Technology companies on the Internet as inserted security agents

This works proposes an initial reflection on massive leaks of personal data as a threat to civil rights and constitutional guarantees and on the responsibility of technology companies on the Internet, social networks or search engines, in several of those massive leaks. The article analyses the legal regulation of the activity of such companies and highlights the legal duties of tech companies which are closely related to protection of fundamental rights and cooperation with state authorities. The underlying theory is that technology companies hold an institutional position. As intermediaries between state power and citizenship, they have a relevant role in security achievements and in the defense of constitutional rights.
