The Cybersecurity and Infrastructure Security Agency (CISA) leads the national effort to defend critical infrastructure against the threats of today, while working with partners across all levels of government and in the private sector to secure against the evolving risks of tomorrow.
On November 16, 2018, President Trump signed into law the Cybersecurity and Infrastructure Security Agency Act of 2018. This landmark legislation elevated the mission of the former National Protection and Programs Directorate (NPPD) within DHS and established CISA.

CISA Vision and Mission
A safe, secure, and resilient infrastructure where the American way of life can thrive.
We lead the national effort to protect and enhance the resilience of the nation's physical and cyber infrastructure.
CISA's divisions include:
CISA’s Cybersecurity division works with government and private sector customers to ensure the security and resilience of the Nation’s cyber infrastructure. The division includes the National Cybersecurity Communications Integration Center (NCCIC), the Nation’s flagship cyber defense, incident response and operational integration center.
Through the Emergency Communications division, CISA enhances public safety interoperable communications at all levels of government, providing training, coordination, tools and guidance to help partners across the country develop their emergency communications capabilities.
The Infrastructure Security division coordinates security and resilience efforts using trusted partnerships across the private and public sectors, and delivers training, technical assistance, and assessments to federal stakeholders as well as to infrastructure owners and operators nationwide.
The National Risk Management Center (NRMC) is CISA’s planning, analysis, and collaboration center. It works to identify and address the most significant risks to our nation’s critical infrastructure.
The Federal Protective Service protects federal facilities, their occupants, and visitors by providing superior law enforcement and protective security services, and by leveraging our access to the intelligence and information resources of our network of federal, state, local, tribal, territorial, and private sector partners.
