SIEM (Security Information and Event Management)

What is SIEM?

SIEM, short for Security Information and Event Management, is a cybersecurity solution that centralizes and analyses in real time the logs generated by an organization’s systems, applications, and devices. Its goal is to detect anomalous patterns and threats at an early stage.

What benefits does it offer businesses?

SIEM enhances visibility across the technology infrastructure and improves the detection of security incidents. It enables organizations to correlate disparate events, reduce response times, and comply with audit and data protection regulatory requirements. It is especially valuable in complex and highly regulated environments.

How is it applied in practice?

It collects information from multiple sources (servers, networks, applications, and security devices) and applies analytical rules or algorithms to identify potential attacks. Security teams (SOC) rely on SIEM as a key tool to investigate, prioritise, and respond to incidents.
