If we had installed it on-premises or through other means, it would have incurred significant money and effort to create the VMs, deploy it on machines, and then delete and format it after use.

Kali Linux is a time-saving and cost-saving solution.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
It has definitely saved time and generated a return on investment as well.

If we compare support from Microsoft, it is not the same because Kali Linux is open source and we are not paying any license cost.
Assistant Consultant at a tech services company with 11-50 employees
The technical support team’s response time is very slow.
Senior Technical Manager at Peristent Systems
We have an internal team that supports all the Microsoft issues within the system.

Room For Improvement

Kali Linux could improve with a user-friendly GUI, enhanced support, better documentation, AI integration, and optimized VM images.
Windows 11 needs better integration, security, performance, and AI features while addressing stability, compatibility, and cost issues.
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.
Senior Technical Manager at a tech vendor with 10,001+ employees
I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
If there were video courses attached to how to safely use it, especially for absolute beginners with no previous experience using Linux operating systems, I think that could be very useful.
Cloud Ops Lead at a tech vendor with 10,001+ employees
For a better experience, Windows 11 should be improved to take fewer resources.
Delivery Manager at Ford Motor Company
The needed improvements in Windows 11 include that the Copilot integration needs a better user interface experience with rich features, alongside making a very simple UI experience as well.

It still feels more oriented toward consumer use rather than enterprise use, and the company is forced to maintain extensive backward compatibility, which creates technical debt.
Software Engineer at a tech services company with 51-200 employees

Featured Reviews

Ciyagi Ciyagi - PeerSpot reviewer
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Naveenkumar Lakshman - PeerSpot reviewer
Presales Engineer at Crayon AS
Daily work has become smoother and organized as I manage calls, notes, and files efficiently
The best features that Windows 11 offers in my opinion are Notepad++ and the integration, as I could use Microsoft 365 on it and I could also run many applications. If I want to use Linux, then I could use Windows Subsystem for Linux as well. Most of the industry-wide applications are easily installable on Windows 11 and user-friendly as well. Windows 11 has definitely impacted my organization positively because you could see that all the day-to-day activities, most of our professionals would use a Windows system itself. In terms of productivity, Windows 11 has made a positive difference as we use a mail inbox with its links and Microsoft Teams, which is available. Windows 11 is natively installable and very friendly with the compatible operating system, and alongside, we have other applications that are available. Edge browser, which is the default browser for Windows 11, is also a good browser and a very decent option. Additionally, we have other features available for the day-to-day activities. You can see it gives you a basic calendar, calculator, and camera options, and you have the File Explorer. You get a pretty decent operating system for a layman to work on a day-to-day basis. While there are certain tasks that consume a certain amount of time, Windows 11 reduces the time. The usability and architecture, how it is built, makes a user get into a state where they don't need to spend excessive effort on the task to be done. You can get everything through a UI-based interface, and everything is sorted and very simple. Over the period of time, the operating system evolution by Microsoft is good for the individual workspace.
