What is a Security Operations Center (SOC)?
A Security Operations Center (SOC) is the team, processes, and technology that monitor your IT environment 24/7. The goal is to detect, analyze, and respond to cyber threats in a timely manner.
A SOC relies on people, processes, and technology working together. Technology provides visibility, but analysts determine what a signal really means and what action is required.
The core task is simple to define. A SOC reduces the time between a breach and its discovery, ensuring that damage remains limited.
That time costs money when things go wrong. According to IBM (Cost of a Data Breach 2024), the global average cost of a data breach in 2024 was $4.88 million. That is 10% higher than the previous year.
Why is a SOC important?
Attackers do not stick to office hours. Without continuous monitoring, you often only notice a threat once the damage is already visible.
Rapid detection limits that damage and the costs. The sooner you spot an attack, the smaller the chance that an attacker can move quietly through your network.
The threat is concrete and current in the Netherlands. According to the NCSC, there were at least 121 unique ransomware incidents in the Netherlands in 2024 (project Melissa).
People also play a major role in incidents. According to the Verizon DBIR 2024, 68% of data breaches involve a non-malicious human element in data breaches: an error or a victim of social engineering.
A SOC catches exactly those kinds of moments. It recognizes anomalous behavior that a firewall or virus scanner alone would not see.
What does a SOC do? The four core tasks
A SOC operates in a fixed, continuous cycle. Each phase feeds the next, ensuring your environment is better protected after every signal.
At Aumatics, this cycle consists of four core tasks with fixed processes and SLAs. We will walk through them one by one below.
Monitoring and log collection
Everything starts with visibility into what is happening. The SOC collects real-time logs from endpoints, firewalls, cloud, and identity, even outside office hours.
That data comes together in a SIEM. SIEM stands for Security Information and Event Management: a system that collects, correlates, and visualizes log data.
Correlation is the keyword here. The SOC links disparate signals from various sources, such as XDR for correlated detection. This brings suspicious patterns into view.
Triage and classification
Not every alert is a genuine attack. Analysts assess each signal—a process known as triage—to filter out the noise.
A significant portion of that noise consists of false positives. A false positive is an alert that looks like a threat but poses no real danger.
What remains is assigned a severity level from P1 to P4. Analysts then map the threat to MITRE ATT&CK. This is a knowledge base of known attack techniques, which clarifies exactly what the attacker is attempting to do.
Incident response and escalation
Once an incident is confirmed, immediate action follows. The SOC operates according to a pre-agreed escalation model, ensuring everyone knows their responsibilities.
This response is structured incident response. The SOC isolates the affected systems and conducts a forensic investigation, while keeping your organization informed throughout the process.
Speed is defined in the SLA. At Aumatics, our analysts address a P1 incident—the most severe category—within 15 minutes.
Detection engineering and improvement
The work doesn't stop after an incident. Analysts perform a root-cause analysis to determine how the threat entered the environment.
Based on these findings, they write new detection rules and refine existing ones. Aumatics uses the MITRE ATT&CK framework as a guide for this process.
In this way, every attack makes your environment more resilient. The next time a similar attempt occurs, it will be recognized much faster.
Who works in a SOC? The team
A SOC operates using a tiered analyst model. Each tier has specific responsibilities and escalates more complex issues to the next level.
In addition, security engineers and incident responders support the team. You can read more about these roles in our guide on the role of the SOC analyst.
A practical challenge is alert fatigue. When faced with too many signals, a team can become desensitized, which is precisely why triage and effective detection rules are so critical.
SOC vs. SIEM: what is the difference?
A SIEM is technology, while a SOC is the organization surrounding it. The SIEM collects and correlates log data, and the SOC team uses that data to make decisions and take action.
This distinction is important when making your choices. A SIEM without a SOC simply produces alerts that no one is there to assess.
In short, the SIEM is a tool in the hands of the SOC. You need both for effective detection.
Types of SOC: in-house, virtual, and managed
There are three ways to set up a SOC. The choice depends on your budget, your staff, and how quickly you need results.
A managed SOC is shared across multiple clients. This makes costs predictable and gives you immediate access to experienced analysts.
For many mid-market and enterprise organizations, a managed SOC is the realistic choice. You get mature detection without having to spend years building your own team.
Build your own SOC or outsource?
Building it yourself is possible, but it is demanding. You need to recruit and retain analysts, fill 24/7 rosters, implement a SIEM, and continuously invest in expertise.
The labor market makes this difficult. According to ISC2 (2024), the global shortage of security professionals stands at 4,763,963 people. That is an increase of 19.1% compared to 2023.
Outsourcing via a managed SOC or SOCaaS is the alternative. You get predictable costs and immediate access to expertise without having to build a team yourself.
Are you unsure which option to choose? These questions will help you decide:
Also consider a lighter alternative. Take a look at the difference between MDR and SOC, as Managed Detection and Response is sometimes a better fit for organizations without their own SOC.
SOC and compliance: NIS2, the Cyber Security Act, and GDPR
Continuous detection is becoming a compliance requirement for more and more organizations. What used to be a choice is now often an obligation.
NIS2, implemented in the Netherlands via the Cyber Security Act, requires demonstrable and timely detection and response. A SOC helps you put that into practice.
The stakes are high. The NIS2 Directive (Article 34) mandates that member states implement fines under the NIS2 Directive.
For essential entities, this involves a minimum of €10 million or 2% of the total worldwide annual turnover, whichever is higher.
Aumatics therefore provides audit-ready logging for ISO 27001, NIS2, and GDPR. This ensures you have proof of your detection and response whenever an auditor asks for it.
A SOC in practice: from reactive to detection-driven
Theory becomes truly clear with an example. An international manufacturing company with over 200 employees had no central logging, no SIEM, and no detection capability.
Through a gap analysis and step-by-step onboarding of the Managed SOC, that changed. The company enforced MFA, closed ports, and implemented a VPN.
Next came network segmentation, an EDR rollout, and a central SIEM. Finally, 24/7 SOC monitoring was implemented using a Zero Trust approach.
This is how the organization shifted from reactive to practical, detection-driven security. The impact became clear during an actual incident.
An employee fell for a phishing email. Conditional access blocked the login, and the SOC immediately spotted an anomalous pattern: failed and successful attempts from an unknown location.
The analysts intervened immediately. They blocked the session, reset the account, and notified the internal IT department.
That difference in response time is also financially measurable. IBM (2024) reports that internal detection results in a 61-day shorter breach lifecycle. This saves organizations nearly $1 million compared to breaches disclosed by an attacker.
