Overview

Evasion Techniques and Breaching Defenses (PEN-300) is an advanced penetration testing course. Learners who complete the course and pass the exam will earn the OffSec Experienced Pentester (OSEP) certification. This course builds on the knowledge and techniques taught in Penetration Testing with Kali Linux, teaching learners to perform advanced penetration tests against mature organisations with an established security function and focuses on bypassing security mechanisms that are designed to block attacks. The OSEP is one of three certifications making up the OSCE³ certification along with the OSWE for advanced web attacks and OSED for exploit development.
