Return to United States Computer Emergency Readiness Team (US-CERT) or United States Computer Emergency Readiness Team (US-CERT)
The Cybersecurity and Infrastructure Security Agency (CISA), headquartered in Arlington, Virginia, is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and infrastructure protection across all levels of government, coordinating cybersecurity programs with U.S. states, and improving the government's cybersecurity protections against private and nation-state hackers.
The agency began in 2007 as the National Protection and Programs Directorate (NPPD). With the Cybersecurity and Infrastructure Security Agency Act of 2018, CISA's footprint expanded to include roles protecting the census, managing National Special Security Events, and the U.S. response to the COVID-19 pandemic. It has also been involved in overseeing 5G network security, securing elections, and strengthening the US grid against electromagnetic pulses (EMPs). The Office for Bombing Prevention leads the national counter-IED effort.
