About this certification
The GIAC Exploit Researcher and Advanced Penetration Tester (GXPN) certification validates a practitioner's ability to pinpoint and mitigate significant security flaws in systems and networks. GXPN certification holders are qualified to conduct advanced penetration tests that improve system security by modeling the behavior of attackers, leveraging expert knowledge to demonstrate and mitigate the business risk posed by these threats.
The exam covers network-based and cryptography-based attacks, escalation and client-side attacks, handling restricted environments, fuzzing and source code analysis, shellcode and memory basics, defeating advanced stack protections on Windows and Linux, and Windows and Linux stack overflows. It is a hands-on, performance-based certification delivered through GIAC's CyberLive format, ensuring candidates can apply their skills in realistic lab environments.
Who it’s for
This certification is for network penetration testers, systems penetration testers, incident handlers, application developers, and IDS engineers. It is also for security personnel responsible for assessing target networks, systems, and applications to find vulnerabilities. Candidates should have a strong foundation in offensive security concepts and practical experience with penetration testing tools and techniques.
Recommended experience
Practical work experience in penetration testing or related security roles is recommended to ensure mastery of the skills necessary for certification. Hands-on experience with network penetration testing and exploitation; Familiarity with Windows and Linux operating systems and their security mechanisms; Understanding of common attack vectors and mitigation techniques; Experience with scripting or programming for offensive operations

A question, and the idea behind it
Every question comes from a concept
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.
The visual book
See it once. Carry it into the exam.
The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.
It teaches · it does not count
A smartphone uses AI to unlock when the owner looks at the camera. Which AI capability is being used?
AImage classification
BFacial recognition
COptical character recognition
DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.
