The IT systems of modern companies are highly connected, distributed, and dynamic. Cloud services, SaaS applications, home office, different locations, and external partners expand digital value creation – but also increase the attack surface. Consequently, the number and complexity of cyberattacks are increasing, as are regulatory requirements and expectations for rapid response capabilities.

This is precisely where a Security Operations Center (SOC) comes in. Serving as a central unit for security monitoring, threat analysis, and the initiation of initial emergency measures, the Security Operations Center forms the operational heart of cyber defense.

But what exactly is a SOC? What tasks does it actually perform? And how can you successfully set it up or outsource it to a managed SOC in practice? In this article, you will learn how to strategically plan, efficiently implement, and successfully operate a SOC in the long term.

What Is a Security Operations Center (SOC) and Why Is It Indispensable Today?

A Security Operations Center is much more than a technical monitoring system or a pure SIEM platform. A SOC is an organizational and operational unit that centrally monitors, analyzes, and coordinates security events. The key lies in the interaction between people, clearly defined processes, and powerful technologies.

The central tasks of a Security Operations Center include:

• continuous monitoring of security-related events
• detection of attacks and anomalies
• structured processing of security alerts
• provisioning of situational overviews and reports for management and specialist departments
• continuous improvement of detection and response capabilities

A professionally operated SOC thus forms the operational heart of cyber defense.

Why is a SOC indispensable for companies today?

• The answer lies in the changing IT landscape. Modern companies are increasingly working:
• decentralized across multiple locations
• with cloud and hybrid infrastructures
• with external partners, suppliers, and service providers
• with mobile workplaces and remote access
• with increasing regulatory pressure and ever stricter compliance requirements

A clearly defined network perimeter no longer exists in practice. Today, systems, identities, and data are distributed across different zones, cloud services, locations, and external partners. Attacks no longer occur only via obvious vulnerabilities, but often via compromised identities, third-party access, or misconfigurations of security-relevant components.

At the same time, regulatory pressure is increasing. Requirements such as the NIS2 Directive, the Digital Operational Resilience Act (DORA), the Cyber Resilience Act (CRA), and, in Switzerland, the Information Security Act (ISG) increasingly require companies to demonstrate verifiable capabilities for continuous monitoring, rapid detection, and structured handling of security incidents. Cybersecurity is thus becoming not only a technical obligation, but also an organizational and regulatory one. Companies must be able to prove that they actively monitor risks and promptly detect and appropriately handle incidents.

Advantages of a Security Operations Center (SOC)

A Security Operations Center creates transparency. It correlates security-related events centrally, identifies risks early on, and ensures a coordinated response to incidents.

For the management, a Security Operations Center means above all predictability and control. Risks are not only addressed in crisis mode, but continuously monitored and proactively managed. Responsibilities are defined, processes are established, and potential damage can be significantly reduced.

A common real-life scenario shows just how crucial this transparency is:If the SOC detects a compromised user account of an external service provider early on, access can be blocked immediately and lateral movement within the network can be prevented before business-critical systems are affected or reportable incidents occur.

What Type of SOC Is Suitable for Our Company and What Services Do We Really Need?

As clear as the benefits of a Security Operations Center are, the various solutions are just as diverse – because companies can set up their SOC in different ways:

• Internal SOC – everything in the company, full control, high resource requirements
• Managed SOC / external SOC – outsourced expertise, rapid scalability
• Hybrid SOC – combination of internal teams and external service providers

Alongside the operating model, a company must also consciously decide which SOC services they need. These include, for example, security monitoring, use case coverage, threat hunting, incident response, threat intelligence, digital forensics, or vulnerability management.

A common mistake is to adopt concepts or providers one-to-one. An effective SOC is always customized and risk-based, and the appropriate form depends on the own organization. This raises the question: What services are really needed, and how must the SOC be tailored to the company’s systems, processes, and critical assets?

Foundation for a Tailor-Made SOC: Understanding the Organization

It is therefore crucial to first have a clear understanding of the company’s IT landscape and processes:

• What does our IT landscape look like?
• Where are our systems and data located?
• Which assets and business processes are critical?
• Which (security) technologies do we use?
• Which cloud and SaaS services are connected?
• Which external partners, suppliers, or service providers have access to our systems?
• Which regulatory requirements do we have to meet?
• What are the possibilities that exist for automation and AI-supported analysis, for example for alarm enrichment, prioritization, or the initiation of immediate measures?

A SOC can only monitor and protect what is known, connected, and reasonably prioritized. That is why the entire attack surface must be considered, because it does not end at the company’s boundaries. External partners, suppliers, and service providers also represent potential entry points for attacks.

Special attention should be paid to:

• business critical assets (systems, data, identities)
• privileged access
• external interfaces and APIs
• remote access and third-party connections
• Only after it has been determined which assets are particularly worthy of protection and which attack vectors can be used to reach them, it is possible to define meaningful monitoring scenarios. A SOC does not automatically protect everything equally, but should always be structured on a risk-based approach.

SOC Preliminary Study: From Analysis to Concrete Target Vision

Once a clear understanding of the company’s organization, critical assets, and IT landscape has been established, the specific SOC requirements must be defined. A SOC preliminary study has proven useful here: it creates the basis for a customized Security Operations Center.

The aim of the preliminary study is to jointly develop a precise target vision:

• Which SOC services are necessary and which are not?
• Which risks should be addressed?
• What are the expectations regarding response times, reports, and responsibilities?

At the same time, a common understanding of the company’s IT landscape, relevant perimeters, business-critical assets, and connected partners and service providers is developed. Only when these fundamentals are transparent is it possible to define meaningful monitoring scenarios and realistic requirements for a SOC.

The preliminary study also provides a solid basis for internal decisions and subsequent procurement steps. Based on the target vision, requirements can be structured and incorporated into a request for quotation or formal tender. This clearly describes services, service levels, and responsibilities, makes it possible to compare offers from different providers, reduces the likelihood of wrong decisions, and ensures that the chosen SOC operating model is optimally tailored to the organization, both technically and economically.

Our SOC Consulting Service supports companies in precisely this process. Our experts accompany you through the SOC preliminary study, work with you to define the appropriate services, and ensure that your SOC is tailored to your specific risks, assets, and processes.

How Can a SOC Be Successfully Implemented? Our Practical Tips

In practice, SOC projects rarely fail because of the technology used. More often, the cause is unclear expectations, a lack of governance, or insufficient preparation. With our practical tips, we show how companies can effectively introduce a Security Operations Center and operate it successfully in the long term.

Clearly Defining Detection – Which Attacks Are to Be Detected by the SOC?

One of the key questions is: What is actually detected by the Security Operations Center and how reliable is it? Many companies assume that a SOC automatically detects all relevant attacks. In reality, the detection capability heavily depends on:

• defined use cases
• connected log sources
• the quality of the data
• the clarity of the requirements

Practical tip: Frameworks such as MITRE ATT&CK help to describe detection scenarios in a structured way and reveal gaps. It is important that coverage is tailored to the company’s architecture and the relevant threat scenarios – not to theoretical completeness.

Planning of Onboarding and Log Data Strategy

Another critical point is the onboarding phase. This is often where it is decided whether a SOC will deliver long-term added value or become an alarm factory. Not all systems need to be connected at the same time, and not all logs are equally relevant.

Practical tip: Consider the following questions during onboarding:

• Which log data do we really need for our use cases?
• Does all log data have to be stored for the same amount of time? What are the regulatory requirements?
• Which logs belong in the hot storage / analytics workspace and which in cold storage?
• How do we deal with costs and performance?
• A clear log data strategy ensures that the SOC works efficiently, costs remain controllable, and security increases measurably.

SOC Tendering, Integration, and Operation

Careful and targeted preparation avoids many potential short- and long-term issues. We therefore recommend preparing the following steps:

• Structured requests for proposals or formal tender documents enable comparable offers, transparent evaluations, and realistic expectations of performance and costs.
• Selection is followed by integration: coordinating processes, checking SLAs, and gradually transferring them into regular operation.
• Regular reviews, continuous improvement processes, tests, and exercises ensure the long-term performance of the SOC.

This makes it possible to plan the introduction and operation of a SOC, design it efficiently, and adapt it to the company’s requirements – from the definition of use cases to the log data strategy to the operation.

Conclusion: A SOC Is Not Just a Service, But a Continuous Process

A Security Operations Center is not a one-time project or a tool that you can “just buy”. It is a continuous process that has a profound impact on the organization. The key to success lies in a clear understanding of the company’s IT landscape, business-critical assets, and relevant attack vectors, including external interfaces, partners, and service providers.

Companies that take the time to define their requirements in a structured manner lay the foundation for an effective, sustainable SOC. They avoid wrong decisions, reduce risks, and gain the transparency that is essential in an increasingly digital and networked world.

A SOC does not protect the entire IT system across the board, but rather specifically those scenarios that a company has understood, prioritized, and ultimately implemented with a provider.
