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.

Free, Lightweight OS with Pre-Installed Security Tools

I like that Kali Linux provides pre-installed security features. It's also lightweight software, so it runs smoothly for me. Additionally, I find it easy to install, which is a plus.

Ideal for Penetration Testing, User-Friendly Setup

I use Kali Linux for penetration testing and find it beginner-friendly due to its GNOME desktop environment. The overall terminal experience is good, and even though I use kitty for the terminal, Kali Linux's default configuration works well. I like that all the installed tools are good enough for penetration testing, and everything is pre-installed in one place, which saves me the trouble of installing tools individually. It provides a Python environment without needing to set it up. The readymade hacking tools, such as Burp Suite, and the default optimization are beneficial, especially when running the OS in a virtual machine where memory and hardware are limited. Setting up Kali Linux was very easy, much simpler than other penetration testing OS like Parrot, due to its user-friendly GUI installation process.
