Understanding the SOC
A Security Operations Center (SOC) is the organizational function responsible for continuous security monitoring and incident response. The SOC team monitors alerts from SIEM, EDR, and other security tools, investigates suspicious activity, and takes action to contain and remediate threats. The SOC operates as the front line of an organization's cyber defense.
Building an in-house 24/7 SOC requires significant investment in personnel (typically 8-12 analysts for continuous coverage), technology (SIEM, SOAR, EDR, threat intelligence), and facilities. This cost puts in-house SOCs out of reach for most small and mid-market organizations, driving the growth of outsourced SOC-as-a-Service and Managed Detection and Response (MDR) providers.
Regardless of whether the SOC is internal or outsourced, the CISO or vCISO is responsible for defining the SOC's mission, capabilities, escalation procedures, and performance metrics. The SOC is a key component of the security program that requires ongoing oversight and optimization.
Core Functions
SOC Models
In-house SOC
Fully internal team and infrastructure. Maximum control but highest cost. Best for large enterprises.
Outsourced SOC / MDR
Third-party provider handles monitoring and initial response. Cost-effective for SMBs and mid-market.
Hybrid SOC
Internal team handles escalated incidents while an outsourced provider manages 24/7 monitoring.
Virtual SOC
No dedicated facility. Analysts work remotely using cloud-based tools. Common in distributed organizations.
