GIAC Exploit Researcher and Advanced Penetration Tester (GXPN) Certification Training Course
Prepare for the GIAC Exploit Researcher and Advanced Penetration Tester (GXPN) exam with hands-on work in network attacks, crypto flaws, fuzzing and exploit writing on Linux and Windows.
What the GXPN course covers and who it's for.
Accumentum's GXPN prep course is for experienced penetration testers, exploit developers and red team members who want to go past standard testing. GIAC says GXPN validates a practitioner's ability to pinpoint and mitigate significant security flaws in systems and networks.
The course follows GIAC's published GXPN objectives. You'll cover network access and infrastructure attacks, traffic interception, practical cryptography, endpoint escapes and escalation, offensive scripting, fuzzing, and Linux and Windows memory, shellcode and exploit mitigation bypasses. GXPN includes CyberLive hands-on questions, so you'll be in a lab for most of it.
Accumentum is an independent training provider. We are not affiliated with, endorsed by or a partner of GIAC. GIAC sets the exam rules, fees and scoring, so check giac.org before you register for your attempt.
Get ready for GXPN the way the exam actually tests.
Cover Every GXPN Objective
Work through each certification objective GIAC publishes for GXPN, in an order that builds on itself.
Practice Hands-On
GXPN includes CyberLive questions that run in real virtual machines, so labs are part of every module.
Build an Open-Book Index
GIAC exams are open book. We help you build and test the index you'll bring into the exam.
Know the Exam Before You Sit It
GXPN is 60 questions in 3 hours with a minimum passing score of 67%, per GIAC. We pace practice to match.
Who Should Attend
- Network and systems penetration testers.
- Exploit developers and red team members.
- Incident handlers and IDS engineers who analyze exploit code.
- GPEN, PenTest+ or CEH holders ready for an advanced next step.
Prerequisites
- There are no Accumentum enrollment prerequisites and GIAC doesn't require any to sit GXPN.
- This is an advanced course. You should already know penetration testing, Linux and Windows, and TCP/IP well. Python scripting and the ability to read C code help a lot, and GPEN level knowledge is a good starting point.
The GXPN course in 6 modules.
Each module maps to one or more of GIAC's published GXPN certification objectives.
- Spotting weak cryptographic implementations
- Exploiting those implementation flaws
- Breaking out of restricted environments
- Bypassing common endpoint protections
- Escalating privileges
- Writing and adapting small, objective focused scripts
- Building fuzzing grammars and knowing when to use them
- Using source code to improve fuzzing coverage
- Linux memory and low level binary execution
- Shellcode foundations
- Return oriented chains for execution
- Bypassing Linux exploit mitigations
- Windows execution and memory foundations
- Overflows and structured exception handling
- Bypassing Windows memory protections
Built for the hands-on side of GXPN.

About the GIAC GXPN exam.
GXPN Exam Readiness
Every objective GIAC publishes for GXPN has a lesson and a lab in our course, so you know exactly what you've covered before you book.

Per GIAC, the GXPN exam is one proctored exam with 60 questions, a 3 hours time limit and a minimum passing score of 67%. It's web based and proctored online through ProctorU or onsite at Pearson VUE.
GIAC certifications renew every four years, with CPE credits or by taking the exam again.
GIAC can update exam specs, so confirm the details for your attempt in your GIAC account. Full details are on GIAC's GXPN page.

The full GIAC GXPN objective list.
GIAC publishes 14 certification objectives for GXPN. Each one below uses GIAC's own wording, and our course maps a lesson or lab to every one of them.
Bypassing Linux Exploit Mitigations
The candidate will be able to identify Linux stack protections and recognize how to bypass them.
Bypassing Windows Memory Protections
The candidate will be able to identify Windows stack protections and describe how to bypass them.
Endpoint Control Evasions and Escalation
The candidate will be able to apply an array of techniques to bypass and break out of common endpoint protections and restrictions.
Establishing Network Access
The candidate will demonstrate knowledge in enumeration and bypass of common network access controls and segmentation architectures that can be used to gain initial connectivity on a network.
Infrastructure Manipulation and Exploitation
The candidate will demonstrate an understanding of how routing and traffic control can be influenced to exploit networks.
Linux Execution, Memory, and Shellcode Foundations
The candidate will be able to describe Linux memory organization and management fundamentals, low-level Linux binary execution, and how to use this information with shell code.
Practical Cryptography
The candidate will be able to identify issues in cryptographic implementations and different ways to exploit those implementations.
Practical Scripting for Offensive Operations
The candidate will be able to create new, and adapt existing, small objective-focused, scripts.
Product Security Testing and Fuzzing Foundations
The candidate will be able to build fuzzing grammars and know when and how to use them.
Return Oriented Stack-Based Exploits
The candidate will be able to create simple return-oriented chains to achieve execution.
Source Code Based Fuzzing Techniques
The candidate will be able to demonstrate the use of available source code to improve fuzzing efficiency and ensure greater code coverage.
Traffic Interception and Manipulation
The candidate will be able to describe the process of intercepting, observing, and altering traffic flows.
Windows Execution and Memory Foundations
The candidate will be able to describe the low-level Windows execution process as well as run-time and execution-time protections.
Windows Overflows and Execution Control
The candidate will be able to demonstrate how execution control can be gained by leveraging internal Windows mechanisms, such as structured exception handling.
A practical path to GIAC GXPN.
GIAC lists the GXPN objectives alphabetically, not in study order. We teach them in an order that builds, starting with network and crypto attacks and working up to Linux and Windows exploit writing, and every block ends with labs before you move on.
Treat each objective as a pass or fail check. If you can explain Return Oriented Stack-Based Exploits to a teammate and do it in a lab, mark it done and move to the next one.
GXPN is an advanced exam. Even if you already test networks every day, plan on steady weekly study over a few months, with extra time for the Linux and Windows exploit work. The objective list is the checklist we hold you to.

How the GIAC GXPN exam works.
The GIAC GXPN exam is one proctored exam with 60 questions and a 3 hours time limit. GIAC sets the minimum passing score at 67%.
Testing runs through ProctorU for remote attempts or Pearson VUE for a test center seat.
GXPN includes CyberLive hands-on questions, which GIAC describes as performance based challenges in realistic lab environments. That is why our course leans so hard on labs.
Plan your weeks around the objectives above. When you can explain each one in your own words and do it in a lab, you are ready to book.
Where GIAC GXPN can take you.
GXPN fits senior penetration testers, red team members and exploit developers. It shows you can get onto a network, attack crypto and endpoint controls, find bugs with fuzzing and write exploits that get past modern Linux and Windows protections.

BLS also projects employment of information security analysts to grow 21 percent from 2025 to 2035, much faster than the average for all occupations. Treat it as a reference point and not a promise.
