Understanding EXP-401 and OSEE Certification
EXP-401: Advanced Windows Exploitation is OffSec’s most advanced Windows exploit-development course. It is designed for experienced security professionals who already have strong knowledge of exploit development and want to work with more complex Windows vulnerabilities and security protections.
The course focuses on advanced areas such as security mitigation bypasses, heap exploitation, vulnerability research, advanced exploit development, and Windows kernel exploitation. Learners are expected to analyze vulnerable software, identify weaknesses, and develop working exploits against modern Windows environments.
Because EXP-401 requires intensive hands-on work and significant instructor interaction, OffSec currently delivers the official course only through in-person, instructor-led training. It does not include an online version.
After completing EXP-401, candidates can attempt the OffSec Exploitation Expert (OSEE) certification exam. The exam is a highly practical challenge that evaluates not only technical knowledge but also the ability to think creatively, identify unfamiliar vulnerabilities, and develop reliable exploits.
Important Training Format Note
OffSec currently delivers the official EXP-401 course only through instructor-led, in-person training. It is a highly intensive course that requires significant interaction between learners and instructors.
PassYourCert provides independent OSEE certification preparation and exam-readiness support. Our preparation should not be considered the official OffSec EXP-401 course.

OffSec currently lists the following upcoming EXP-401 live training:
- Training Dates: November 2–6, 2026
- Location: Veenendaal, Netherlands
- Language: English
- Training Mode: In-person, instructor-led
- Course Level: 400
