Security Information and Event Management (SIEM)
A platform that aggregates and analyzes security log data from across an organization to detect and alert on threats.
A Security Information and Event Management (SIEM) platform collects log and event data from across an organization's servers, network devices, applications, and endpoints, then correlates and analyzes it in real time to detect suspicious patterns and generate alerts. It acts as a central nervous system for an organization's security monitoring.
Without a SIEM, security teams would have to manually check logs scattered across dozens of separate systems, an impossible task at scale. By correlating events, like a failed login on one system followed by a successful one on another, a SIEM can surface an attack that no single log entry would reveal on its own.
