Sentiment score
5.7
Kali Linux improves security and efficiency with low-cost tools, offering significant cost savings and optimized resource management.
The clearest measurable benefit is avoiding operating system subscription costs while maintaining enterprise Linux compatibility and stability.
Associate Systems Engineer at Dhanyaayai Enterprises Pvt Ltd
We saved approximately 70% of our budget with AlmaLinux, and the system is stable and reliable.
Systems Engineer at SARL Rajafood
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.
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.
SWE-1 at a tech vendor with 10,001+ employees
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.
Cloud Security Architect at a tech services company with 10,001+ employees
Kali Linux is a time-saving and cost-saving solution.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees

Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
Kali Linux could improve with a user-friendly GUI, enhanced support, better documentation, AI integration, and optimized VM images.
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.
Devops Engineer at EDAG
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.
Cloud Ops Lead at a tech vendor with 10,001+ employees
 

Setup Cost

AlmaLinux offers enterprises a cost-effective, stable, and RHEL-compatible platform with free updates and no licensing fees.
Kali Linux is cost-effective and appealing for enterprises with its open-source, free access, and comprehensive tool suite.
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 itself is free and open-source, so there is no OS licensing fee.
Technical Solution Development Engineer at Ericsson
AlmaLinux is free, so there are no costs there.
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
We do not need to pay anything.

Valuable Features

AlmaLinux offers enterprise-grade stability, security, and cost savings with RHEL compatibility, enhanced by TuxCare support and KernelCare integration.
Kali Linux offers pre-installed security tools, user-friendly interface, and customization, ideal for ethical hacking and penetration testing.
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
At this moment, AlmaLinux is a very open platform. It not only includes the latest security patches but also integrates very recent AI technologies alongside the direct patches that help harden the server.

Featured Reviews

Arka A - PeerSpot reviewer
Technical Solution Development Engineer at Ericsson
Enterprise workloads have run reliably while operations have reduced costs and simplified patching
AlmaLinux is already very strong, but it could be improved in a few areas. Better centralized management and monitoring, easier major version upgrades, and more enterprise-focused automation tools would make administration simpler. Having more integrated tools for patch management, compliance, configuration management, and troubleshooting could reduce manual work for system administrators. The main area for improvement is enterprise management. Better centralized patching, monitoring, compliance, and automation would make it easier to manage large-scale deployments. I would also like to see smoother and more predictable major version upgrades, especially for systems with third-party dependencies. AlmaLinux is already improving in this area through ELEvate and its migration tools.
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.
