SQLmap for web application testing and good for web application penetration testing, network testing, vulnerability assessment of any devices or domains
Sometimes, I do face challenges. There's an issue where sometimes during the initial installation, it doesn't install properly. It gives multiple errors like packages not installing, so we have to install those tools separately. For instance, if we want to install a network or other tools, we have to install those complete toolkits manually. So, the challenge is with the initial setup, where I sometimes get errors. Regarding wireless attacks, OS attacks, and social engineering... the tools should be easier to learn because I know everything very well, but some people in my team struggle to understand. If there were GUI interfaces for the tools, it would help me guide my team in using them step-by-step. Command lines are very difficult for other team members who know the tool's purpose but not the Linux commands. GUI interfaces need more improvement. So, the UI interface needs improvement to make it more visible and easier for users. Expert users can do everything without any issues, but new users will struggle.

Performs efficiently but requires overcoming a learning curve
There are many differences between Ubuntu Linux and Windows as they are totally different systems. You need to have more knowledge about Linux before using Ubuntu Linux. Although it is designed as a desktop system, basic knowledge is still required. Windows can be used by any layman, which is the main difference. I do not know much about security breaches or potential issues. The Wi-Fi and wireless capabilities work perfectly fine. Excluding the learning curve, I would rate it a 10. However, considering the learning curve, I would give it a six or seven. My advice would be to have patience. Overall rating: 10 out of 10.

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."
"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."
"The solution's most valuable feature is that it is very easy to use."
"Additionally, it now includes comprehensive migration analytics and reporting capabilities."
"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 most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"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."
"I found using this solution pleasurable to learn since it is something different than Windows."
"The most valuable feature of this solution is that Linux has cost-effective licenses."
"The feature that I have found the most valuable is that it is open source. It is also very easy to manage. We can manage it ourselves."
"There are many features I like about this solution, but one that stands out, is that it allows me to easily install new packages and to have recent packages available."
"It keeps you secure from virus and malware attacks."
"Ubuntu Linux is the most secure option on the market."
"I like the flexibility."
"The most valuable features are the pseudo-terminal and it is the most open-sourced operating system that can be used."
 

Cons

"The tool is slightly difficult to learn."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
"The product should improve its security features."
"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."
"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."
"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 some drivers that are not there encoded, however, I thought that was pretty normal. They could be more comprehensive."
"The biggest improvement, which is also applicable to Linux in general, with Ubuntu Linux is getting things standardized as to where you're going to put your configuration files and how they're going to work. Package names also need to be improved so that the package name doesn't have any match with configuration file systems and things like that. Ubuntu is still better than some of the others, such as Red Hat Linux or CentOS."
"The solution could improve its GUI personalization."
"The solution has a bit of a learning curve. It's not too high, however, you do need to understand the solution to deploy it and work with it effectively."
"The solution could be better integrated with Microsoft."
"You need a lot of bandwidth during the initial setup in order to pull from the repository. Without good bandwidth, you'll get cut off and the implementation will fail."
"Lack of integration with other operating systems."
"The migration part when migrating an application or one version of Ubuntu Linux to another is quite hectic. During the process, one or many applications might crash."
