SIEM, or Security Information and Event Management, is a cybersecurity solution that gathers, monitors, and analyzes security data from various sources across an organization’s IT environment. By collecting logs and alerts from devices, applications, and networks, SIEM systems help security teams detect unusual activity, investigate incidents, and respond quickly to potential threats. SIEM platforms often use real-time monitoring, correlation rules, and advanced analytics to identify suspicious patterns or breaches, making them essential for maintaining strong security and meeting compliance requirements.
