A SOC, or Security Operations Centre, is a team of experts responsible for continuously monitoring a company’s IT systems in order to detect, analyse and respond quickly to cyber threats. Its objective is to identify security incidents before they cause significant damage.
In many organisations, a SOC operates 24 hours a day, 7 days a week. Using advanced monitoring tools, it continuously analyses events from servers, computers, firewalls, networks, applications and security solutions such as EDR and XDR. This monitoring makes it possible to quickly identify unusual behaviour that may indicate an intrusion attempt, a data breach or the deployment of ransomware.
When suspicious activity is detected, SOC analysts assess the situation to determine whether it represents a genuine threat. If a cyberattack is confirmed, they act quickly to limit its impact: isolating an infected workstation, blocking a compromised account, preventing malware from spreading or supporting the company with incident management.
A SOC is not limited to responding to attacks. It also plays a key role in prevention by monitoring vulnerabilities, analysing emerging threats and recommending improvements to strengthen the long-term security of the organisation’s IT systems.
Not every company has its own SOC. Many choose to outsource this function to a specialist provider, giving them access to a team of experts and advanced monitoring tools without having to invest in an in-house infrastructure.
By providing continuous monitoring and a rapid response to incidents, a SOC is a key pillar of a modern cybersecurity strategy. It helps companies detect cyberattacks more quickly, limit their impact and maintain business continuity.
