Formed in 2007, the National Protection and Programs Directorate (NPPD) was a component of the United States Department of Homeland Security. NPPD's goal was to advance the Department's national security mission by reducing and eliminating threats to U.S. critical physical and cyber infrastructure.

On November 16, 2018, President Trump signed into law the Cybersecurity and Infrastructure Security Agency Act of 2018, which elevated the mission of the former NPPD within DHS, establishing the Cybersecurity and Infrastructure Security Agency (CISA). CISA is a successor agency to NPPD, and assists both other government agencies and private sector organizations in addressing cybersecurity issues.
