Tomb is a free and open source tool for folder encryption on GNU/Linux, creating encrypted storage folders opened and closed with associated key files protected by a user-chosen password. It uses dm-crypt and LUKS via cryptsetup and is a shell script. Tomb works only on GNU/Linux systems and WSL2 starting with Windows11.
A guide that explains how to harden Linux for security and privacy, covering distributions, kernel hardening, mandatory access control, sandboxing, root account restrictions, firewalls and identifiers. It states that Linux is not a secure operating system and that the guide is distribution-agnostic and focused purely on security and privacy.
Lockdown Privacy offers a firewall and a Secure Tunnel VPN for blocking trackers, ads and badware in apps. The firewall is described as open source and on-device. The site states the products are Openly Operated and provide transparency into data handling. The listing covers iPhone, iPad and Mac.
Firejail is a SUID program for Linux that restricts the running environment of untrusted applications using Linux namespaces and seccomp-bpf. Written in C with almost no dependencies, it runs on Linux computers with a 3.x kernel or newer. It includes security profiles for many Linux programs, and commands can be prefixed with "firejail" to start a sandbox.
KextViewr is a macOS utility that displays all currently loaded kernel modules (kexts), showing information such as collection, size, address and architecture. It offers a UI alternative to Apple's kmutil with filter, search and JSON export capabilities, and requires the com.apple.private.kernel.get-kext-info entitlement. Supported on macOS 11 and later.
MailTrackerBlocker is an extension and plugin for Apple Mail on macOS that blocks email trackers, read receipts and spy pixels. It labels who is tracking you and strips spy pixels from HTML before display, so disabling remote content loading is unnecessary and images can be shown. Supported on macOS 14.3+ as an extension and macOS 10.11-13.x as a plugin.
SuspiciousPackage is a Linux, macOS, BSD, or Unix resource for tools, documentation, communities, or system workflows.
