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.

Cons

"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."
