OSCE Certification Requirements and Prerequisites
OSCE³ Certification Requirements: Three Paths to Advanced Penetration Testing Mastery
To earn the OSCE³ certification, you must complete three advanced certifications: OSWE, OSEP, and OSED. Once these are achieved, you’ll automatically receive a printed certificate, wallet card, and challenge coin – no additional exams required [4].
"Earning all three of the following certifications automatically grants you the new OSCE³ certification… No additional exam will be required once you have obtained the other three standalone certifications." – OffSec Support [4]
Here’s a closer look at the certifications and the skills they focus on.
Required Certifications and Skills
Each certification hones in on a specific area of offensive security:
- OSWE (WEB-300): Specializes in white-box web application penetration testing. You’ll need to analyze large codebases and identify vulnerabilities like SQL injection, XSS, and Remote Code Execution [1].
- OSEP (PEN-300): Focuses on advanced evasion techniques for bypassing hardened defenses, including antivirus evasion and lateral movement within networks [1].
- OSED (EXP-301): Centers on Windows user-mode exploit development. This includes reverse engineering with tools like IDA and WinDbg, and crafting ROP chains to bypass protections such as ASLR and DEP [1].
While the OSCP certification isn’t a formal prerequisite, it’s often considered the starting point for this advanced learning path [4]. To succeed, you’ll need a strong foundation in TCP/IP networking, Windows and Linux administration, and scripting skills in Bash or Python [7]. For OSWE, the ability to read and analyze web application code is critical, while OSED demands proficiency in C and Assembly. Each certification exam consists of a challenging 48-hour proctored session, followed by a 24-hour reporting phase [1].
| Certification | Course Code | Focus Area |
|---|---|---|
| OSWE | WEB-300 | Web application penetration testing and code analysis |
| OSEP | PEN-300 | Evasion techniques and lateral movement |
| OSED | EXP-301 | Exploit development and mitigation bypass |
Considerations for Cleared Professionals
While government security clearance isn’t required for OSCE³, cleared professionals should keep a few logistical factors in mind. The exams are proctored, requiring a reliable internet connection and the use of specific proctoring software [9]. If you work in a restricted environment like a SCIF, it’s best to schedule your exam outside of work hours.
The OSEP course is particularly relevant for professionals in environments with mature security functions, such as government or defense sectors. It mirrors the challenges of breaching hardened systems, often protected by enterprise-grade defenses [3]. Cleared professionals may find it helpful to schedule the 48-hour exams during leave periods to avoid conflicts with job responsibilities. Additionally, your experience with advanced security functions and tools like EDR systems can be a strong advantage when tackling the OSEP exam.
How to Prepare for OSCE Certification
Getting ready for OSCE³ means tackling three distinct exams – OSWE, OSEP, and OSED – each requiring its own set of skills. The PEN-300 course alone offers over 615 hours of content, so having a structured, long-term plan is crucial, especially if you’re balancing it with a demanding work schedule [11]. Instead of memorizing tools, focus on building repeatable methodologies to handle the 48-hour exam effectively. Below, we’ll look at how each training path aligns with the requirements of the OSCE³ exams.
Recommended Courses and Training Paths
OffSec provides three main courses that correspond directly to the OSCE³ exams:
- WEB-300: Prepares you for the OSWE certification by focusing on web application testing. It covers source code analysis, chaining vulnerabilities, and tools like Burp Suite and Nikto.
- PEN-300: Helps you earn the OSEP certification by teaching advanced evasion techniques, lateral movement, antivirus bypassing, and Active Directory attacks.
- EXP-301: Focuses on Windows exploit development for the OSED certification. It includes training on tools like WinDbg and IDA, creating custom shellcode, and bypassing protections like ASLR and DEP.

Study Tips for Cleared Pen Testers
Once you’ve selected your training path, refine your study habits to maximize efficiency. Strong documentation skills are critical, as your exam report must be detailed enough for a technically skilled reader to replicate every step of your attacks. Practice documenting commands, custom scripts, and console outputs during your lab sessions. Keeping a "Failure Log" can also help you learn from unsuccessful exploits.
Set specific goals for each study session. For instance, focus on mastering a particular privilege escalation method within 20 minutes. The Pomodoro Technique – working in 25-minute sprints – can help maintain focus during extended study periods. Additionally, organize a searchable knowledge base to quickly reference syntax or commands during the high-pressure exam.
Use the final challenge labs in each course to test your readiness. These labs are designed to reflect the complexity of the actual exams. If you have experience working in cleared environments with hardened systems and enterprise-grade defenses, you already have a strong foundation that will serve you well during the exams. Keep in mind that certain tools are prohibited during exams, such as AI chatbots like ChatGPT, automated tools like SQLmap (restricted in OSWE but allowed in OSEP), and commercial tools like Cobalt Strike [10][5].
Managing Certification Prep with Cleared Work Commitments
Balancing certification prep with cleared assignments requires careful planning. The 48-hour proctored exams demand a stable internet connection and cannot be taken in restricted environments. Schedule your exam attempts during planned leave or less demanding work periods when you’re not required at a secure facility. Use the 24/7 lab access to study during evenings or weekends when secure facility restrictions don’t apply.
If your employer offers workforce development programs, ask about Learn Enterprise subscriptions. These provide structured training for teams, along with multiple exam attempts [1][6]. Additionally, communicate your certification goals with your supervisor – they may be able to offer dedicated study time or flexible scheduling to support your preparation.
