What is a SOC (Security Operations Center)?

The SOC (Security Operations Center) is a monitoring center dedicated to the surveillance, detection, analysis, and management of cybersecurity incidents. It relies on advanced technologies and cybersecurity experts to continuously monitor an organisation’s IT (Information Technology) and OT (Operational Technology) environments.

Through constant monitoring of security events, the SOC identifies abnormal behavior, detects potential cyberattacks, and supports teams in responding to incidents before they impact business operations.

Specifically, the SOC collects and correlates data from networks, servers, workstations, applications, industrial equipment, and security systems. Analysts monitor alerts in real time, assess threats, investigate incidents, and coordinate remediation efforts to protect critical assets and ensure business continuity.

Why use a SOC?

The SOC is an essential pillar of the cybersecurity strategy for organisations facing constantly evolving cyber threats and regulatory requirements. Its main benefits are:

• Continuous 24/7 monitoring to detect threats before they impact critical operations.

• Rapid incident detection through intelligent correlation of security events and real-time analysis.

• Reduction of operational risks by limiting potential impacts on production, critical infrastructure, and essential services.

• Improved IT/OT visibility through centralised monitoring of IT and industrial environments.

• Enhanced cyber resilience through proactive identification of anomalies and suspicious behavior.

• Easier regulatory compliance by meeting the requirements of standards and regulations such as NIS2, ISO 27001, GDPR, and the LPM.

• Effective cybersecurity management through dashboards, metrics, and reports that track changes in the security posture.

• Access to specialised expertise in IT and industrial OT cybersecurity, without having to build a dedicated in-house team.

Concrete examples of SOC usage

• Detection of abnormal network activity: the SOC quickly identifies suspicious behavior or intrusion attempts before they compromise critical systems.

• Protection of industrial environments: continuous monitoring of OT networks, PLCs, and industrial equipment to prevent production disruptions caused by a cyberattack.

• Coordinated management of cybersecurity incidents: analysis of alerts, threat assessment, and support for teams in response and remediation efforts.

• Securing critical infrastructure: monitoring of sensitive facilities in the energy, transportation, public services, and essential operator sectors.

• Monitoring of international multi-site environments: centralising cybersecurity visibility across all of the company’s infrastructures, regardless of their geographic location.

• Anticipating emerging threats: using threat intelligence to more quickly detect attacks targeting a specific industry.

In summary

The SOC is a key mechanism for continuously monitoring IT and OT environments to detect cyber threats, respond effectively to incidents, and strengthen the organisation’s resilience. By combining human expertise, advanced monitoring tools, and 24/7 surveillance, the SOC helps protect critical assets, reduce operational risks, and ensure business continuity in an increasingly challenging cybersecurity landscape.
