firejail - 0.9.64.4-2+deb11u1 main

Firejail is a SUID security sandbox program that reduces the risk of
security breaches by restricting the running environment of untrusted
applications using Linux namespaces and seccomp-bpf. 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.
