Provides valuable real-time data scanning for vulnerability assessment

We don't know if Kali Linux has the port scanning capability yet, but that is an area of improvement because we are working with DMZ zones and customized ports. If we can add featured customized port scanning and DMZ zone capability, then it will be a very great tool. It might be there, but we are not exploring it yet. We are not exploring 100% of Kali Linux capabilities. If real-time customized port scanning can be added, for example, instead of a default port such as 8080 or 443, if we can use a customized port such as 9876, that capability would be great. The only point that I didn't find on Kali Linux for now is the ability to customize port scanning.

Has supported seamless migrations and enabled running complex data workloads securely

The best features Rocky Linux offers include clustering and all the packages from Red Hat.Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux. Everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe. Rocky Linux is very good for security and other aspects. Since migrating to Rocky Linux, I've seen specific outcomes such as improved security because CentOS stopped the project, and security patches aren't being released. We need to maintain a system similar to Red Hat, which is very stable and has many features such as file system, topology, and containers.

Quotes from Members

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

Pros

"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."

"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."

"The outcomes from using Kali Linux in our organization are significant; we experienced reduced cybersecurity attacks and improved application security, leading to decreased attack surfaces and quicker testing cycles that enabled faster launches and installations."

"The solution's stability is very good."

"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."

More Kali Linux pros

"It helps us keep our workstations in sync and ensures consistent settings across most of our machines."

"Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux, everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe."

More Rocky Linux pros

Cons

"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 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 product should improve its security features."

"Many users utilize Kali Linux through virtual machines. Sometimes Kali Linux has issues detecting hardware such as inbuilt or external Wi-Fi adapters."

"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."

"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."

"There are areas for improvement in Kali Linux, particularly regarding its use of the Linux kernel, which requires external additional patching, and the fact that network services are disabled by default, which complicates usage; enhancing user-friendliness through more GUI-based tools and better integration could be beneficial."

More Kali Linux cons

"I have certain problems with the tool's DNS part, making it an area where improvements are required."

"One of the potential issues is that if you don't pay for support, you may need to manage certain aspects on your own and rely on the community for assistance."

"Rocky Linux could be improved by having more integration with Kubernetes."

"I see some performance-related issues, but we are still checking on that, and we don't know if it is related to the OS or the resource; that is something still to be checked from our end."

"In terms of improvement, Rocky Linux needs to clarify its identity and target audience."

"The solution's audio integration for virtual machines could be improved."

"Improved integration with Windows, particularly Active Directory, would be beneficial for the product. Currently, this aspect requires additional effort."

"The package versions can be quite older compared to other distributions such as Ubuntu."

Pricing and Cost Advice

"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."

"The price is good because Kali Linux already provides a good bundle of tools."

"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."

"I use it free of charge."

"Kali Linux is open source."

"The tool is open-source."
