Qubes Os

Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes. These qubes, which are implemented as virtual machines (VMs), have specific:

  • Purposes: with a predefined set of one or many isolated applications, for personal or professional projects, to manage the network stack, the firewall, or to fulfill other user-defined purposes.
  • Natures: full-fledged or stripped-down virtual machines based on popular operating systems, such as Fedora, Debian, and Windows.
  • Levels of trust: from complete to non-existent. All windows are displayed in a unified desktop environment with unforgeable colored window borders so that different security levels are easily identifiable.

Qubes eliminates this concern by allowing us to divide a device into many compartments, much as we divide a physical building into many rooms. Better yet, it allows us to create new compartments whenever we need them, and it gives us sophisticated tools for securely managing our activities and data across these compartments.

It is a portable operating system that protects against surveillance and censorship. Tails includes a selection of applications to work on sensitive documents and communicate securely. All the applications are ready-to-use and are configured with safe defaults to prevent mistakes.

Tails includes:

  • Tor Browser with uBlock, a secure browser and an ad-blocker
  • Thunderbird, for encrypted emails
  • KeePassXC, to create and store strong passwords
  • LibreOffice, an office suite
  • OnionShare, to share files over Tor

To prevent mistakes:

  • Applications are blocked automatically if they try to connect to the Internet without Tor.
  • Everything in the Persistent Storage is encrypted automatically.
  • Tails does not write anything to the hard disk. All the memory is deleted when shutting down.

Everything you do on the Internet from Tails goes through the Tor network. Tor encrypts and anonymizes your connection by passing it through 3 relays. Relays are servers operated by different people and organizations around the world. Learn more about Tails

Discreet Linux

It is an operating system with the special purpose of protecting data (more precisely: people) against surveillance attacks with trojan software. It is  designed for ease of use by people without deeper computer knowledge but high security requirements. It creates a secure, isolated environment for processing and encrypting/decrypting sensitive data.

Even strong end-to-end encryption becomes worthless if the attacker can control the systems that perform the encryption. Discreete Linux brings the endpoints of encrypted communication out of reach of trojan attacks.
