A vital cyber defense law known as the Cybersecurity Information Sharing Act of 2015 (CISA 2015) is poised to expire at the end of the month, and leaders in the House and Senate are working to negotiate a replacement within the next 26 days. The House Committee on Homeland Security unanimously approved legislation on September 3, 2025 – titled the Widespread Information Management for the Welfare of Infrastructure and Government Act (WIMWIG) – to reauthorize CISA 2015, and Congress is also considering other proposals.
