Overview

• The House Homeland Security Committee unanimously approved the Wimwig Act to replace and modernize CISA 2015, sending the measure to the full House with bipartisan backing.
• CISA 2015 is set to sunset on September 30, and experts caution a lapse could slow federal advisories, deter industry collaboration, and strain cooperation with allied cyber agencies.
• Banking trade groups urged swift action, arguing that the loss of liability and antitrust protections would reduce timely intelligence exchange and expose firms to greater legal risk.
• A DHS inspector general report found participation in the Automated Indicator Sharing program fell from 304 entities in 2020 to 135 in 2022, with a 93% drop in shared indicators after a key agency halted contributions.
• While the House bill includes updates such as clarified liability provisions, AI-era definitions, outreach requirements, and voluntary technical assistance, the Senate is weighing a clean 10-year extension to avoid any gap in authority.
