When analyzing the requirements of the NIS2 directive and amendments to the National Cybersecurity System Act, it’s easy to focus on formal obligations: documentation, policies, procedures. However, looking at these regulations from the perspective of the obligation to report serious incidents within 24 hours, the topic starts to look far more pragmatic than formal.
Incident reporting is not simply a matter of sending an email stating that “something happened.” In practice, an organization should already possess precise knowledge at an early stage about what exactly the incident involved, what its source was, what impact it has on business services provided, and what potential impact it may have on the economic environment and supply chain. This fundamentally changes the perspective on regulatory requirements.
What Does the 24-Hour Reporting Deadline Really Mean?
The 24-hour deadline for initial reporting of a serious incident sounds like a simple administrative requirement. In reality, it’s a mandate to possess operational capabilities that most organizations don’t have today. To prepare a meaningful report within a day, an organization must detect the incident, conduct preliminary analysis, determine scope and impact, and formulate a report meeting regulatory requirements – all within that timeframe.
Each of these steps requires not only competencies but above all access to appropriate data and analytical tools. Without centralized collection and correlation of logs from IT and OT systems, determining the source and scope of an incident within a few hours is practically impossible. Analysts must be able to quickly trace the attack path, identify compromised systems, and assess which business services have been affected.

What Information Does the Regulator Require in an Incident Report?
Serious incident reporting is not a form to check off. The regulator expects specific information that will allow assessment of the threat scale and enable coordinated response actions. The organization must be able to determine the nature of the incident – whether we’re dealing with a ransomware attack, data breach, system compromise, or sabotage. Each of these scenarios requires different classification and different response procedures.
Determining impact on services is also crucial. How many systems have been affected? How many users or customers are impacted? Are critical services still available? These questions require immediate answers, and providing them without real-time visibility into infrastructure status is impossible.
The regulator will also ask about potential cross-border impact and supply chain effects. If your organization provides services to other regulated entities or is part of a critical supply chain, an incident at your organization may have cascading consequences. Assessing this impact requires current knowledge of business and technical dependencies.
Why Traditional Security Approaches Are No Longer Sufficient
Many organizations still operate in a reactive model – incidents are detected accidentally, analyzed ad hoc, and knowledge about infrastructure is scattered among different teams and systems. In such a model, meeting KSC/NIS2 incident reporting requirements is not just difficult – it’s practically impossible.
Without automated log correlation from various sources, analysts spend hours manually searching through data from individual systems. Without current IT and OT asset inventory, it’s impossible to quickly determine which systems may have been affected. Without defined BIA (Business Impact Analysis), assessing impact on business services becomes subjective opinion rather than objective assessment. Without a supplier dependency map, answering questions about supply chain impact requires tedious consultations and guesswork.
What Operational Capabilities Are Essential?
To realistically meet requirements regarding response time and reporting information quality, an organization needs several key capabilities. The first is continuous security event monitoring – reviewing logs once daily or responding only to antivirus alerts is not enough. The capability to detect anomalies in real-time, correlate events from various sources, and identify potential incidents at an early stage is essential.
The second capability is rapid incident analysis and classification. When something happens, the team must be able to determine within hours – not days – the nature of the event, its scope, and potential consequences. This requires both appropriate tools (SIEM, SOAR, analytical platforms) and competent analysts available on a continuous basis.
The third capability is current contextual knowledge. Analysts must have access to current asset inventory, system dependency maps, BIA analysis, and information about critical suppliers. Without this context, even the best technical analysis won’t allow for complete business impact assessment.
Do Regulations Require Having a SOC?
Formally, KSC/NIS2 regulations don’t explicitly require having a Security Operations Center. The regulator speaks of obligations to monitor, detect, and respond to incidents, but doesn’t mandate a specific organizational model. This apparent flexibility can be misleading.
In practice, meeting requirements regarding response time, analysis quality, and reporting information completeness without mature security event monitoring and analysis mechanisms is very difficult to achieve. A SOC – whether internal or external in a SOC as a Service model – is a natural response to these requirements. It’s not a matter of formal compliance, but of operational capability to fulfill real obligations.
How Does SOC Support Reporting Obligations?
A mature SOC delivers exactly the capabilities that regulations require. Continuous 24/7 monitoring means incidents are detected immediately, not after days or weeks. Automated log correlation enables rapid identification of incident scope. SIEM and SOAR platforms enable systematic analysis and documentation of events in the format required by the regulator.
SOC also maintains current contextual knowledge – asset inventory, dependency maps, response playbooks for various incident types. When an event occurs, analysts don’t start from scratch but use prepared procedures and tools. This is the difference between chaotic reaction and professional incident management.
Equally important is the ability to generate reports compliant with regulatory requirements. SOC can automatically prepare reports containing all required information in the appropriate format and within deadlines. This eliminates the risk of missing deadlines or delivering incomplete reports.
Internal Model or SOC as a Service?
Organizations face a choice: build their own SOC or use external provider services. Both models have their advantages and limitations, and the choice depends on organization size, available resources, and industry specifics.
An in-house SOC provides full control and deep environmental knowledge, but requires significant investment in infrastructure, tools, and above all, staff. Maintaining a competent team of analysts working 24/7 is a staffing and financial challenge, especially given the current specialist shortage in the market.
SOC as a Service offers access to mature processes and experienced analysts without having to build everything from scratch. A good provider also brings experience from serving many clients – they see more incidents, know more attack patterns, and respond faster to new threats. However, it’s crucial to choose a provider who understands KSC/NIS2 regulatory specifics and can support the organization in fulfilling reporting obligations.
What Else Besides SIEM Monitoring Belongs to Maintaining Compliance?
KSC/NIS2 emphasises the resilience of the whole organisation, and monitoring technology is only one of its pillars. The other two are people and external suppliers — and both require continuous work rather than a one-off project.
The first area is a security culture programme. The best EDR will not help if employees routinely click on phishing links. Regular simulated social engineering tests combined with training assigned to those who were caught out create a repeatable “test — measure — train” cycle.
The second area is continuous supplier risk management. A supplier assessment carried out during KSC/NIS2 implementation ages: a supplier may change its security practices, be acquired or suffer its own breach. You need a process of periodic re-assessment of the supply chain — its elements are described in the article on ICT supply chain security and vendor audits.
Regular testing and follow-up audits close the loop. The IT environment keeps changing — new systems arrive, configurations drift from the baseline — so a risk analysis and tests from a year ago no longer describe the actual state.
How Do You Prove to the Board and the Regulator That Compliance Is Maintained?
Maintaining compliance is, in practice, a continuous supply of evidence of due diligence, and that evidence takes the form of reports. SOC monitoring reports show how many alerts there were, how many turned out to be incidents and what the response time was. Phishing campaign reports show how employee susceptibility changes over time. Supplier assessment reports demonstrate supply chain management, and penetration test and vulnerability scan results demonstrate management of technical gaps.
The same reports serve two audiences. For the regulator they are evidence in case of an inspection. For the board they are a decision-making tool: they show risk trends and the effectiveness of the measures taken. Without measurable data security remains an abstraction; with reports it becomes an area that can be managed.
A Pragmatic Approach to Compliance
The discussion about whether SOC is “required” by regulations is essentially academic. The practical question is: how does the organization intend to meet requirements for detecting, analyzing, and reporting incidents within legally specified timeframes? Without appropriate operational capabilities, these obligations will remain on paper, and the organization will be exposed to sanctions not for lacking SOC, but for failing to meet specific requirements that SOC helps fulfill.
Investment in incident monitoring and response capabilities is not a compliance cost – it’s an operational security cost that happens to align with regulatory requirements. Organizations that approach the topic pragmatically treat KSC/NIS2 as an opportunity to build real cybersecurity capabilities, not just another checkbox to tick.
The deadline is a detection requirement
Nothing in the regulation obliges an organisation to run a security operations centre. What it obliges is reporting a significant incident within 24 hours of becoming aware of it — and an organisation cannot report what it has not noticed. Since intrusions do not respect office hours, that duty translates into somebody watching alerts at three in the morning, which is a staffing statement rather than a technology one.
Where that rota cannot be filled internally, the capability is bought: SOC as a Service.

Frequently asked questions
Does KSC/NIS2 require having a SOC?
Formally, KSC/NIS2 regulations do not explicitly require having a SOC. However, the 24-hour serious incident reporting obligation, quality requirements for reports, and the need for continuous monitoring make it practically impossible to meet these requirements without mature monitoring mechanisms.
What does the 24-hour incident reporting deadline under KSC/NIS2 mean?
Within 24 hours, an organization must detect the incident, conduct a preliminary analysis, determine the scope and impact on business services, and formulate a report for the regulator. This requires continuous monitoring, centralized log collection, and competent analysts available 24/7.
Internal SOC or SOC as a Service — which to choose?
An in-house SOC provides full control but requires significant investment in infrastructure and a 24/7 team. SOC as a Service offers access to mature processes and experienced analysts without building everything from scratch. The choice depends on the organization's size, available resources, and industry specifics.
What operational capabilities are essential for KSC/NIS2 compliance?
An organization needs three key capabilities: continuous real-time security event monitoring, rapid incident analysis and classification (in hours, not days), and current contextual knowledge — asset inventory, system dependency mapping, and BIA analysis.
