Security Automation with Elastic Workflows: From Alert to Response
Elastic has introduced Elastic Workflows, a native automation capability within its SIEM that allows security teams to build YAML-based playbooks for alert triage, enrichment, and response. The feature integrates directly with Elasticsearch data, external threat intelligence platforms, and AI-driven analysis tools to streamline security operations.
Key Takeaways
- Elastic Workflows enables native automation within the Elastic SIEM without requiring external SOAR tools.
- Workflows are defined in YAML and consist of triggers, steps, and data flow mechanisms.
- Built-in connectors allow seamless integration with external services like VirusTotal and Slack.
- AI steps (ai.classify, ai.summarize, ai.agent) can be integrated to handle complex, non-deterministic triage logic.
- Workflows can be invoked by Elastic's Agent Builder to execute tasks during automated investigations.

Detection Engineering Assessment
EDR Visibility: N/A — The article discusses a SIEM automation feature, not endpoint detection of a specific threat. Network Visibility: N/A — The article discusses a SIEM automation feature, not network detection of a specific threat. Detection Difficulty: N/A — Not applicable as this is a guide on building automation workflows, not detecting a specific adversary.
Required Log Sources
- Elasticsearch alerts-security* indices
Hunting Hypotheses
| Hypothesis | Telemetry | ATT&CK Stage | FP Risk |
|---|---|---|---|
| Identify hosts generating multiple distinct security alerts within a 24-hour period to prioritize automated triage and case creation. | SIEM alerts | Execution | Medium |
Recommendations
Immediate Mitigation
- N/A
Infrastructure Hardening
- Implement native SIEM automation to reduce manual alert triage and response times.
User Protection
- N/A
Security Awareness
- Train SOC analysts on writing and maintaining YAML-based automation workflows and ES|QL queries.
