## What Is SIEM? | Security Information & Event Mgmt
What Is SIEM? SIEM (Security Information and Event Management) a security solution that collects and analyzes security data from across an organization's IT infrastructure. SIEM helps detect threats, investigate incidents, and meet compliance requirements.

## Why This Matters for Your Business
SIEM aggregates logs from firewalls, servers, endpoints, and cloud services into a single pane of glass — making it possible to detect coordinated attacks that would be invisible when looking at individual systems. For businesses with compliance obligations, SIEM is often a mandatory control.
