Firejail vs Tenki Sandbox

Firejail is a free, self-hosted Linux sandboxing program for restricting untrusted applications, servers, graphical programs, and login sessions. It uses Linux namespaces and seccomp-bpf so sandboxed processes receive private views of network, process, and mount tables. The software runs on Linux computers with a 3.x kernel or newer. Security controls include protocol filtering, noroot user namespaces, Linux capabilities, D-BUS filtering, and optional AppArmor or SELinux support. Mandatory Access Control can block more than 1,000 desktop applications from passwords, encryption keys, and private data, with more than 1,000 profiles available in /etc/firejail. Firejail can create an isolated TCP/IP stack with routing, firewall, and interfaces, and nettrace can inspect traffic. AppImage packages are supported. Firetools adds a Qt5 graphical launcher, tray integration, editing, management, and statistics; FDNS provides DNS-over-HTTPS through non-logging providers. Running sudo firecfg integrates application menus and file-manager launches. The project targets home users and Linux beginners rather than enterprise customers.
