Security orchestration, automation and response (SOAR) is a class of tools that connect security products and run automated playbooks to triage alerts and respond to incidents faster.
How SOAR works
A security operations center receives thousands of alerts a day from firewalls, EDR, email gateways and a SIEM. A SOAR platform sits on top of these tools and combines three capabilities:
- Orchestration – integrations (connectors) with hundreds of products through their APIs, so one workflow can query an EDR, a mail server and an identity provider.
- Automation – playbooks that perform routine steps without an analyst: enriching an alert with threat intelligence, checking file hashes, detonating attachments in a sandbox.
- Response and case management – isolating a host, disabling an account, blocking a domain, and documenting every action in a ticket.
Well-known products include Splunk SOAR (formerly Phantom), Palo Alto Networks Cortex XSOAR (formerly Demisto) and the automation features of Microsoft Sentinel. Many SIEM and XDR platforms now include SOAR functions.
Why SOAR matters
Alert fatigue and staff shortages are core SOC problems. Automating repetitive steps cuts response time from hours to minutes, for example when a phishing report is analysed and the same message is removed from every mailbox automatically. Playbooks also make incident response consistent and auditable.
Best practices
- Start with high-volume, well-understood use cases such as phishing triage.
- Keep a human approval step for disruptive actions like shutting down servers.
- Protect SOAR credentials carefully – the platform holds privileged access to many systems.
- Review and test playbooks regularly as tools and threats change.
