Cyber incidents are expensive. IBM reports that the average data breach costs organisations $4.45 million globally, not including reputational or regulatory damage. A Security Operations Center (SOC) acts as a frontline defence, monitoring networks, detecting threats, investigating suspicious activity, and coordinating incident response. The primary goal of a SOC is to ensure that security events are handled quickly and consistently, minimising impact and operational disruption.

Deciding whether to build an internal SOC or rely on a managed service is therefore a critical strategic and financial consideration. The choice affects not only operational cost, but also response speed, resilience, and the organisation’s ability to keep pace with evolving cyber threats.

Understanding how these two models differ in structure, scalability, and total cost of ownership is essential for making a defensible, future-ready decision.

A SOC combines people, processes, and technology to protect the organisation from cyber threats.

Internal SOC: Built entirely in-house, using company-owned infrastructure and permanent staff.

Managed SOC: Outsources the same functions to an external provider, delivering continuous monitoring, alert triage, investigation, and incident response.

Costs differ sharply between the two models:

Internal SOCs require capital expenditure for tools, hardware, and facilities, plus ongoing operational costs such as salaries, training, and infrastructure maintenance.

Managed SOCs are typically subscription-based, allowing organisations to pay for service coverage rather than assets, creating predictable operating expenses.

Running a full internal SOC is a significant investment. Coverage expectations alone create major cost challenges. For example, a basic SOC providing detection with limited investigation typically costs $1.5 million per year, including:

• $1.2M for 12 staff (wages and benefits)
• $300K for technology, including SIEM, SOAR, and log storage
• Setup timeline: ~3 months to launch, 6–9 months to reach steady-state operations

Additional factors contributing to cost include:

• Multiple analyst tiers (triage, investigation, response)
• SOC managers and escalation engineers
• Ongoing training, certification, and shift coverage
• Infrastructure licensing, tuning, and maintenance

Staffing pressures are also significant: Tier 1 SOC analyst salaries average $102,315, and 45% of organisations expect salaries to increase by ~29% due to talent shortages.

Recruiting skilled analysts is challenging, with 84% of organisations reporting difficulty filling cybersecurity roles.

Operating an internal SOC effectively often requires extending the business to include a specialised cybersecurity arm, with costs for facilities, equipment, and operational support. For many enterprises, in-house SOCs serve as a strategic capability rather than a purely tactical function.

A managed SOC packages core detection and response functions into a continuous service, which can include:

• Real-time monitoring and alert triage
• Incident escalation and coordination
• Threat intelligence enrichment
• Threat hunting, vulnerability prioritisation, and compliance reporting (depending on service tier)

Pricing is generally based on the level of service required, not the volume of logs or assets. Organisations select the tier that aligns with their risk profile and operational needs, whether that is basic monitoring, advanced investigation, or full 24/7 coverage.

By design, managed SOCs emphasise predictability. Organisations know what they are paying each month while gaining access to specialised expertise that is difficult and expensive to recruit and retain internally.

In practical terms, internal SOCs concentrate cost, skills dependency, and operational risk, whereas managed models distribute these across a broader delivery framework, making budgeting and staffing more predictable.

Managed SOCs are designed for speed, scale, and consistency. Providers operate mature playbooks, automation pipelines, and dedicated response teams that reduce manual workload.

Managed SOCs deliver speed, scale, and consistency:

• Continuous coverage without internal shift management
• Access to specialised detection and response expertise
• Transparent, predictable pricing
• Built-in reporting aligned to regulatory needs
• Alignment with security operations’ best practices

Internal SOCs remain viable in certain scenarios:

• Large enterprises with established infrastructure and specific security workflows
• LHighly regulated industries requiring tight data controls or jurisdiction-specific handling
• LOrganisations with significant prior investment in detection platforms

For these organisations, in-house SOCs function as a strategic capability, not just a cost centre

Not all providers operate at the same maturity level. Evaluate:

• Incident response ownership and escalation paths
• Reporting transparency and analyst notes
• SIEM and SOAR integration flexibility
• Regulatory mapping and audit readiness
• Contractual service level commitments

Strong managed SOC providers should demonstrate adaptability rather than forcing a fixed operating model. This is especially important when aligning services with existing business processes and compliance needs.

Internal SOCs emphasise control, ownership, and institutional expertise. Managed SOCs prioritise agility, predictable spend, and faster operational maturity.

Deciding which approach suits your organisation depends on scale, regulatory context, and internal skill depth. The benefits of SOC as a service increasingly focus on resilience, speed, and governance rather than cost alone. Leaders should evaluate both models using total exposure reduction as the primary metric.

Every environment has unique operational pressures, regulatory constraints, and risk tolerances. NCINGA helps organisations design security operations that align with these realities, whether through advisory, transformation, or managed delivery models.
