igmGuru's OSED Certification Training prepares security professionals for OffSec's EXP-301 exam through hands-on, instructor-led practice in Windows exploit development, reverse engineering, custom shellcoding, and modern mitigation bypass techniques used today.
✅ Level: Intermediate to Advanced ✅ Instructor-Led Live Training (Duration Customizable - See Below) ✅ 100% Practical, Lab-Driven Windows Exploit Development ✅ Aligned with OffSec's Official EXP-301 / OSED Exam Blueprint ✅ Hands-on WinDbg, IDA Pro, Shellcoding & ROP Labs ✅ Trainers with Offensive Security & Red Team Experience
The OSED (OffSec Exploit Developer) Certification training by igmGuru is built around OffSec's EXP-301: Windows User Mode Exploit Development course. This training program equips you with practical skills in x86 assembly, WinDbg debugging, stack and SEH overflow exploitation, egghunters, custom shellcoding, and DEP/ASLR bypass. Guided by experienced exploit development trainers, this program prepares you for the demanding OSED certification exam and real-world offensive security roles across red-teaming, vulnerability research, and malware analysis.
OffSec does not enforce a formal prerequisite for EXP-301, but candidates get the most value when they arrive with:
Most security certifications teach candidates to run existing exploits. OSED teaches you to build them. It moves you past Metasploit modules and pre-written payloads into the mechanics that make an exploit work, corrupting memory precisely, writing shellcode that fits in a constrained buffer, and getting code execution past DEP and ASLR without any public tool doing the heavy lifting for you.
Because it demands genuine skill rather than checklist knowledge, OSED is recognized across the offensive security industry as a credible signal of exploit-development ability. It also forms one-third of the OSCE³ credential alongside OSEP and OSWE, making it a natural next step for OSCP holders who want to specialize in binary exploitation, vulnerability research, or malware reverse engineering rather than general penetration testing.
This training is designed to help you:
Across the program, you will work through:
This training fits professionals such as:
By the end of this course, you will be able to:
OSED-certified professionals are well positioned for roles such as:

OSED (OffSec Exploit Developer) is a practical certification from OffSec, earned by completing the EXP-301 course and passing its proctored exam. It validates hands-on skill in Windows user-mode exploit development, including reverse engineering, custom shellcoding, and mitigation bypass.
Yes - it's a 300-level exam that requires you to independently reverse engineer binaries and build working exploits under time pressure, without relying on pre-built tools. Consistent lab practice and a methodical exam approach make a significant difference.
There's no formal prerequisite, but OffSec recommends familiarity with a debugger, basic 32-bit exploitation concepts, Python 3, and the ability to read C and x86 Assembly. Many candidates complete OSCP first.
No. Unlike some newer OffSec credentials, OSED does not expire once earned.
OSCP is not a mandatory prerequisite, but it's a widely recommended starting point, since it builds the foundational buffer-overflow and Windows exploitation skills that EXP-301 builds on.
Candidates get 47 hours and 45 minutes to complete three exploit-development tasks, followed by a further 24 hours to submit documentation.
OSCP focuses on broad penetration testing methodology, and OSEP focuses on advanced evasion and lateral movement. OSED is narrowly and deeply focused on Windows exploit development itself - reverse engineering, shellcoding, and mitigation bypass - making it the most technically specialized of the three.
