Security Information and Event Management (SIEM) collects and correlates logs from endpoints, identities, apps, cloud, and network tools to surface real incidents fast. If you’re asking what is Security Information and Event Management, it’s the system of record for security telemetry—turning raw events into alerts, timelines, and reports your team can act on.
We often see SIEM used to reduce dwell time and meet audit requirements by unifying data in one searchable place. Modern platforms enrich events with threat intel, map activity to frameworks (like MITRE ATT&CK), and integrate with automation for faster response.
Key capabilities include:
- Log collection & normalization: One schema, many sources.
- Correlation & analytics: Detect patterns across tools and users.
- Incident investigation: Timelines, queries, and evidence retention.
- Compliance reporting: Prebuilt dashboards and auditable trails.
- SOAR integration: Automate triage and response playbooks.
Our take? SIEM is your visibility backbone—most effective when tuned for fidelity and paired with response workflows.
