If you are navigating the world of cybersecurity, you have probably come across the term '(managed) SIEM'. In a job vacancy, a conversation with IT partners, or perhaps in a report that landed on your desk. But what exactly is it and why is it so important? Don't worry: you really don't need to be a security expert to understand this. In this blog, we explain what SIEM actually is. In plain English. Tible keeps IT human!

What does SIEM stand for?

SIEM stands for Security Information and Event Management. That sounds more complicated than it is. Simply put, a SIEM platform is a central place where all security information of an organization comes together. The system continuously collects and analyzes data from servers, applications, networks, and cloud environments.

This gives your organization real-time visibility into what is happening within your digital infrastructure, including your website, tools, and apps. Thanks to this overview, you can quickly detect any anomalies so you can intervene before an incident escalates into, for instance, a hack.

What is managed SIEM?

With managed SIEM, you outsource the monitoring of your digital infrastructure. An external IT partner becomes responsible for detecting and taking action in the event of an anomaly. This is convenient because properly setting up and maintaining SIEM requires specific expertise and continuous attention.

In addition, compliance – adhering to laws and regulations – plays an increasingly prominent role. A well-configured SIEM system ensures that relevant events are properly logged and documented, in line with standards such as ISO 27001 and the upcoming NIS2 obligations.

The ultimate goal? An infrastructure in which data, processes, and users are continuously monitored and verified, without sacrificing performance or scalability. In short: secure and user-friendly systems.

What is included in SIEM?

The system collects logs from the entire organization: from servers and applications to networks and users. Everything in one place.

Isolated signals often reveal little. A SIEM platform analyzes data from multiple systems simultaneously and searches for patterns. This makes threats visible that you would otherwise miss.

Everything is monitored continuously via a central dashboard. In case of suspicious activity, automated alerts are triggered and direct action is taken where necessary.

Detected incidents are automatically recorded and forwarded to security experts for evaluation. This ensures no warning goes unnoticed.

In addition to monitoring, the infrastructure is actively reinforced. Using tools such as Nessus and SonarQube, supplemented by regular manual reviews and vulnerability scans, security is continuously tightened.

What is the difference between a SOC and a SIEM?

A SOC and a SIEM often go hand in hand, but they are not the same thing. The SOC - Security Operations Center - is the team or function that monitors, investigates, and follows up on security incidents. A SIEM is the software that supports this by collecting log data, recognizing suspicious patterns, and generating alerts. The SOC uses the SIEM as a tool to detect and react to suspicious activity faster.

And then we have 'SOC 2'. This is neither an operational security team nor software, but an audit report that demonstrates an organization's security processes and controls are properly set up. A SOC and SIEM can therefore contribute to SOC 2 compliance by proving how security monitoring and incident response work in practice.
