What Is a SOC? Security Operations Center Explained
What is a SOC (Security Operations Center)? Learn what a SOC does, how it's structured, the tools it uses, and modern alternatives for lean teams.
SOC definition
A Security Operations Center (SOC) is the centralized function responsible for monitoring, detecting, investigating, and responding to cybersecurity threats. It can be a physical facility, a virtual team, or an AI-powered platform.
What a SOC does
Continuous monitoring of security tools and logs. Threat detection using rules, analytics, and AI. Alert triage and investigation. Incident response and containment. Threat hunting. Compliance reporting.
SOC team structure
Traditional SOC: Tier 1 (triage), Tier 2 (investigation), Tier 3 (threat hunting), SOC Manager. Modern lean SOC: 1–3 analysts + agentic AI automation handling Tier 1–2 work.
SOC tools and technology
SIEM for log management. EDR/XDR for endpoint detection. SOAR for response automation. Threat intelligence feeds. Case management and ticketing. Or: an agentic SOC platform that combines all of these.
SOC models: build, buy, or automate
In-house SOC ($1M+ annually). Managed SOC/MDR ($10–50+ per user/month). Agentic SOC platform (predictable pricing, autonomous operations). Most SMB/mid-market teams benefit from the agentic model.
