SIEM platforms provide a centralized view of an organization's security posture by ingesting log data from sources like firewalls, intrusion detection systems, servers, and endpoints, and applying advanced analytics to detect patterns indicative of a security event or breach. By automating real-time monitoring, alerting, and reporting on security events, SIEM helps organizations maintain compliance with regulatory standards, identify vulnerabilities, and streamline incident response processes.
