Security Information and Event Management (SIEM) collects, analyzes, and correlates security-related data from across an organization's IT infrastructure in real time. It combines log management and security event monitoring to detect, investigate, and respond to potential threats.
What Does SIEM Do?
SIEM enables organizations to:
- Aggregate logs from servers, applications, networks, and cloud platforms
- Identify anomalies and suspicious activities across systems
- Correlate events to detect complex cyberattacks
- Trigger alerts, automated responses, or incident workflows
- Support compliance reporting with audit-ready dashboards
Providing centralized visibility, SIEM helps security teams quickly detect and respond to incidents before they escalate.
Why Does SIEM Matter?
Modern cyber threats are increasingly sophisticated, targeting networks, cloud systems, and sensitive data. SIEM provides organizations with real-time threat detection and actionable insights, reducing risk from malware, insider threats, and Advanced Persistent Threats (APTs).
SIEM also supports regulatory compliance, including HIPAA, PCI DSS, GDPR, and SOX, by ensuring organizations can demonstrate security monitoring and incident management practices.
