Expiry of CISA 2015 Leaves US Intelligence Sharing Exposed
🔒 The 2015 Cybersecurity Information Sharing Act (CISA 2015) has expired after lawmakers failed to extend legal safe-harbors for voluntary threat sharing via the Automated Indicator Sharing program (AIS). Amid a congressional funding standoff and a resulting partial government shutdown, industry leaders warn the lapse exposes companies to litigation and may deter intelligence exchange. Security executives say reduced sharing could create blind spots, elevate software supply-chain risk and slow development of AI-driven defenses.
