Summary

Ranking member Thanadar and other members urged a multi‑year reauthorization of the Cybersecurity Information Sharing Act of 2015, arguing long‑term authority is needed to sustain sector‑specific intelligence sharing as AI accelerates adversary capabilities; witnesses endorsed stronger sharing channels and ISAC coordination.

Ranking member Thanadar told the panel that CISA 2015 is set to expire and argued Congress should extend the law for a long term (he recommended a 10‑year reauthorization) to preserve privacy and liability protections that encourage private‑sector data sharing about cyber vulnerabilities.

Witnesses including Roy Hansen (Google), Doctor Logan Graham (Anthropic), and others told the subcommittees they support continued and expanded information sharing. Hansen highlighted sector‑specific Information Sharing and Analysis Centers (ISACs) and industry frameworks such as Google’s SAFE as ways to operationalize sharing; Graham and other witnesses emphasized the need for rapid, sensitive channels to share novel indicators of AI‑driven abuse so defenders can mitigate attacks in near real time.

Members and witnesses framed reauthorization as essential to preserve cooperative defenses while balancing privacy and commercial concerns. The hearing did not produce legislation; members asked witnesses for follow‑up briefings and suggested a bipartisan working group to develop concrete legislative recommendations.
