CERT / CSIRT
A team specialised in preventing and handling cybersecurity incidents.
A CSIRT (also called a CERT) is a team tasked with preventing and managing security incidents for a given perimeter: an organisation, a sector or a country. It monitors threats, raises alerts, coordinates the response to attacks and shares information. In France, the CERT-FR is operated by ANSSI, complemented by sector-specific and regional teams.
