The Penetration Testing with Kali Linux (PWK/PEN-200) online ethical hacking course is self-paced. It introduces penetration testing tools and techniques via hands-on experience. PEN-200 trains not only the skills, but also the mindset required to be a successful penetration tester. Students who complete the course and pass the exam earn the Offensive Security Certified Professional (OSCP) certification. This course features five recently retired OSCP exam machines now added to the PWK labs. These five machines represent an entire OSCP exam room.

A Powerhouse for Cybersecurity Professionals

I use Kali Linux for penetration testing, ethical hacking, vulnerability assessment, and cybersecurity research. I appreciate its extensive pre-installed tools, which save me time by providing everything I need in one place. I also like the regular updates and strong community support, as they help me quickly troubleshoot issues and learn new techniques. The customizability is another great feature, allowing me to tailor the OS to my specific testing needs and workflow. These aspects make penetration testing, ethical hacking, and learning cybersecurity much more efficient and accessible, making Kali Linux highly efficient and valuable for cybersecurity work.

Perfect for Penetration Testing, Challenging for Beginners

I use Kali Linux to grow my skills in cybersecurity and learn penetration testing. It helps me find security issues in systems and websites. I appreciate that it has many pre-installed tools, so I don't need to install extra things. Its interface is easy to understand, and the community support is strong, making it easy to find solutions online. The installation process is very easy for me, though partitioning can be confusing if you aren't familiar with operating systems.

Comprehensive Educational Tool with Easy Setup

I use Kali Linux primarily for educational purposes, and I appreciate having a lab with various hacking and cracking methods for demonstration. I find it to be an all-in-one solution and a package of all the things you need for a lab and teaching. I also like that the initial setup was very easy.
