CISA's Executive Assistant Director for Cybersecurity, Nick Andersen, has called on Congress to urgently renew the 2015 Cybersecurity Information Sharing Act (CISA 2015) before it expires at the end of September. The law, which incentivizes private sector threat intelligence sharing with the federal government, is at risk of lapsing due to legislative delays. While the House and Senate have advanced differing reauthorization bills, time is running short to ensure continuity of the program.

The expiration of the Cybersecurity Information Sharing Act of 2015 (CISA 2015) on September 30, 2025, ended a decade-long legal framework that enabled safe and consistent sharing of cyber-threat intelligence between the U.S. government and private sector. The lapse has led to a significant reduction in the volume and speed of threat data exchanged, with industry groups and federal agencies reporting over a 70% decline in shared indicators of compromise and delays in alert dissemination. Key sectors such as healthcare, energy, and finance have experienced increased risks, including a rise in ransomware activity and slower responses to nation-state threats, as organizations hesitate to share information without the law’s liability protections. In response to the growing concerns, legislation to end the federal government shutdown includes a provision to temporarily extend CISA 2015 through January 30, 2026. The Senate has advanced this bill, which, if passed by the House and signed by the President, would restore the legal protections for information sharing, at least temporarily. Industry groups and cyber experts emphasize the urgent need for a more permanent solution, as the current extension is only a stopgap measure. Lawmakers are considering different approaches to amending and extending the law, with the Trump administration advocating for a 10-year extension without changes, while others propose significant reforms.

The United States faces the simultaneous risk of a federal government shutdown and the expiration of the 2015 Cybersecurity Information Sharing Act (CISA), a law considered vital for public-private cyber threat intelligence exchange. The CISA Act of 2015, distinct from the agency of the same name, is set to lapse at 12:01 am ET on October 1 unless Congress passes a continuing resolution to extend federal funding and the law itself. The House of Representatives previously passed a resolution that would have extended CISA and other bills until November 21, but the Senate rejected it, leaving the law’s future uncertain. The CISA law enables companies to share cyber threat indicators with the federal government, provided they remove personal information not directly related to the threat, and grants legal immunity to those who participate. Supporters argue that this pipeline of information is critical for national cyber defense, while detractors raise privacy concerns. Law firms are advising clients to prepare for the possibility that the law will lapse, though the precise impact on information sharing remains unclear. The looming shutdown has heightened anxiety among federal cyber defenders, as the expiration of CISA could disrupt established channels for sharing threat intelligence between the government and private sector. Historically, national security staff, including cyber personnel, have continued working during funding lapses, but contingency plans suggest that only about a third of the Cybersecurity and Infrastructure Security Agency’s staff would remain during a shutdown. The White House has removed public contingency documents, making it difficult to assess the full impact on the Department of Homeland Security and its cyber components. CISA has already experienced significant workforce reductions, and further cuts could undermine its ability to monitor threats, respond to incidents, and conduct security assessments. The deadlock in funding negotiations, exacerbated by the cancellation of meetings between the White House and Congressional leaders, has left the fate of both the government’s operations and the CISA law in jeopardy. The uncertainty has prompted concern across the cybersecurity community, as the loss of the legal framework for information sharing could hinder the nation’s ability to respond to evolving cyber threats. The situation underscores the interconnectedness of legislative action, government funding, and national cybersecurity posture. If the law is allowed to expire, companies may become more reluctant to share threat data, potentially reducing the government’s visibility into emerging threats. The outcome of the ongoing political negotiations will have significant implications for both public and private sector cybersecurity operations in the United States.
