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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It’s a simple, straightforward implementation."

"It has minimal updates compared to other distributions."
"CentOS is very easy to use, and all the commands are user-friendly."
"There are a lot of sources on the internet that you can use to solve any issues, and people share their experiences. It's not a closed system"
"The solution is easy to troubleshoot."
"The scalability of CentOS is good. We can deploy the operating system in many hardware, laptops, and servers."
"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."
"The solution's most valuable feature is that it is very easy to use."
"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"Kali Linux is much better than other OS because it gives you a good set of tools. It is preferred for vulnerability assessments and cybersecurity."
"I'm mostly using for the web security web application, so end map and the troubleshoot will it's my price, and it's available in ColliNX."
"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 solution's stability is very good."
 

Cons

"They could build more options into the wizard."
"When comparing the GUI of CentOS to Microsoft Windows or Mac, it could improve."
"The stability could always be improved."
"The security could be improved because the server system isn't very secure."
"Integration with Open Stack could be improved."
"Like every operating system, it could be more secure."
"The solution could improve by making the management tools better for the DevOps teams. For example, WebEX and Webstacks."
"It would be ideal if Red Hat would continue the CentOS versions in an open-source format. They seem to be moving away from that. Now only paid versions are available."
"The product should improve its security features."
"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."
"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."
"There can be some lagging issues because the product gets stuck at times, making it an area of concern where improvements are required."
"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."
"The tool is slightly difficult to learn."
"The product should integrate AI and GPT capabilities."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
