Firetools is a GUI application for Firejail security sandbox. It offers a system tray launcher for sandboxed apps, sandbox editing, management, and statistics. The software package also includes a sandbox configuration wizard, firejail-ui.
Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table. Firejail can work in a SELinux or AppArmor environment, and it is integrated with Linux Control Groups.
