The united State CERT provides cybersecurity protection to Federal, civilian, and executive branch agencies through intrusion detection and prevention capabilities. Which type of incident response tea

A PSIRT (Product Security Incident Response Team) addresses vulnerabilities in specific vendor products, not nationwide governmental cybersecurity protection.

National PSIRT is not a recognized standard team classification; PSIRT is inherently product- and vendor-scoped, not national in mission.

A National CSIRT operates at the country level, coordinating incident response and providing protective services to national infrastructure, government agencies, and civilian networks across the entire nation. US-CERT, now operating under CISA, fits this classification by serving federal, civilian, and executive branch entities nationwide rather than a single parent organization. The CSIRT designation is correct because the mission covers broad incident handling, not vendor product vulnerabilities.

Federal CSIRT is not the standard industry-recognized classification for a country-level team; the accepted term for this scope is National CSIRT.
