Subgraph is a Linux-based operating system designed to be resistant to surveillance and interference by sophisticated adversaries over the Internet.
Subgraph OS is designed to be difficult to attack. This is accomplished through system hardening and a proactive, ongoing focus on security and attack resistance. Subgraph OS also places emphasis on the integrity of installable software packages. It features grsecurity/PaX, Linux namespaces and xpra for application containment, mandatory file system encryption, and resistance to cold boot attacks and ensures each application goes through a different circuit over the Tor network.
