CISA works with partners to defend against today’s threats and collaborates to build a more secure and resilient infrastructure for the future.
The Cybersecurity and Infrastructure Security Agency (CISA) leads the national effort to understand, manage, and reduce risk to our cyber and physical infrastructure. We connect our stakeholders in industry and government to each other and to resources, analyses, and tools to help them build their own cyber, communications, and physical security and resilience, in turn helping to ensure a secure and resilient infrastructure for the American people. Our 2021 Year in Review displays key examples of CISA’s work to carry out its mission in 2021, including milestones and accomplishments as the Agency advanced strategic priorities to maintain a secure and resilient infrastructure for the nation.
In Early September, CISA released the 2023–2025 CISA Strategic Plan, our first comprehensive strategy since the agency was established in 2018. The Strategic Plan is set against a risk landscape that encompasses an increasingly interconnected, global cyberspace in which the nation faces 24/7/365 asymmetric cyber threats with largescale, real-world impacts.
We lead the National effort to understand, manage, and reduce risk to our cyber and physical infrastructure.
A secure and resilient critical infrastructure for the American people.
We Are the Operational Lead for Federal Cybersecurity, or the Federal “dot gov”
CISA acts as the quarterback for the federal cybersecurity team, protecting and defending the home front—our federal civilian government networks—in close partnership with the Office of Management and Budget, which is responsible federal cyber security overall. CISA also coordinates the execution of our national cyber defense, leading asset response for significant cyber incidents and ensures that timely and actionable information is shared across federal and non-federal and private sector partners.
We Are the National Coordinator for Critical Infrastructure Security and Resilience
We look at the entire threat picture and work with partners across government and industry to defend against today’s threats while securing the nation’s critical infrastructure against threats that are just over the horizon.
Designed for Collaboration and Partnership
Established in 2018, CISA was created to work across public and private sectors, challenging traditional ways of doing business by engaging with government, industry, academic, and international partners. As threats continue to evolve, we know that no single organization or entity has all the answers for how to address cyber and physical threats to critical infrastructure. By bringing together our insight and capabilities, we can build a collective defense against the threats we face.
