After it was revealed that the U.S. National Security Agency and the FBI secretly scour Internet usage data, several tech companies were asked to respond to questions about whether they participate and hand over information.

Here is what some of the reportedly involved companies had to say:

Apple

"We have never heard of PRISM. We do not provide any government agency with direct access to our servers and any agency requesting customer data must get a court order."

Apple spokesman Steve Dowling told Bloomberg

AOL

"We do not have any knowledge of the Prism program. We do not disclose user information to government agencies without a court order, subpoena or formal legal process, nor do we provide any government agency with access to our servers."

Facebook

"When Facebook is asked for data or information about specific individuals, we carefully scrutinise any such request for compliance with all applicable laws, and provide information only to the extent required by law."

Facebook's chief security officer told The Guardian

Google

"First, we have not joined any program that would give the U.S. government—or any other government—direct access to our servers....Second, we provide user data to governments only in accordance with the law. Our legal team reviews each and every request, and frequently pushes back when requests are overly broad or don’t follow the correct process."

Microsoft

"We provide customer data only when we receive a legally binding order or subpoena to do so, and never on a voluntary basis. In addition we only ever comply with orders for requests about specific accounts or identifiers. If the government has a broader voluntary national security program to gather customer data we don’t participate in it."
