TAG's research has shown the proliferation of commercial surveillance and the extent to which commercial spyware vendors have developed capabilities that were previously only available to governments with deep pockets and technical expertise. The growth of the spyware industry puts users at risk and makes the Internet less safe, and while surveillance technology may be legal under national or international laws, they are often used in harmful ways to conduct digital espionage against a range of groups. These abuses represent a serious risk to online safety which is why Google and TAG will continue to take action against, and publish research about, the commercial spyware industry.
