Subgraph OS security and anonymous browsing

Subgraph OS is a Debian-based Linux distribution and offers security services anonymous web browsing with hardening features.

Subgraph OS uses a hardened Linux kernel, and a firewall application that helps you specifically block executables from network access. Distribution causes all Internet traffic you use to pass through the Tor network. Subgraph OS

The file manager of the distribution has tools to remove the metadata that leaves the files and is integrated with the OnionShare file sharing application. The e-mail client icedove works automatically with Enigmail to encrypt your emails.

Most of the Subgraph OS code was written with Golang, which is a secure language for memory. Golang libraries are also written in pure Golang, unlike other popular languages ​​like Python. While Python's runtime can be secure in memory, the C languages ​​commonly used by libraries expose Python-written tools to old memory corruption vulnerabilities.

One of the best security features of the distribution is that it uses Sandboxed applications in addition to the above.

So fragile or Internet-exposed applications work in sandbox environments. The sandbox framework, called Oz, is designed to isolate applications from the rest of the system. Access to system resources is only granted to applications in need. For example, PDF viewer and image viewer can not access any network interface from the sandbox.

Sandboxed applications are:

Web Browser
Email client with built-in support for encryption
CoyIM instant messenger
LibreOffice productivity suite
PDF viewer
Image viewer
Video player

Let's say that distribution offers several interesting features, but it's new. New distribution means we do not know what kind of support it offers, or whether it will continue to exist after 1 with 2 years.
