Ciyagi Ciyagi - PeerSpot reviewer
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
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.
Salim Ahmed - PeerSpot reviewer
System Administrator at mmcytech
Has supported secure application hosting and reliable server management
I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.
