CISA 2015 is a cybersecurity law that facilitates the sharing of threat intelligence between government and businesses without imposing additional regulations. It has become a crucial component of America's cyber defense, helping to prevent numerous cyber attacks over the past decade by enabling rapid communication of threat warnings.

If CISA 2015 expires, small and medium-sized businesses (SMBs) could face increased vulnerability to cyber attacks, particularly ransomware. Recent data indicates that ransomware costs SMBs an average of $432,000 per attack, and many cannot survive extended operational disruptions. The expiration would weaken the early warning system that helps these businesses stay ahead of emerging threats.

CISA 2015 is vital for small and medium-sized businesses because it provides liability protections that encourage information sharing about cyber threats. With SMBs representing 98% of cyber insurance claims and accounting for significant economic contributions, the loss of these protections could lead to devastating impacts on their operations and the broader economy.
