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.
