After a prolonged debate and months-long consideration of amendments, on Tuesday the Senate passed S. 754, which includes the Cybersecurity Information Sharing Act (“CISA”) of 2015, by a vote of 74-21. CISA has the support of the White House and many industry stakeholders, but some of the most well-recognized privacy advocacy organizations oppose it. The House of Representatives must now decide whether to pass CISA or work with the Senate on compromise legislation that incorporates the House cybersecurity information sharing bills, H.R. 1560 and H.R. 1731. It remains to be seen what form the final cybersecurity information sharing bill will take, but the Senate’s overwhelming vote for CISA suggests that the chances for overall passage are stronger than ever.
