Tresorit is an end-to-end encrypted file sharing service aimed at sharing files among team members. Tresorit has supported Windows, OS X, iOS, Android, and even Blackberry and Windows Phone while now they are finally supporting the Linux desktop.
Tresorit has released a native Linux binary for customers wishing to engage in an encrypted file-sharing workflow from their desktop. Ubuntu, Debian, Arch, Fedora, Gentoo, Mint, SUSE, and CentOS are all mentioned as being supported.
Chances are if you've ever dealt with Pandora music streaming from the Linux desktop you've encountered Pithos as the main open-source solution that works out quite well. Released today was Pithos 1.2 and it ships with numerous enhancements for this GPLv3-licensed Pandora desktop client.
Pithos 1.2 adds a number of new keyboard shortcuts for the main window, initial support for translations, an explicit content filter option, reduced CPU usage with Ubuntu's default theme, redesigned dialogs and other UI elements, and more.
The latest major release is out of OPNsense, a BSD open-source firewall OS project derived from pfSense and m0n0wall.
OPNsense 16.7 brings NetFlow-based reporting and export, trafic shaping support, two-factor authentication, HTTPS and ICAP support in the proxy server, and UEFI boot and installation modes.
