WEB-300: Advanced Web Attacks and Exploitation
OSWE Certification
Advanced Web Attacks and exploitation (WEB-300) is an advanced web application security course that teaches the skills needed to conduct white box web app penetration tests. Learners who complete the course and pass the exam earn the OffSec Web Expert (OSWE) certification and will demonstrate mastery in exploiting front-facing web apps. The OSWE is one of three certifications making up the OSCE³ certification along with the OSEP for advanced pentesting and OSED for exploit development.
