Subgraph OS

SubgraphOS is a desktop operating system that is designed to be both usable for non-technical users and secure against active interference and targeted attacks. It is specifically designed to protect users at risk of identification and surveillance by determined, capable, network-borne adversaries meaning there is no physical access to the user or hardware. SubgraphOS prioritizes privacy through integration of Tor, including a default setting that restricts communication applications to only send data through the Tor network. The OS also includes a more secure instant messaging and email client that is configured by default for PGP and Tor support. Just as important to the security features, SubgraphOS emphasizes the user experience by considering usability during the development cycle.
