The Cybersecurity and Infrastructure Security Agency (CISA) is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and information technology infrastructure protection. It oversees all levels of the federal government and coordinates with U.S. states to improve cybersecurity against private and nation-state hackers. The CISA is headquartered in Arlington, Virginia.

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.
