Cloud Security Architect at a tech services company with 10,001+ employees4.0I rely on Kali Linux for security and penetration testing, valuing its built-in tools, open-source nature, and cloud deployment for efficiency. However, I desire better tool documentation, improved UI, and less default root usage for a more versatile experience.
Product security engineer at a tech vendor with 10,001+ employees4.0I use Kali Linux for offensive security and learning, valuing its pre-configured tools and customization. While great for me, it's not beginner-friendly, and I find its latest versions unstable, preferring older ones for stability and reliable VM images.
Cloud Ops Lead at a tech vendor with 10,001+ employees5.0I use Kali Linux for ethical hacking to secure my applications, finding it a stable, all-in-one solution with significant security and financial benefits. While it offers excellent value, its steep learning curve is a notable challenge.
Consultant at Cognizant3.5I use Kali Linux daily for security tasks, valuing its pre-installed tools for pen-testing and ISO 27000 certification. It's stable, but I need external resources due to outdated tools and a lack of examples, as direct support is unavailable.
Senior Technical Manager at a tech vendor with 10,001+ employees4.0I rate Kali Linux highly for real-time backend service vulnerability scanning, essential where other tools fail. While its toolset is good and it's scalable, I require enhanced customized port scanning for DMZ zones, which remains a key area for improvement.
Security Researcher at a consultancy with 10,001+ employees4.0I find Kali Linux excellent for ethical hacking and VAPT, offering faster performance with pre-installed tools. Its scalability and cost savings are significant, though a CLI-only bundle would be ideal for me.
Associate Cybersecurity Analyst at a university with 10,001+ employees4.5I use Kali Linux extensively for penetration testing and red teaming, appreciating its vast built-in toolset, especially for reconnaissance. While generally stable and highly valuable, I've noted occasional smoothness issues when multitasking. Overall, I rate it 9/10.
