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 2015 Cybersecurity Information Sharing Act is at risk of expiring at the end of September 2025 due to legislative gridlock. Multiple attempts at both short- and long-term extensions have failed, raising concerns about the future of legal protections for cyber threat information sharing. Industry and government warn that a lapse could significantly hinder public-private cyber defense collaboration.

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.

U.S. senators are pushing for a 10-year extension of the Cybersecurity Information Sharing Act of 2015 (CISA 2015), which was temporarily extended after the recent government shutdown but is set to expire at the end of January. Lawmakers argue that allowing the law to lapse would hinder the ability of companies and government agencies to share cyber threat data without legal risk, potentially undermining national cybersecurity efforts. Senators Mike Rounds and Gary Peters, who are sponsoring the reauthorization bill, emphasize that the law is crucial for enabling collaborative vulnerability hunting and patching, especially during 'hunt forward' missions conducted by U.S. Cyber Command. The proposed extension would maintain the law's current provisions, with only a name change, and is supported by the administration. However, the path to permanent reauthorization remains uncertain, raising concerns about the continuity of legal protections for cyber threat information sharing.
