Security Orchestration, Automation, and Response (SOAR) platforms reduce manual security-analyst workload and standardize incident-response workflows across heterogeneous tool ecosystems. Core capabilities include alert triage and case management, automated playbooks for enrichment, investigation coordination, and containment actions; integrations across SIEM, EDR, email security, IAM, ticketing, and cloud platforms; low-code/no-code playbook authoring; and response-metric reporting (MTTR, automation ratio, analyst time saved). Modern SOAR platforms increasingly merge with SIEM and XDR capabilities as vendors consolidate the detection-and-response stack. Leading vendors include Palo Alto Cortex XSOAR, Splunk SOAR (Phantom), Torq, Tines, Swimlane, ServiceNow Security Operations, and Google Chronicle SOAR.
