In-house vs. outsourced SOCs: Weighing the pros and cons for modern enterprises

As cyberthreats intensify and digital landscapes evolve, organizations are investing heavily in cybersecurity resilience. With global cyber insurance premiums expected to more than double (from $14 billion in 2023 to $29 billion by 2027), it's clear that security is now a boardroom priority. A well-equipped security operations center (SOC) lies at the heart of cyberdefense, enabling proactive threat detection and rapid incident response.

However, enterprises frequently grapple with whether to outsource security operations to a managed service provider or develop an internal SOC, each of which has unique benefits and drawbacks. Outsourcing options like managed detection and response and managed security service providers (MSSPs) offer scalable alternatives to building in-house capabilities. Having to balance control, costs, expertise, and scalability makes this a critical, complex choice for security leaders.

In this article, we’ll dive into the pros and cons of in-house versus outsourced SOCs, helping enterprises navigate the path to a security model that aligns perfectly with their goals.

Understanding the SOC models

What is an in-house SOC?

An in-house SOC is a dedicated team within an organization that is responsible for continuously monitoring for, detecting, analyzing, and responding to cybersecurity threats. It is built and managed internally, giving enterprises complete control over their security infrastructure, policies, and operations. By enabling closer integration with existing business and IT procedures, this model promotes faster communication and more specialized threat responses. Enterprises can also better understand their data and compliance needs if they have an internal SOC. This configuration is perfect for organizations with complex IT systems or sensitive data that require continuous, expert security monitoring.

What is an outsourced SOC?

An outsourced SOC is a cybersecurity service provided by third-party experts who monitor and manage an organization’s security environment remotely. With this strategy, organizations may benefit from 24/7 monitoring, industry-grade tools, and sophisticated threat detection capabilities without having to pay to build a SOC from scratch. Since it provides access to seasoned professionals and scalable services, it is particularly advantageous for enterprises with financial constraints or little internal experience.

A breakdown of the pros and cons of in-house vs. outsourced SOCs

The following are the benefits and drawbacks of employing an in-house SOC and an outsourced SOC.

In-house SOCs

Outsourced SOCs

Key considerations for CISOs when choosing the right SOC model

A CISO's primary considerations in selecting a suitable SOC model that meets their organization's requirements should be as follows:

1. Costs and budget allocation

CISOs need to evaluate their budget and determine if outsourcing offers a more economical option or if investing in an internal SOC is feasible. In-house SOCs require substantial up-front capital for infrastructure and ongoing costs for staffing, while outsourced SOCs may offer predictable monthly expenses.

2. Expertise and skill sets

CISOs must assess the skill levels required to manage evolving cyberthreats. Outsourced SOCs provide access to a pool of skilled professionals with a wide range of experience from the outset, whereas in-house SOCs can develop specific expertise but need continual training.

3. Scalability and flexibility

An important consideration is how well the chosen SOC model can scale with the organization’s growth or changing security demands. In-house SOCs may find it difficult to scale without extra resources, while outsourced SOCs provide greater flexibility because they can readily adapt to meet fluctuating needs.

4. Control and customization

Full control over security processes and the ability to tailor solutions to the particular requirements of an organization are provided by in-house SOCs, which ensure closer alignment with internal goals. Conversely, outsourced SOCs may limit control and customization, which could have an impact on how well security operations mesh with other business operations.

5. Response times and incident handling

One important consideration is how quickly security events are identified and addressed. While outsourced SOCs frequently provide 24/7 coverage, they may encounter delays because of third-party coordination or time zone differences. In contrast, in-house SOCs enable faster, more direct communication and prompt reactions.

6. Compliance and data privacy

CISOs must ensure the chosen SOC model meets all necessary regulatory compliance requirements, especially if sensitive data is involved. In-house SOCs provide more control over compliance and data privacy, whereas outsourcing can raise concerns about sharing sensitive information with external providers.

7. Integration with existing infrastructure

Another important factor to take into account is the SOC's ability to smoothly integrate with the current IT and security architecture. Outsourced solutions could have trouble integrating with the company's current systems and workflows, while in-house SOCs usually provide superior integration.

Additionally, according to a ManageEngine SIEM survey, 16 out of 27 security analysts stated that greater control and visibility are two of the most important factors affecting an organization's decision between using an in-house SOC and an external SOC provider.

A SOC model decision-making matrix

Leverage this decision-making matrix to decide which SOC model best suits your organizational needs.

How to use this matrix

With a straightforward scale (e.g., 1 means not suitable, and 5 means highly suitable), CISOs can grade each criterion according to the particular requirements of their company, facilitating a strategic, goal-oriented discussion with the board or executive leadership. Each of these criteria can be given points, these points can be added, and then the final decision on what to choose can be made.

For example: The matrix obviously favors an outsourced SOC service if your company highly prioritizes quick deployment, cost-effectiveness, and around-the-clock coverage. An in-house SOC is more suitable if customization, compliance, and data control are your main priorities.

The role of SIEM in enhancing SOC effectiveness

A SIEM solution plays a major role in enhancing SOC efficiency with various capabilities, such as:

• Centralized visibility: Reduces blind spots in monitoring by offering a single-pane view across distributed assets.
• Real-time threat detection: Uses rule-based correlation and UEBA to spot threats early.
• Automated incident response: Reduces the MTTD and MTTR by integrating with SOAR tools to activate predefined playbooks.
• Compliance and auditing support: Delivers out-of-the-box reports for regulations and frameworks like PCI DSS, GDPR, HIPAA, and ISO/IEC 27001.

The following are the top benefits of integrating a SIEM solution into an in-house SOC:

• Complete customization and control: You can fine-tune correlation rules, alert thresholds, and log sources to match internal systems, business processes, and the threat landscape.
• Deep integrations with internal tools: A SIEM solution improves visibility and response times by integrating seamlessly with existing infrastructures, such as firewalls and IAM, DLP, EDR, and ticketing systems.
• Data sovereignty and privacy assurance: Sensitive security logs remain within the organization, ensuring better compliance with internal data governance and regulatory mandates.
• Quicker contextual analysis: Internal teams can investigate incidents more quickly and accurately since they have a greater understanding of the IT environment and business operations.
• Strategic security maturity development: This integration fosters long-term in-house expertise and a security-first culture that is in line with business objectives and risk management priorities.

The following are the top benefits of integrating a SIEM solution with an outsourced SOC:

• Expert-driven monitoring and rule tuning: You can leverage skilled threat hunters and security experts who continuously refine correlation rules and detection logic to tackle emerging threats.
• Rapid deployment: Preconfigured SIEM platforms with ready-made dashboards, alerting rules, and compliance templates accelerate implementation and the ROI.
• Lower operational overhead: This eliminates the need for internal staffing, maintenance, and infrastructure management, reducing both the costs and administrative burden.
• Scalable, flexible service models: The SIEM solution seamlessly scales with organizational growth, enabling your business to expand monitoring or integrate new log sources without rebuilding the infrastructure.
