CISA 2015 expiry threatens private sector threat sharing
Failing to renew CISA 2015 could silence threat sharing between companies, undermining collective cyber defence across critical infrastructure sectors.
Congress has under 90 days to renew the Cybersecurity Information Sharing Act (CISA) of 2015 and avoid a regulatory setback. The law protects companies from liability when they share cyber threat indicators with the government or other firms, fostering collaboration.
Before CISA, companies hesitated due to antitrust and data privacy concerns. CISA removed ambiguity by offering explicit legal protections. Without reauthorisation, fear of lawsuits could silence private sector warnings, slowing responses to significant cyber incidents across critical infrastructure sectors.
Debates over reauthorisation include possible expansions of CISA’s scope. However, many lawmakers and industry groups in the United States now support a simple renewal. Health care, finance, and energy groups say the law is crucial for collective defence and rapid cyber threat mitigation.
Security experts warn that a lapse would reverse years of progress in information sharing, leaving networks more vulnerable to large-scale attacks. With only 35 working days left for Congress before the 30 September deadline, the pressure to act is mounting.
