Cyberspace Administration of China - Definition from the Hotspot Shield Glossary
The CAC is the main overseeing organization for China that is responsible for the censorship and control of the internet for the whole nation. The organization was founded in 2014 and answers directly to the Central Leading Group for Internet Security and Informatization.
The CAC regulates many areas of the Chinese internet including the choice of usernames, the remarks and comments made online and how appropriate they are, the implementation and use of VPN networks and the content of internet portals. Aside from regulating tasks, the CAC is also heavily involved in the review of network products and their procurement when concerned with national security. The Chinese public has generally negative views on the CAC and regard it as a blight against their online freedom.
