ROI

Sentiment score
4.4
Organizations using AlmaLinux benefit from cost savings, efficient management, long-term support, and positive investment sentiment despite limited metrics.
Sentiment score
5.8
Kali Linux offers cost-effective security tools with DevOps integration, saving time and resources without upfront costs.
Moving over to AlmaLinux saves a lot of time because of the long-term support, meaning I do not have to support the latest version every couple of years.
The most immediate benefit has been the elimination of licensing and subscription fees compared to commercial enterprise Linux distributions or Windows.

Room For Improvement

AlmaLinux users face challenges with support, documentation, updates, resource allocation, and integration, seeking improvements in security and package availability.
Kali Linux needs improved usability, stability, and community support, with enhancements in security, documentation, and AI integration.
The AlmaLinux team can look into this and see what they can improve in terms of resource consumption and monitoring tools that can actually help the users of AlmaLinux pinpoint the exact processes or services that are causing that amount of resource consumption.
DevOps at a energy/utilities company with 501-1,000 employees
If something is added to AlmaLinux that allows for some subscription or makes it exactly equal to RHEL, it would be perfect.
Azure Dev Ops Engineer at a engineering company with 5,001-10,000 employees
If AlmaLinux could provide ten to twenty years of fixes, that would be an improvement because I do not want to update the system all the time, as it becomes more challenging for me as a system administrator to track all the patches and everything I should patch on the system.
system administration | DevOps | Softrware Developer at a tech vendor with 11-50 employees
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.

Setup Cost

Enterprise users find AlmaLinux cost-effective for budget management, offering free setup, support, and updates as an open-source alternative.
Kali Linux is cost-effective for enterprises, primarily free but offers a perpetual license option for enterprise versions.
In the open-source environment, I believe a Linux distribution is always free of cost.
Junior Software Test Automation Engineer at a consultancy with 51-200 employees
AlmaLinux is free, so there are no costs there.
I have no licensing cost, which means there is no burden related to licensing.
Open Shift Engineer at Dhanyaayai enterprise private limited
I simply create a VM, so there are no costs involved.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
My experience with pricing, setup costs, and licensing for Kali Linux has been positive, as it operates under an open-source model.
SWE-1 at a tech vendor with 10,001+ employees
The pricing and the deployment, resource usage are all spot on and clearly defined, making it helpful and useful for me to deploy and calculate costs.
Cloud Security Architect at a tech services company with 10,001+ employees
 

Valuable Features

AlmaLinux improves PHP management, ensuring stability, security, and cost efficiency with RHEL compatibility, ideal for production environments.
Kali Linux excels in security tools, seamless installation, and customization, making it ideal for ethical hackers and IT professionals.
The tooling stability for DevOps is also significant, allowing easy use of infrastructure as code with Ansible or scripting playbooks that remain valid for years, making it especially important for the CI/CD pipelines.
system administration | DevOps | Softrware Developer at a tech vendor with 11-50 employees
Because AlmaLinux is binary compatible with Red Hat, it provides a very stable and reliable operating system suitable for production environments.
Ingénieur Systéme at Groupe Open SA
The prompt patching and OS updates with AlmaLinux have helped our team by improving our FedRAMP compliance and vulnerability scan reports.
Cloud Software Engineer at Coupa Software
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.

Featured Reviews

Naim Khan - PeerSpot reviewer
DevOps Engineer at SMC Labs, LLC
Private cloud practice has become seamless and deployments run smoothly for my projects
I follow the documentation for AlmaLinux, which I believe could be more extensive for enterprise setups. My primary use case remains deploying private cloud infrastructure using OpenStack Yoga, thus suggesting improvements to cater to specific cloud instances like AWS Graviton or Azure NVMe. Driver or kernel updates for new hardware or cloud instances like AWS Graviton or Azure NVMe tend to arrive a little later in AlmaLinux than they do in the Red Hat distribution. Therefore, I suggest that faster releases of cloud-optimized images and updated hardware drivers could enhance AlmaLinux's competitiveness. Additionally, I find it sometimes difficult to find answers on forums due to the community not being as large as that of Red Hat or CentOS. My suggestion is to create an active forum or Q&A session where developers can directly address user problems, growing the community and providing optional enterprise support tiers for large organizations. Additionally, I have continued to consider improvements. For server administration and language runtime management, I encountered conflicts on production servers with older and newer versions of tools such as Python and Node.js. Simplifying the application space management would reduce the friction in multi-language development environments. Moreover, including more pre-configured or auto-remediation scripts like CIS Benchmark or STIG compliance would be immensely helpful for enterprise security hardening.

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.
