What makes Firejail so special it qualifies for inclusion in our Essential System Tools feature? Above all, it puts users first.
It’s really easy to install and use. More time to spend actually using software. Most people won’t need any custom configuration. There’s a wide range of software which come with sandbox profiles.
The software helps to reduce the risk of security breaches. It’s lightweight and while it uses CPU cycles, the overhead is remarkably low. Firejail sandboxes do not each run their own copy of a full-blown operating system. Instead they operate in a resource-isolated environment created by standard facilities of your system’s existing Linux kernel. As such, despite the high level of protection offered, the overhead of running a Firejail sandbox is extremely low. So your software, including games, run at full steam, unlike a full virtualisation environment.
Firejail is an excellent tool for the security conscious. While it adds a layer of protection, you should use it with other security tools. We use it mainly for web browsing, and to lock down services.
