Security Information and Event Management (SIEM) tools play a crucial role in modern cybersecurity by collecting data from various systems to identify patterns and generate actionable intelligence. While traditional SIEM solutions faced challenges such as expensive on-premise deployment, limited integrations, and a focus on external threats, modern cloud-based SIEMs address these issues through scalable data handling, compliance with regulations, and enhanced threat detection by considering both internal and external threats. These advancements include leveraging User and Entity Behavior Analytics (UEBA) for detecting anomalies and integrating with enterprise programs to provide meaningful alerts and recommendations for action. Modern SIEMs are more accessible to non-security experts, offering relevant alerts and automated responses, thus enabling businesses to predict security threats, conduct in-depth data analysis, and enhance incident response capabilities.
