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.

Essential for Cybersecurity Pros, Packed with Tools

I use Kali Linux for cyber security and ethical hacking because it has many pre-installed tools. It solves a lot of my problems since on other operating systems, I have to install tools manually one by one, which wastes time. I like that it has all the security tools used in penetration testing. Whenever I need to scan a network, I can easily use pre-installed tools like NMAP, Metasploit, and Wireshark. I also appreciate that I can use it without installing it on a system; just install it on a pendrive, and I can use it anywhere without installing it on any computer. NMAP helps me scan the network and find vulnerabilities, Metasploit helps exploit vulnerabilities, and Wireshark helps capture and inspect data packets, allowing me to analyze the network and monitor suspicious activity.

Powerful Tool for Cybersecurity Pros

I like that Kali Linux comes ready with hundreds of security tools in one system, which is great for learning and practicing ethical hacking. It stays up-to-date, works well on laptops, virtual machines, and even phones, and gives full control over the system. Additionally, I enjoy that it has a strong community and good documentation, making help easy to find. It runs smoothly on virtual machines and live USBs, supports many hardware tools, and is highly customizable, which makes experimenting and learning cybersecurity much easier.
