Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.

Provides BTRFS file system, which allows you to take snapshots
I only use the tool for testing purposes on my team, but multiple people use it. We don't make a team effort to install the solution. When it comes to maintenance, we ask our company to buy SUSE Linux Enterprise. My team consists of 13 people. We are currently integrating the solution with Ansible to do some coding. Although not a full-fledged automation, we are integrating the solution with Ansible and executing a couple of playbooks connected to openSUSE Leap. I would recommend the solution to other users looking for an open-source solution. Overall, I rate the solution a nine out of ten.
