Security Information and Event Management, or SIEM, refers to a comprehensive approach to security management that combines Security Information Management (SIM) and Security Event Management (SEM) into one solution. SIEM systems provide a centralized platform for collecting, analyzing, and managing security data from various sources across an organization’s IT infrastructure.

SIEM plays a crucial role in enhancing the security posture of organizations by providing visibility into their IT environments, detecting and responding to security threats, and facilitating compliance with regulatory standards.
