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 solution's stability is very good."
"The solution's most valuable feature is that it is very easy to use."
"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."
"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"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 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 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."
"The product is optimized for resource utilization."
"Technical support is excellent."
"I have seen a return on investment, especially considering the time taken to resolve the problem where we bought some support from Red Hat."
"The most valuable feature of Red Hat Enterprise Linux is its comprehensive ecosystem."
"In Red Hat Enterprise Linux, I am a big fan of the command line."
"The technical support is very helpful."
"It is a very stable operating system. We are not afraid to upgrade it."
"The most valuable feature of Red Hat Enterprise Linux is its support."
 

Cons

"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 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, 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."
"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"
"The product should integrate AI and GPT capabilities."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"The numerous links to different pages disrupt the flow of information and make it difficult to maintain focus."
"Red Hat Enterprise Linux should be available in a free version that developers could try on their own machines before deciding to implement the enterprise edition. It would be nice to have a community version available with all the features so developers can become more familiar with RHEL."
"Sometimes, the platform would be very slow, making it difficult to open labs."
"Red Hat Enterprise Linux's documentation could be improved."
"There are a lot of file systems that are supported by other Linux distributions. Red Hat Enterprise Linux is a little behind those. For example, Btrfs is a file system that is not supported by Red Hat."
"There are performance issues with the response time when accessing the console, but I'm unsure if that's RHEL's fault or if it's due to the lack of CPU or memory on our machines. The enterprise interface could be improved. I can only use the keyboard to transfer files from one system to another. I want to use my mouse on the interface, not just scroll up and down. I would also like my logs archived as an RAR and sent to me."
"To improve standardization, deprecate YUM and transition to DNF."
"The implementation and limitations of SELinux should be re-evaluated."
 

Pricing and Cost Advice

"Kali Linux is a free product, and you don't have to pay for a license."
"I have used the free version."
"The price is good because Kali Linux already provides a good bundle of tools."
"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."
"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."
"Kali Linux is open source."
"The licensing fee is expensive compared to other products."
"The licensing for Red Hat Enterprise Linux in Peru is very expensive."
"Red Hat Enterprise Linux offers a compelling value proposition for corporations due to its robust support infrastructure, which is essential for maintaining enterprise-level systems."
"The licensing is tricky to understand. Enterprises want to be beyond reproach when it comes to licensing. We would rather over-license than under-license. However, that can be complicated with a high-performance development team who may need multiple operating system instances or want to experiment with spinning up many machines to see if something works or sticks."
"I do not know the overall cost, but I know that Red Hat is cheaper than Windows."
"We are a huge VMware shop. Our licensing cost works well with Red Hat. We license based on the data center. The way our license works is that we can run as many Red Hat VMs as we want and pay for a single license. On the VMware side, we gain a lot, and it makes much more sense."
"I find the cost of this solution expensive."
"The price for Red Hat Enterprise Linux is reasonable."
"The solution is moving away from its open source roots and licensing is a little bit of an issue."
