The Cybersecurity Information Sharing Act of 2015 (“CISA 2015”), which provides protections for sharing cybersecurity threat information with the federal government and others, was reauthorized under the funding bill to reopen the federal government, which was enacted on November 12, 2025.  The information sharing mechanisms and protections under CISA 2015, which had previously sunset on September 30, 2025, will now extend through January 30, 2026.
