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

"You can work with the UI or in command line, if you prefer."
"The user access level is most valuable. When you do administration with CentOS, the number of customizations that you can do for each user is higher than other solutions. It is very customizable."
"It is a scalable and cost-effective product compared to public cloud solutions."
"The solution is open source."
"The solution is easy to troubleshoot."
"CentOS is very easy to use, and all the commands are user-friendly."
"The most valuable feature of CentOS is that it is easy to use."
"CentOS' best feature is that it's the standard product for Linux, so it's well-supported."
"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."
"The solution's stability is very good."
"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"Additionally, it now includes comprehensive migration analytics and reporting capabilities."
"The most effective features of Kali Linux include its stability as a Linux operating system, its flexibility in configuring resources such as partitions, its powerful and stable file system, and its multi-user capability, which allows for setting user privileges and rights. Additionally, Kali Linux provides access to a wide range of free and open-source applications for testing and development purposes."
"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

"The solution is stable, however, it could always be even more stable if possible."
"This solution is no longer supported and will not receive any updates going forward."
"The solution must improve its security."
"The interface could be improved."
"The server system is a little bit tough to manage."
"CentOS could improve by having troubleshooting logs."
"Previous versions were unstable."
"CentOS can be somewhat difficult for beginners, as it has a complex UI, especially for those not in the IT field."
"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."
"The tool is slightly difficult to learn."
"The product should improve its security features."
"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."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
"There can be some lagging issues because the product gets stuck at times, making it an area of concern where improvements are required."
"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."
 

Pricing and Cost Advice

"For the enterprise version of CentOS, there is a license required. However, for personal use, I do not need a license."
"The solution is open source."
"The solution is open source so is free."
"We use the free, open-source solution because we cannot afford the price for Linux."
"We are using a subscription-based license option for CentOS."
"CentOS is an open-source tool."
"There are no licensing fees. CentOS is a free solution."
"It is open-source, which means it is a free product. It has a one-time deployment cost."
"The licensing fee is expensive compared to other products."
"Kali Linux offers a perpetual license, meaning you pay for it once and can use it. While free versions of Linux are available, Kali Linux, being an enterprise edition, usually comes with a perpetual license. I rate its pricing a five out of ten."
"The tool is open-source."
"I use it free of charge."
"Kali Linux is a free product, and you don't have to pay for a license."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"It is an open-source tool."
"The price is good because Kali Linux already provides a good bundle of tools."
