In-depth documentation available and command-line utility works well
One issue I recently faced, but I think it was due to my IT support guys, was that when the server storage gets full, the service crashes. It's very difficult to regain access and stability in that situation. That could be improved. So, the stability might be improved. But I don't think it's a CentOS-level issue. The system administrators need to come up with a solution for that, but I don't think it's CentOS's fault. I haven't done any research [R&D] on this issue. There's one thing for sure. We recently migrated from CentOS 7 to CentOS 9, and it was a bit difficult. For example, updating Windows is simple; you just download it, and it takes about 15-20 minutes. But that's not the case with migrating from CentOS 7 to 9. We had to back up the entire server, launch a new server, and then restore the backup to the new server. We couldn't directly migrate. I think that was a bit of a problem. The setup and updates are not that new in CentOS.

Has small footprint and low maintenance cycles
Pre-installed tools can provide basic training and security measures, which is helpful. However, these tools may not be sufficient to secure your workload fully. That's why it's important to complement them with other specialized security tools to enhance your overall security. Before using Kali Linux, make sure you know its pros and cons. It's a good system to learn because it's the best choice for some situations. It has default firewall settings that block everything by default. It's up to the user to decide how much they want to open up. Learning Kali Linux takes time because it relies on command-line tasks instead of graphical interfaces. Practice is key to becoming comfortable with it.

"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"We use the product for open-source intelligence and identifying vulnerabilities."
"I use the tool with Nmap to perform network audits. We use it to find vulnerabilities in our network through attacks. It's for those who want to launch or create viruses or perform attacks on systems. With Kali Linux, you can conduct penetration testing for networks, web applications, and Android mobile apps."
"In general, Kali Linux is used for hosting applications, developing new applications, and operating systems. It's also used in containers and nodes. The tool offers a smaller footprint than Windows because it lacks the functionality of graphical user interfaces. One advantage of Kali Linux is its lower maintenance requirements than Windows, with slower update cycles and easier maintenance procedures."
"The interface is good and straightforward to use."
"The solution's most valuable feature is that it is very easy to use."
 

Cons

"We occasionally have issues with software installation."
"There could be more integration features included in the product."
"It is challenging to scale the solution when we have to increase the storage capacity from one end."
"CentOS could be improved by being more secure. Of course, we use a firewall, but security is always a concern."
"Previous versions were unstable."
"The product lacks a graphical user interface that can help users automate certain systems using the native features offered by CentOS."
"The tool has no official support."
"This solution is no longer suited to our business following the change they have made to the release process. It is no longer an enterprise solution."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"From an improvement perspective, Kali Linux could include more ML to help with academic literature, as it is one of the areas where there are shortcomings in the solution."

"I would like for them to offer more features for the free version in order for users to test them in their internal environment before purchasing."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"Unfortunately, my current tool runs on Windows 10, and its use is restricted to enterprise versions. Integrating this tool or similar functionalities into Kali Linux for non-enterprise users would be incredibly valuable."
"The tool is slightly difficult to learn."
"The tool is already stable and well-developed, so there's minimal feedback for enhancement or change. However, it should improve security, which is crucial, especially with the increasing use of Kali Linux in cloud environments."
