Beat user mode mitigations
Bypass and evade the security mitigations that protect user mode code on Windows.
Partners and press
Overview
Public exploits stop at the mitigations. OSEE starts where they do.
OSEE is OffSec’s level 400 exploitation expert credential, earned through EXP-401 and built for experienced penetration testers. The 72-hour proctored lab exam asks you to find and exploit unknown vulnerabilities in a controlled lab, then write a report. OffSec calls the course its most challenging and teaches it in person only, and recommends its 300-level credentials first.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
