Rocky Linux and Kali Linux compete in the Linux distribution category, each offering unique features catering to different user needs. Rocky Linux appears to have an upper hand in enterprise environments due to its stability and compatibility with Red Hat, whereas Kali Linux excels in penetration testing due to its comprehensive security toolset.
Features: Rocky Linux is known for its stability, compatibility with Red Hat, and strong community support, making it cost-effective for those migrating from CentOS or Red Hat without additional licensing costs. It also offers long-term support and integration with automation tools like Ansible. Kali Linux stands out for its extensive security toolset, ease of setup for penetration testing, and minimal configuration time, making it advantageous for security professionals.
Room for Improvement: Rocky Linux needs to address missing components after migrating from CentOS, improve security patch updates, and enhance integration with Kubernetes and container management. Kali Linux could strengthen its UI/UX design, integrate AI and ML features, and improve documentation to assist beginners in overcoming a steep learning curve.
Ease of Deployment and Customer Service: Rocky Linux provides smooth deployments across on-premises and hybrid cloud environments, supported by good documentation and community, despite being in the early stages of developing its customer support. Kali Linux is straightforward to deploy on various platforms, including public cloud, but lacks formal support, relying on community resources and documentation for assistance.
Pricing and ROI: Both Rocky Linux and Kali Linux are open-source, eliminating licensing fees and making them cost-effective. Rocky Linux offers significant savings when transitioning from paid options like Red Hat, resulting in a positive ROI. Kali Linux, being free and bundled with security tools, significantly lowers costs for penetration testers and offers a favorable ROI by reducing setup and operational expenses.
Integrating Kali Linux with DevOps tools has resulted in reduced operational costs due to automated test cases, making it a worthwhile investment with significant returns by decreasing the attack surface area and the frequency of attack incidents.
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.
I have saved time by avoiding the lag I sometimes face on the TryHackMe in-built machine, and I have learned more efficiently.
When it comes to return on investment, a lot of money is saved since we moved from a purchased license to the open source provided by Rocky Linux.
Using Rocky Linux reduced server maintenance time by approximately 30-40%, cut licensing costs compared to paid Linux distributions, and lowered deployment issues by 25%.
ROI has been good as we have significant open source community involvement.
Since most of the tools and other things are community-based, the documentation and other community support are very good.
I was able to solve the problems I was experiencing.
The support level is extraordinary, providing on-time assistance.
We have not yet needed to contact a vendor regarding Rocky Linux.
Even if we raise a support ticket, we receive a resolution or a reply from the team within two business days.
You can use it on cloud, VPS, and on-premises.
I would describe Kali Linux's scalability as very scalable because I can deploy it on a range of different machines, whether that is my laptop or using maybe Raspberry Pi or Android.
Regarding the scalability of Kali Linux for my work and projects, whenever I was conducting brute force attacks and provided more than two or three million lines of payload, the system would freeze.
Even if the server is not responding and we want to attach the volume on another instance or a temporary instance, it is very easy and straightforward with no hiccups.
It has handled growth or changing needs well.
Rocky Linux scales very well, from small virtual machines to large clusters.
Due to the huge user base that uses it, it is kept up to date regularly.
Kali Linux is stable for my use cases, though not the latest version.
Kali Linux is very stable for my needs.
Rocky Linux is stable, scalable, and it is very much easier to use.
Rocky Linux is stable.
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.
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.
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.
It is based on customer requirements, as they might want to use Rocky Linux or Ubuntu, depending on their needs.
Rocky Linux could be improved by having more integration with Kubernetes.
Currently, it takes more than one month to release a new package or kernel, so speeding that up would help reduce reported vulnerability remediations.
Kali Linux is free software, an operating system that's available to download without any cost or licensing fees.
I simply create a VM, so there are no costs involved.
My experience with pricing, setup costs, and licensing for Kali Linux has been positive, as it operates under an open-source model.
The lack of a subscription fee saves money while still giving enterprise-grade stability.
We switched to Rocky Linux because of the license price, and in our business, we don't need to have a higher cost as that is not a good idea.
There is no extra cost for a license if we are purchasing Rocky Linux from the AWS Marketplace.
Kali Linux has positively impacted my organization by improving efficiency in penetration testing; its open-source nature permits extensive customization and inclusion of numerous comprehensive pre-installed tools, contributing to a secure network environment with effective monitoring of network applications.
A unique and really helpful feature of Kali Linux, compared to other operating systems, is that many of the offensive security tools are already pre-configured and pre-installed.
Kali Linux positively impacts my organization by allowing us to monitor changes and security posture for the company.
Rocky Linux has positively impacted my organization, specifically through cost savings, because we did not have to buy any licenses or extra licenses of other distros, such as Oracle or Red Hat.
For production deployment, Rocky Linux is a great choice because it offers full RHEL compatibility without licensing costs, along with strong community support.
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.
