The White House’s fiscal year 2027 budget proposal would cut about $707 million from the Cybersecurity and Infrastructure Security Agency, shrinking the agency by roughly 30% and narrowing its mission to federal civilian network defense and critical infrastructure protection. Budget documents and reporting say the plan would reduce spending on personnel, contractors, equipment, mission support, stakeholder engagement, and international affairs, while also eliminating CISA’s election security program and ending support for the Elections Infrastructure Information Sharing and Analysis Center. The proposal also restructures some Department of Homeland Security functions, including changes tied to the Office of Countering Weapons of Mass Destruction, while preserving selected technical efforts such as CIRCIA implementation and cybersecurity planning support for the 2028 Los Angeles Olympics.
The proposed cuts have drawn warnings from state officials, industry groups, former agency personnel, and cybersecurity experts who say CISA’s reduced role could weaken threat intelligence sharing, incident response coordination, election security assistance, and cross-sector risk management. Multiple reports note that CISA has already faced layoffs, funding pressure, and leadership instability, and critics argue that further reductions could fragment national cyber defense at a time of continued intrusions linked to Russia, China, and Iran and growing concern over AI-enabled threats. The administration says the changes would eliminate waste, duplicative programs, and activities tied to misinformation work, but the final budget is expected to face significant congressional scrutiny.

Health-ISAC published an analysis of the administration's FY2027 budget request and congressional justifications, highlighting the proposed $707 million CISA cut and reductions at HHS while noting some cybersecurity-related programs would remain flat or be reorganized.

Reporting on the FY2027 proposal said it would eliminate CISA's election security program, end support for the Elections Infrastructure ISAC, reduce stakeholder engagement and international affairs functions, and cut positions tied to chemical security and other programs. The same proposal also preserved some technical cybersecurity work and included funding for CIRCIA implementation and 2028 Los Angeles Olympics cybersecurity planning.
The Trump administration's fiscal year 2027 budget proposal called for cutting about $707 million from CISA, reframing the agency around federal civilian network defense and critical infrastructure protection while reducing broader engagement and related programs.
