A CSIRT, or Computer Security Incident Response Team, is a group of professionals responsible for identifying, managing, and responding to cybersecurity incidents within an organization. Their main tasks include monitoring networks for threats, analyzing security breaches, coordinating responses to cyberattacks, and helping to minimize damage. CSIRTs also provide guidance on preventing future incidents and may communicate with external parties, such as law enforcement or other organizations, during major security events. By acting quickly and efficiently, CSIRTs play a crucial role in protecting sensitive data and maintaining business continuity.
