state of those assets over time. Continuously collecting context such as configurations, performance, vulnerability, their relationship to business services, and their Purdue model OT associations so teams know the state of the environment when an incident arises. And they have the visibility needed to fix problems proactively.

Next-Generation SOC Automation

FortiGuard Labs threat intelligence experts work 24x7 to analyze the latest threats and build mitigations extremely fast. Combined with the latest AI-driven behavior anomaly detection capabilities such as UEBA, FortiSIEM protects against both known and unknown threats. Statistical models are leveraged to pick up deviations both strange and impossible, such as logins across geographical regions that would require superhero speeds (or stolen credentials).


New: Visual Threat Hunting Through Link Analysis

FortiSIEM brings together visibility, correlation, automated response, and remediation in a single, scalable solution. It reduces the complexity of managing network and security operations to effectively free resources, improve breach detection, and even prevent breaches. To power more effective threat hunting, FortiSIEM now includes new link graph technology which allows for easy visualization of relationships between users, devices, and incidents.
