In-house SOC team or outsourcing? What cyber security strategy should you choose for your company?

Every growing organization at some point in its digital evolution faces a fundamental question: how do you ensure that you have an advanced, 24/7 capability to detect and respond to cyber threats? Simple security measures such as antivirus and firewalls are no longer sufficient. It is becoming a necessity to have a Security Operations Center (SOC). This is the strategic moment when a company must make one of the most important investment decisions, known in the industry as the “build or buy” (build vs. buy) dilemma.

On the one hand, the vision of building an in-house SOC team entices with the promise of full control, dedicated company knowledge and maximum customization. On the other hand, the reality of this undertaking is a huge, multi-year financial and operational commitment. The alternative is to “buy” this capability as a service, i.e. outsourcing to a specialized MDR (Managed Detection and Response) provider. This is a path that offers immediate access to experts and technology. Choosing between these two paths is not easy and requires a cool, business calculation. This article will take you through a detailed analysis of both models, comparing their real costs, efficiencies, risks and strategic benefits.

Why is the “build or buy” (build vs buy) decision in cyber security so crucial?

The decision whether to build an in-house SOC or use an external partner is much more complex than a simple technology choice. It is a strategic decision that will have long-term financial, operational and cultural implications for the entire organization. The wrong choice can lead to wasting millions of zlotys on an inefficient operation or, conversely, to losing control of a key area of the company.

The “build” approach means making a commitment to create and maintain an entirely new, highly specialized business unit inside the company. It requires not only a huge initial investment, but also a willingness to continuously invest in people, training and technology to keep up with the rapidly changing threat landscape. This is the path for the largest, most mature and determined organizations.

The “buy” approach is the decision to treat advanced security monitoring as a service, much like accounting or legal services. It means focusing your own resources on your core business (core business) and entrusting a critical but highly specialized function to an outside expert. It’s a path that allows you to quickly achieve a high level of cyber resilience with much lower risk and more predictable costs.

What are the perceived advantages of having your own internal SOC team?

The decision to build an in-house SOC team is often motivated by several strong, though not always fully justified, arguments. The most important of these is full control. Having your own team gives you a sense of complete authority over security operations, tools and data. All processes are performed in-house, and sensitive data does not leave the company’s infrastructure, which in some specific industries can be a key requirement.

The second advantage often cited is deep knowledge of the business context. Internal analysts, being part of an organization, over time gain a unique understanding of its applications, business processes and “normal” user behavior. In theory, this allows them to distinguish more quickly and accurately between real threats and anomalies arising from the specifics of the company’s operations.

The third argument is the possibility of maximum customization. An in-house SOC can be 100% “tailored” to an organization’s needs. The team can build custom detection rules, create unique playbooks and integrate with niche internal systems, which can be more difficult with standard services offered by external providers. Keep in mind, however, that each of these advantages comes at a steep price.

What hidden costs make up the real Total Cost of Ownership (TCO) of an internal SOC?

When analyzing the cost of building an in-house SOC, companies often focus only on the obvious expenses, such as software licenses. This is a big mistake. The Total Cost of Ownership (TCO) is much higher and includes a number of hidden but extremely important items.

1. personnel costs (about 60-70% of TCO): This is the largest and most underestimated cost. Providing viable 24/7 coverage requires a full-time staff of at least 8-10 people (L1/L2/L3 analysts, engineers, manager). Consider not only their high salaries, but also the cost of recruiting (often by specialized agencies), training, certification, benefits and taxes.

2. technology costs (about 20-30% of TCO): These include annual licensing costs for key software: the SIEM platform, EDR/XDR systems, SOAR platform, vulnerability scanners, Threat Intelligence data subscriptions. Added to this are the costs of the hardware and infrastructure (servers, storage) on which these systems will run.

3. operations and maintenance costs (about 10% of TCO): These are all other costs, such as maintaining the physical space for the SOC, electricity costs, technical support from software vendors, and the cost of continuous development and improvement of tools and processes.

A fair TCO calculation often shows that the cost of building and maintaining even a small, in-house SOC for 3 years can many times exceed the cost of subscribing to an MDR service at the same maturity level.

When is building your own SOC justified, and when is MDR the obvious choice?

The decision to choose an operating model should be based on an honest assessment of the organization’s maturity, scale, resources and risk profile.

Building an in-house SOC may be justified for very large, global corporations or government organizations that meet several key conditions. They must have a budget in the tens of millions per year, the ability to attract and retain the best talent from the market, and unique, highly specific security or compliance requirements that no third-party vendor can meet. For such organizations, security is often a key component of their product or service.

Outsourcing under the MDR model, on the other hand, is the obvious and strategically sound choice for the vast majority of medium and large companies. It’s ideal for companies that need advanced 24/7 protection, but don’t have (and don’t want to have) the expertise to become a cyber security company. MDR is also the best choice for organizations that need to quickly raise their level of maturity, for example, in response to new regulatory requirements (like the NIS2 directive) or increasing pressure from management after a high-profile incident in the industry.

What key questions should you ask yourself before making a final decision?

Before making this strategic decision, the board and IT leaders should collectively answer some fundamental questions. The answers to these will clearly indicate which path is more realistic and beneficial for the company.

Risk question: What is a greater risk – entrusting part of the operation to a trusted, third-party partner, or attempting to build a complex operation on your own with a high probability of costly mistakes?

Cost question: Have we done a solid TCO analysis for building our own SOC for at least 3 years? Are we ready for such a large, multi-year financial commitment?

The people question: are we able to compete in the job market for the best security analysts? How will we handle the inevitable turnover and knowledge retention within the team?

Timing question: How soon do we need to get a mature detection and response capability? Can we afford 12-18 months of building and tuning an internal team, or do we need protection “right now”?

Competency question: Is cyber security our core business? Do we really want and know how to build and manage a world-class operation, or is it better to focus on what we do best and entrust security to specialists?
