Security Operations Center Basics: Building vs Outsourcing

A Security Operations Center (SOC) is the central function responsible for monitoring, detecting, analyzing, and responding to cybersecurity threats in real-time. Whether staffed by in-house analysts or outsourced to a managed provider, the SOC provides continuous visibility into your security posture and serves as the first responder when incidents occur.

Our Approach: This comparison uses side-by-side evaluation using identical conditions. Factors in our assessment included update frequency, privacy policy, detection accuracy. Brands featured did not pay for or influence their inclusion.

What a SOC Does

Continuous monitoring. The SOC monitors security alerts from endpoints, network devices, cloud services, email gateways, and applications 24/7/365. Attackers do not operate on business hours, and the majority of ransomware deployments occur on weekends or holidays when response teams are unavailable.

Alert triage and investigation. Not every alert is an incident. SOC analysts filter false positives, prioritize genuine threats, and investigate suspicious activity. A mature SOC processes thousands of alerts daily, escalating the small percentage that represent real threats.

Incident response. When a genuine incident is confirmed, the SOC initiates the response process: containment, eradication, recovery, and documentation.

Threat hunting. Proactive analysts search for threats that evade automated detection by analyzing behavioral patterns, hunting for indicators of compromise, and testing hypotheses about attacker techniques.

Build vs. Buy

In-house SOC provides maximum control, customization, and institutional knowledge but requires significant investment. A minimum viable 24/7 SOC needs 5-7 analysts across shifts, a SIEM platform, EDR tools, threat intelligence feeds, and a physical or virtual facility. Annual costs start at $1 million for staffing alone, before technology costs. Finding and retaining skilled SOC analysts is a persistent challenge due to the global cybersecurity talent shortage.

Managed SOC (MSSP/MDR) outsources monitoring and response to a specialized provider. Managed Detection and Response (MDR) providers like Arctic Wolf, Expel, and Red Canary offer 24/7 monitoring with experienced analysts at a fraction of in-house costs (typically $100,000-$500,000 annually depending on scope). You gain immediate capability without building a team, but lose some control over procedures and response decisions.

Hybrid model. Many organizations use a hybrid approach: an MSSP handles after-hours monitoring and initial triage, while an in-house security team handles investigations, incident response, and strategic security decisions during business hours.

Key Technologies

SIEM aggregates and correlates logs from across the environment. See our SIEM solutions guide for platform comparisons.

SOAR (Security Orchestration, Automation, and Response) automates repetitive tasks like alert enrichment, phishing email analysis, and initial containment actions, freeing analysts for higher-value work.

EDR/XDR provides endpoint visibility and automated response capabilities.

SOC Maturity Levels

Level 1: Reactive. The SOC monitors alerts from existing tools and responds to confirmed incidents. Coverage may be limited to business hours. This is the minimum viable SOC.

Level 2: Proactive. The SOC includes threat hunting, custom detection rule development, and integration with threat intelligence feeds. Coverage extends to 24/7 through staffing or an MSSP partnership.

Level 3: Optimized. The SOC uses advanced analytics, SOAR automation, and comprehensive detection engineering mapped to the MITRE ATT&CK framework. Continuous improvement through purple team exercises and metrics-driven optimization.

Most organizations start at Level 1 and progress over time. The transition from Level 1 to Level 2 typically takes 12-18 months and represents the most significant improvement in detection capability. Level 3 requires sustained investment in people, processes, and technology over several years.

SOC Analyst Burnout and Retention

SOC analyst burnout is a significant operational challenge. Alert fatigue, repetitive tasks, night shifts, and the pressure of constant threat exposure contribute to high turnover rates. Address burnout through automation of repetitive tasks (SOAR), career development paths from Tier 1 to Tier 3 and into engineering or management, reasonable shift schedules, and a culture that values analyst well-being. Retaining experienced analysts preserves institutional knowledge that is difficult and expensive to replace.
