Trump Proposes $707M Cut to CISA Budget, Sparking Cybersecurity Concerns

The US Cybersecurity and Infrastructure Security Agency faces another significant budget reduction under President Trump's proposed fiscal year 2027 spending plan, which would slash $707 million from the agency's operations.

This proposed cut comes on top of substantial reductions CISA has already experienced during Trump's second term. The agency has lost approximately one-third of its workforce—nearly 1,000 employees—and millions in funding since January 2025.

"Refocusing" on Core Mission

The administration frames the budget reduction as a "refocus" on CISA's core mission, arguing the agency has become "more focused on censorship than on protecting the Nation's critical systems." The proposal specifically targets programs related to misinformation, propaganda, and external engagement.

According to the budget document, CISA would eliminate "offices that are duplicative of existing and effective programs at the State and Federal level, such as certain targeted school safety programs." It would also cut "programs focused on so-called misinformation and propaganda as well as external engagement offices such as council management, stakeholder engagement, and international affairs."

Programs Already Eliminated

Many of the targeted programs have already been dismantled. On his first day back in office, President Trump eliminated all Department of Homeland Security advisory committees, including:

• The Cyber Safety Review Board
• The Artificial Intelligence Safety and Security Board
• The Critical Infrastructure Partnership Advisory Council
• The National Security Telecommunications Advisory Committee
• The National Infrastructure Advisory Council
• The US Secret Service Cyber Investigations Advisory Board

These cuts followed earlier eliminations, including the termination of $10 million in funding for the Multi-State Information Sharing and Analysis Center (MS-ISAC) in March 2025, and the severance of ties with the Center for Internet Security six months later.

Cybersecurity Experts Sound Alarm

A former CISA official, speaking anonymously due to fear of political repercussions, warned that the proposed cuts would "weaken the system for managing cyber risk."

"Managing cyber risk to critical infrastructure requires coordination across federal agencies, [State, Local, Tribal, and Territorial] governments, private operators, and international partners," the official explained. "The offices targeted here enable that coordination by supporting shared awareness, early warning, and aligned response. Eliminating external engagement and international functions will further degrade that coordination."

The official emphasized that if enacted, the budget cuts would "increase the likelihood that preventable incidents escalate into disruptions affecting critical infrastructure and the services Americans depend on."

Congressional History with CISA Funding

This isn't the first time Trump has proposed deep cuts to CISA. His fiscal year 2026 budget sought to eliminate approximately $491 million from the agency's spending. However, Congress ultimately approved a more modest reduction of about $135 million.

Whether Congress will approve the more aggressive $707 million cut remains uncertain, but the proposal signals the administration's continued skepticism toward CISA's broader mission beyond traditional cybersecurity defense.

The Department of Homeland Security, which oversees CISA, has not responded to requests for clarification about plans to cut programs that have already been eliminated.

As cyber threats continue to evolve and increase in sophistication, the debate over CISA's role and resources highlights the tension between traditional cybersecurity functions and newer concerns about information integrity and election security.
