What is SIEM?
Security Information and Event Management (SIEM) is a solution that collects, analyzes and correlates security events from your entire infrastructure to detect threats in real-time.
The Brain of Your Security
Imagine having thousands of devices (servers, firewalls, applications, workstations) generating millions of events per day. How do you identify an attack in the middle of all this noise?
That's exactly what SIEM does: centralize all these logs, analyze them intelligently using correlation rules and artificial intelligence, then alert only on critical events.
Microsoft Sentinel takes this concept even further by natively integrating SOAR (response automation) and using Microsoft AI for advanced detection.
