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.

Reliable patch management, high uptime, and incredible knowledge base
In terms of security, it does a lot of things that most people still turn off. SELinux is turned on by default. They have pretty good firewall rules in their defaults. The audit rules always take tweaking, but, overall, it comes out of the box not too bad. I used to write scripts to harden them from there. There are multiple ways to provision and patch. You have everything from local repositories to doing it by hand. Their knowledge base is incredible. There is so much information out there. It has never taken me longer than 30 minutes to find an answer to anything, even very tough ones. One company I worked for was a security company, and we did a lot of patching on everything. It was designed around security and email hosting, and uptime was pretty much whatever we wanted it to be. I have had a couple of times when the uptime was bad, but it was caused by a third-party solution. In fact, the Norton antivirus was definitely the worst. Red Hat had nothing to do with it.

Quotes from Members

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

Pros

"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"The solution's stability is very good."
"We use the product for open-source intelligence and identifying vulnerabilities."
"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 interface is good and straightforward to use."
"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."
"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."
"With regard to security, most companies are moving towards the black box approach and Red Hat. It's much more secure compared to the other vendors."
"The product is optimized for resource utilization."
"Red Hat Enterprise Linux is the underlying licensing system that our third-party tool uses. It offers convenience. We can open a case when we want to escalate anything."
"The security features are the most valuable."
"Customer support is valuable."
"The solution has features that simplify adoption for non-Linux users. There is an interface that you can activate on RHEL systems, and on other Linux systems as well, so that you will get a graphical user interface instead of just a shell. It's easier for an administrator who is used to only working on Windows."
"The solution's technical support is really good and responsive. I rate the technical support a ten out of ten."
"It has improved our organization. It has standardized processes."
 

Cons

"The product should improve its security features."
"The product should integrate AI and GPT capabilities."
"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"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, it should be made possible for users to learn about the product easily."
"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 only issue for us was the cost. RHEL is expensive."
"The documentation is an area of concern where improvements are required."
"Its user interface could be better for people who want to use the GUI. They can provide a better user interface with more features."
"I encountered an issue updating the time zone for one of my assigned countries due to a daylight-saving time change."
"I feel like it is going all over the place now. Sometimes it is hard to figure out what is going on. I would like more guidance."
"I really think that the upgrade policies between the major versions, like from from RHEL 5 to RHEL 6, should be much easier, similar to what is in place for upgrading from RHEL 6 to RHEL 6.8."
"Servers: More applications for monitoring (e.g., nmon)."
"Overall, I am happy with it, but I believe, security-wise, it could be better."
 

Pricing and Cost Advice

"The price is good because Kali Linux already provides a good bundle of tools."
"I use it free of charge."
"The tool is open-source."
"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."
"I have used the free version."
"It is an open-source tool."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"The licensing fee is expensive compared to other products."
"RHEL's price seems to be consistently changing, depending on what you're after. We might need a more extended license to lock in a price if it keeps changing. It would be nicer if it stayed steady within a specific range, but it's negotiable. We try to negotiate, and maybe a more extended contract would be better."
"We purchased the Red Hat Enterprise Linux license via Azure and the vendor."
"We are an educational institution and as such, what we pay is less than the average company."
"They knew we would buy tons of Red Hat Enterprise Linux, so they were a little bit more relaxed. We wanted a thousand licenses, and we could pick those up. We true up. Our license experience has been positive with the exception of having to deal with all of the broken-up accounts, which is as much our fault as anybody's."
"For the basic operating system, its price is fair. It is not cheap, and it is also not expensive. For the OpenShift or OpenStack implementation, the cost is a little higher than what I would expect, but it is doable. For a storage solution, it is almost impossible to pay. In comparison to open-source competitors, RHEL has the most cost-effective open-source subscription model."
"The tool is getting expensive."
"We purchased our license from ITM, our local provider."
"This is not a cheap solution but it gets you the support if you ever need it."
