OSEE Certification
EXP-401: Advanced Windows Exploitation is OffSec’s advanced exploit-development course for experienced security professionals. It focuses on complex Windows vulnerabilities, mitigation bypasses, heap exploitation, vulnerability research, advanced exploit development, and Windows kernel exploitation.
The course is highly practical and requires candidates to analyze vulnerable software, identify security weaknesses, and develop working exploits in modern Windows environments. OffSec currently delivers EXP-401 only through instructor-led, in-person training and does not offer an online version.
Successful candidates can pursue the OffSec Exploitation Expert (OSEE) certification, which validates advanced vulnerability research, exploitation skills, and creative problem-solving.

Frequently Asked Questions
What does the OSEE Certification actually test?
OSEE isn’t about memorising cybersecurity terms. You’re expected to examine vulnerable Windows software, understand what went wrong, and build an exploit that works reliably.
Who is this certification meant for?
It’s mainly for people already working in exploit development, vulnerability research, red teaming, or advanced penetration testing. If debugging and assembly language are new to you, more preparation will be needed first.
Do I need another OffSec certification before OSEE?
OffSec doesn’t require one specific certification. Still, jumping directly into OSEE isn’t usually practical. Experience at the 300 level or similar technical knowledge is strongly recommended.
What should I study for OSEE?
Spend time on Windows internals, C or C++, x86_64 assembly, heap behaviour, memory corruption, and security mitigations. You should also be comfortable using WinDBG and IDA Pro without step-by-step help.
What happens during the exam?
You’ll work on two practical assignments in a controlled lab. The technical part lasts 71 hours and 45 minutes. Once that time ends, you have 24 hours to upload your report. You need 75 out of 100 points to pass.
Is EXP-401 available as an online course?
No. The official EXP-401 course is taught in person. The material is difficult, and learners often need direct help from the instructor while working through the exercises.
How does NYTCC help with preparation?
We first look at what you already know and where you’re struggling. From there, the preparation can focus on the areas that need work instead of covering familiar topics again. This makes study time more useful and easier to manage.
