Firejail, alternative Linux à Windows Sandbox
Mis à jour le
Notre avis
Firejail is a solid replacement for Windows Sandbox if you need lightweight, temporary isolation for untrusted applications on Linux. It starts quickly, resets on exit, and enforces strict resource and filesystem restrictions by default. While it doesn't offer the exact same disposable VM experience, it provides strong process and system call isolation using Linux namespaces and seccomp. Best suited for command-line tools, scripts, and GUI apps where full OS virtualization isn't required. Users expecting a clean, one-click throwaway environment similar to Sandbox will find Firejail effective, especially with predefined profiles.

Ce qui fonctionne pareil
- Both isolate untrusted applications to protect the host system
- Enforce temporary environments that reset upon exit
- Support network isolation and restricted resource access
- Start quickly with minimal user setup
- Prevent persistent changes to the main system
Ce qui change
- Firejail is not a full VM — it uses container-like isolation, not hardware virtualization
- No native support for exporting or snapshotting environments
- Less isolation from kernel exploits compared to Sandbox's VM-based approach
- No built-in graphical session reset like Windows Sandbox
- Custom profiles may be needed for non-standard apps

Firejail does not use or support Windows Sandbox configuration files (.vbs, .vhd, or .wsb). It relies on its own profile system written in plain text. There is no direct import mechanism. If you're migrating sandboxing rules or settings, you'll need to recreate them manually in Firejail's profile format. No tools exist to convert Windows Sandbox configurations to Firejail profiles.
Passer de Windows Sandbox à Firejail, étape par étape
- Install Firejail via your package manager (e.g., 'sudo apt install firejail')
- Review available profiles in /etc/firejail/
- Test running an untrusted app with 'firejail --profile=default appname'
- Customize or create a new profile if needed
- Use 'firejail --private' for fully temporary home directories

Installer Firejail sous Linux
sudo apt install firejailsudo apt install firejailsudo dnf install firejailsudo pacman -S firejailsudo zypper install firejailQuestions fréquentes
Does Firejail require virtualization to work?
No, Firejail uses Linux namespaces and seccomp, not virtualization. It runs directly on the host kernel without needing CPU virtualization extensions.
Can I run GUI apps in Firejail like in Windows Sandbox?
Yes, Firejail supports GUI applications through sandboxed X11 or Wayland sessions, though display isolation is not as strict as in a full VM.
Is Firejail as secure as Windows Sandbox?
It depends: Firejail offers strong application-level isolation but not kernel-level separation. For most untrusted apps, it's sufficient, but a VM-based solution is safer against kernel exploits.
