CISPA also protects businesses that share cyberthreat information from lawsuits.
Some tech companies and trade groups, including Verizon Communications and the National Cable and Telecommunications Association, praised the bill. The sharing of cyberthreat information is a "critical missing link in our efforts to detect and deter cyberattacks," Michael Powell, NCTA's president and CEO, wrote in a letter to the sponsors.
But the American Civil Liberties Union and Demand Progress, a digital rights group, both repeated their opposition to CISPA.
"CISPA does not require companies to make reasonable efforts to protect their customers' privacy and then allows the government to use that data for undefined national-security purposes and without any minimization procedures, which have been in effect in other security statutes for decades," the ACLU said in a statement."
