Dear Chair Murray, Chairwoman Granger, Vice Chair Collins, and Ranking Member DeLauro:

We are a bipartisan cross-section of industry leaders, including former government officials, with significant national security, technology, critical infrastructure, and cybersecurity responsibilities who have worked with the Cybersecurity and Infrastructure Security Agency (CISA) and the Department of Homeland Security since their inception. We write today in our respective personal capacities to express our strong support for CISA and our concerns regarding proposed Fiscal Year 2024 (FY 2024) cuts to this critical national security agency.

As you know, CISA leads our national cybersecurity and critical infrastructure security efforts – an essential role responsible for countering dynamic and rapidly evolving attacks from threat actors like Russia, Iran, North Korea, and China – that regularly attack and breach U.S. Government agencies and critical infrastructures. Cuts to the FY 2024 funding level for CISA would weaken the agency’s important network defense efforts and critical infrastructure coordinator responsibilities.

Successful attacks against critical infrastructure have increased substantially in recent years. Organized criminal entities, foreign intelligence services and activist hackers are very real threats and constantly evolving. In the face of a known clear and present danger to the United States, now is the time to bolster our nation’s capabilities, not shirk our responsibilities to our citizens.

The U.S. is a cyber target and we must not stymie the progress that has been made to secure our most critical national assets. Proposed reductions would slow, if not halt, CISA’s efforts to deploy new cyber defense capabilities to keep pace with our adversaries, limit essential information sharing between CISA and the public, and stall efforts to grow the cybersecurity talent pipeline. In addition, such reductions would limit our collective ability to detect and coordinate responses to major cyber vulnerabilities and breaches before they have devastating impacts on the US economy or critical services that Americans rely on, such as clean drinking water, electricity, or the internet.

Historically, Congress has always prioritized investments in our military and in protecting the physical security of our nation. Our cybersecurity readiness deserves the same commitment.

Cybersecurity has historically maintained strong bipartisan support. We respectfully request that the House and Senate Appropriations Committees continue to prioritize robust cybersecurity funding to ensure CISA has the resources and capabilities to meet the cyber threats of today while securing against those of tomorrow.
