The threats we face—digital and physical, man-made, technological, and natural—are more complex, and the threat actors more diverse, than at any point in our history. CISA is at the heart of mobilizing a collective defense as we lead the Nation’s efforts to understand and manage risk to our critical infrastructure.

Our partners in this mission span the public and private sectors. Programs and services we provide are driven by our comprehensive understanding of the risk environment and the corresponding needs identified by our stakeholders. We seek to help organizations better manage risk and increase resilience using all available resources, whether provided by the Federal Government, commercial vendors, or their own capabilities.



Lead the National effort to understand and manage cyber and physical risk to our critical infrastructure.



A secure and resilient critical infrastructure for the American people

What We Do

CISA builds the national capacity to defend against cyber attacks and works with the federal government to provide cybersecurity tools, incident response services and assessment capabilities to safeguard the ‘.gov’ networks that support the essential operations of partner departments and agencies.

We coordinate security and resilience efforts using trusted partnerships across the private and public sectors, and deliver technical assistance and assessments to federal stakeholders as well as to infrastructure owners and operators nationwide. CISA also delivers insights on these assessments related to current capabilities to identify gaps, which—along with an examination of emerging technologies—help determine the demand for future capabilities (both near- and long-term).
CISA enhances public safety interoperable communications at all levels of government to help partners across the country develop their emergency communications capabilities.

Working with stakeholders across the country, CISA conducts extensive, nationwide outreach to support and promote the ability of emergency response providers and relevant government officials to continue to communicate in the event of a natural disaster, act of terrorism, or other man-made disaster.

The National Risk Management Center (NRMC) is housed within the Cybersecurity and Infrastructure Security Agency (CISA). NRMC is a planning, analysis, and collaboration center working to identify and address the most significant risks to our nation’s critical infrastructure.

NRMC works in close coordination with the private sector and other key stakeholders in the critical infrastructure community to: Identify; Analyze; Prioritize; and Manage the most strategic risks to our National Critical Functions—the functions of government and the private sector so vital to the United States that their disruption, corruption, or dysfunction would have a debilitating impact on security, national economic security, national public health or safety, or any combination.
