What is SOAR?
Security Orchestration, Automation and Response (SOAR) is a category of security platform that connects disparate security tools, automates repetitive analyst tasks, and orchestrates coordinated responses to security incidents — all through pre-built workflows called playbooks.
The three pillars of SOAR reflect its name: Orchestration connects tools via APIs — when a SIEM fires an alert, SOAR can automatically query threat intelligence, look up the asset owner in CMDB, and check EDR telemetry, all within seconds. Automation executes response actions without analyst intervention — blocking an IP at the firewall, quarantining an endpoint, revoking a compromised credential. Response coordinates the human side — creating tickets, notifying the right team, and tracking case progress through resolution.
SOAR emerged as a direct response to the alert volume problem. Modern enterprise SIEMs generate thousands of alerts per day. Human analysts cannot triage all of them — alert fatigue leads to missed detections and analyst burnout. SOAR's role is to handle the automatable portion so analysts can focus on the cases that genuinely require human investigation and judgment.
SOAR vs SIEM — what's the difference?
SIEM and SOAR are complementary tools that serve different functions in a security operations workflow:
- SIEM (detective function): Collects logs, correlates events, detects anomalies, and generates alerts. The SIEM tells you something suspicious may have happened. Splunk, Microsoft Sentinel, IBM QRadar.
- SOAR (response function): Receives alerts from the SIEM (or other sources), enriches them automatically, executes playbook logic, and either resolves the incident automatically or creates a structured case for analyst investigation. Splunk SOAR, Palo Alto XSOAR, IBM QRadar SOAR.
The workflow is: SIEM detects → alert fires → SOAR picks up the alert → playbook runs → either auto-closes (false positive confirmed, low-risk confirmed) or creates enriched ticket for analyst. In practice, modern platforms like Microsoft Sentinel and Splunk increasingly combine SIEM and SOAR capabilities in a single product.
How SOAR playbooks work
A SOAR playbook is a flowchart of automated actions that execute in response to a specific trigger. A well-designed phishing triage playbook might look like this:
- 1Trigger
User reports a suspicious email via the "Report Phishing" button. SOAR ingests the report and starts the playbook.
- 2Enrichment
Automatically extract URLs and attachments. Query VirusTotal for reputation scores. Check sender domain against threat intel feeds. Look up whether any other users received the same email.
- 3Decision Point
If all indicators are clean → auto-close as false positive, notify user. If indicators are suspicious → escalate to analyst with enrichment data pre-populated.
- 4Automated Response (if confirmed malicious)
Quarantine the email from all inboxes. Block sender domain at email gateway. Block malicious URLs at web proxy. Create incident ticket. Notify IT security team.
- 5Documentation
Auto-generate timeline, log all actions taken, record analyst decisions, close ticket with outcome. Full audit trail maintained.
SOAR removes the work that doesn't require analysts. A well-implemented SOAR platform handles phishing triage, IP reputation lookups, and routine ticket creation automatically — freeing your team for real investigations. The analysts who master SOAR tools become significantly more productive and are in high demand in the jobs market.
Key benefits for SOC teams
- Dramatically reduced MTTR: Automated playbooks can reduce mean time to respond from hours to minutes for common incident types.
- Consistent process execution: Playbooks run the same way every time — no human fatigue, no steps skipped, no variation between shift changes.
- Analyst burnout reduction: By handling tier-1 alert triage automatically, SOAR removes the most repetitive and demoralising work from analyst queues.
- Scalability: SOAR multiplies analyst capacity — a team of five can handle alert volumes that would previously require 20 analysts.
- Compliance audit trail: Every automated action is logged — who did what, when, and why — simplifying regulatory reporting and post-incident reviews.
Leading SOAR platforms
- Splunk SOAR (formerly Phantom): The market leader, with hundreds of pre-built app integrations. Deep Splunk SIEM integration. Enterprise-grade.
- Palo Alto XSOAR (formerly Demisto): Strong multi-vendor integration, flexible Python-based playbook engine, widely used in MSSPs.
- Microsoft Sentinel: Built-in SOAR capabilities (Logic Apps automation) tightly integrated with the Microsoft security ecosystem — natural choice for Microsoft-centric organisations.
- IBM QRadar SOAR: Mature platform with strong compliance workflow capabilities, popular in regulated industries like banking and healthcare.
- Google Chronicle SOAR: Cloud-native, strong threat intelligence integration, growing market share in cloud-first organisations.
SOAR in a SOC analyst career
SOAR skills are increasingly expected at L2 and L3 SOC analyst levels, and are differentiating at L1. Analysts who understand how to build and modify playbooks — particularly those with Python skills — command higher salaries and have more career options.
Key skills to develop: understanding of SOAR concepts (orchestration, playbook logic, API integrations), hands-on experience with at least one major platform (Splunk SOAR has a community edition; Microsoft Sentinel Automation is available in Azure free tier), and Python for custom integrations. These skills translate well into DevSecOps and security engineering roles beyond the SOC.
