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) 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 DHS National Protection and Programs Directorate. With the Cybersecurity and Infrastructure Security Agency Act of 2018, CISA's footprint grew to include roles in securing elections and the census, managing National Special Security Events, and the U.S. response to the COVID-19 pandemic. It has also been involved in 5G network security and hardening the US grid against electromagnetic pulses (EMPs). The Office for Bombing Prevention leads the national counter-IED effort.
Currently headquartered in Arlington, Virginia, in 2025 CISA is planning to move its headquarters along with 6,500 employees to a new 10 story, 620,000 sq ft building on the consolidated DHS St. Elizabeths campus headquarters.
