OffSec PEN-200 (OSCP)

This hands-on course OffSec PEN-200 (OSCP) class introduces learners to professional penetration testing using Kali Linux. PEN-200 is OffSec’s industry leading course for aspiring ethical hackers and forms the pathway to achieving the prestigious OffSec Certified Professional (OSCP and OSCP+) certifications. Learners will develop deep technical skills through a structured approach to ethical hacking, mastering penetration testing methodology, tools, and techniques in a self-paced learning environment.

The course blends theory with immersive practice, equipping participants with the capability to identify, exploit, and report vulnerabilities across real-world systems. Learners gain access to the OffSec PEN-200 (OSCP) learning content, and labs for 12-months to support their OSCP exam preparation journey.

Prerequisites

While there are no formal prerequisites, learners are strongly advised to have:

• A solid understanding of TCP/IP networking
• Familiarity with Linux and Windows operating systems
• Basic scripting ability in languages such as Bash or Python

To prepare for PEN-200, learners may benefit from completing the OffSec SEC-100: Security Essentials course.

Target audience

This course is aimed at cybersecurity professionals looking to build advanced ethical hacking skills and pursue the OSCP certification. It is particularly suitable for:

• Security analysts, penetration testers, and threat hunters
• IT professionals with prior experience in networking and system administration
• Learners seeking a career transition into offensive security

By the end of the course, learners will be able to:

• Apply penetration testing methodology to assess and exploit system vulnerabilities
• Conduct advanced information gathering and vulnerability analysis
• Exploit common web application vulnerabilities including XSS, SQL injection, and session hijacking
• Execute client-side attacks to compromise browsers and user-facing components
• Locate, customise, and deploy public exploits responsibly
• Write detailed, actionable penetration testing reports with remediation recommendations
• Prepare effectively for the OSCP and OSCP+ certifications through practical, lab-based experience
