What is the CRTL Certification?
The Certified Red Team Lead (CRTL) certification is awarded to individuals who complete Zero-Point Security’s "Red Team Ops II" (RTO-2) course and pass its rigorous exam [1][2]. This certification demonstrates expertise in bypassing modern Windows endpoint defenses, especially when standard techniques fall short [2][3].
Building on the foundational skills from the Certified Red Team Operator (CRTO) certification, the CRTL focuses on advanced Operations Security (OPSEC) and defense evasion techniques. Instead of revisiting basic Active Directory attack methods, it challenges candidates to operate stealthily in highly secured environments like those found in government and defense networks. These environments are fortified with Endpoint Detection and Response (EDR) systems, Attack Surface Reduction (ASR) rules, and Windows Defender Application Control (WDAC) [2].
Andres Roldan, VP of Hacking at Fluid Attacks, highlights the certification’s focus:
"RTO-2 was born to compliment RTO on the OPSEC realm… focusing on advanced OPSEC tactics, including bypassing modern enterprise Windows endpoint controls" [2].
To earn the certification, candidates must develop custom offensive tools using C++ and C#. These tools are designed to evade signature-based and behavior-based detections, leveraging advanced techniques like API unhooking, indirect syscalls, and process injection. Mastery of these methods sets apart a red team leader from a standard operator [2][5].
Key Features of the CRTL
The CRTL certification tests your ability to execute red team operations in simulated Active Directory environments that replicate the security measures of high-security networks. To pass, candidates must capture all required flags in the exam. Earlier versions of the exam required capturing 4 out of 4 flags within a 5-day lab, while newer versions demand 5 out of 6 flags within 8 days, with a total lab runtime of 72 hours [1][2][4]. This all-or-nothing approach ensures candidates demonstrate both technical depth and persistence under pressure.
The certification evaluates skills across six core domains:
| Skill Category | Core Skills |
|---|---|
| C2 Infrastructure | Building secure on-premise command and control systems, configuring HTTP/DNS redirectors, and managing SSL certificates for Beacons |
| Tooling Development | Writing custom loaders and using Windows and NT APIs via C++ and C#, including P/Invoke and D/Invoke techniques |
| Process Injection | Techniques like APC injection, section mapping, and utilizing undocumented ntdll.dll functions for remote process code injection |
| Defense Evasion | Methods such as bypassing Event Tracing for Windows (ETW), PPID spoofing, command line spoofing, and thread stack spoofing |
| Security Controls | Identifying and exploiting weaknesses in ASR and WDAC implementations |
| EDR Evasion | Techniques like API unhooking, indirect syscalls, and unregistering kernel callbacks |
The exam environment is intentionally designed with unexpected challenges not covered directly in the course material. Candidates must perform independent research into topics like EDR bypasses, YARA rules, and whitepapers. As Ibad Altaf, a penetration tester, explains:
"This section [EDR evasion] requires a lot of research about the EDR itself, reading up the yara rules, reading blogs, articles, as well as whitepapers and coming up with your own methods to bypass EDR detections" [5].
Unlike certifications that focus on rote memorization, the CRTL emphasizes problem-solving and tool customization. A reviewer from six-two.dev shared their experience:
"The exam was very fun and I learned about one new tool. Personally I liked it much more than the CRTO exam, since it required some thinking and not just copying commands from the course material" [1].
These advanced skills provide a pathway to career growth, as they not only validate technical expertise but also prepare candidates for leadership roles in high-security environments.
Why CRTL Matters for Cleared Professionals
For professionals working in government and defense sectors, the CRTL certification equips them with the skills to lead red team operations against advanced threats. With Active Directory in use by over 90% of Fortune 1000 companies [6], the techniques learned – such as bypassing ASR, WDAC, and Protected Processes – are essential for operating in secured environments [2].
The certification transitions candidates from technical operators to research-driven leaders capable of overcoming specific security challenges in EDR-protected Active Directory forests [5]. It teaches how to set up complex command and control (C2) infrastructures with multiple redirectors, implement safeguards to prevent payload misuse, and maintain stealth during extended engagements [5].
Ben S. from infosecnoodle captures the certification’s value:
"RTO2 teaches you how to perform successful attacks in hardened network environments, going up against modern EDR solutions and blue teams" [4].
For professionals leading red team exercises in classified systems, the CRTL emphasizes using legitimate Windows features over traditional exploits. This approach is particularly effective in fully patched environments, where abusing built-in functionalities while staying undetected often determines the success of an operation.
Eligibility and Prerequisites for the CRTL Certification
Security Clearance Requirements
If you’re aiming for a role in government or defense sectors, having an active security clearance is non-negotiable. To qualify as a Cleared Red Team Lead, you must hold a Secret or Top Secret clearance [7]. These clearances are issued through a National Security Eligibility Determination, which evaluates whether granting you access to classified information aligns with U.S. national security interests [7].
The process to obtain a clearance is thorough and time-consuming. Typically, it takes 9 to 12 months to complete [8]. The U.S. Department of State’s Diplomatic Security Service handles over 38,000 vetting actions annually [7]. During this process, you’ll need to disclose details like criminal history, financial issues, or foreign contacts [9]. Failing to provide full transparency can result in immediate disqualification.
Prior Certifications and Experience
A strong technical background is just as essential as security clearance. Candidates must have successfully completed the CRTO exam, as the skills it covers serve as the foundation for the CRTL certification. According to Andres Roldan, RTO-2 builds on these red team skills, so a solid understanding of the basics is a must [2].
To qualify for the CRTL, you need to demonstrate expertise in Active Directory (AD) exploitation, including techniques like Kerberos attacks (Golden/Silver tickets and constrained delegation), lateral movement, privilege escalation, and the use of trusted tools like Cobalt Strike C2 [2][3]. Cyber Security Researcher Brahim Chebli highlights the importance of this background:
"This background [in red teaming and malware development] played a crucial role in passing the exam, as CRTL doesn’t cover basics, especially AD attacks, lateral movements, and using Cobalt Strike C2" [3].
Programming knowledge is another key requirement. You’ll need proficiency in C# and C++ to create custom offensive tools and interact with Windows APIs. Familiarity with Visual Studio for compiling and debugging is critical, as the exam may involve troubleshooting tools in restricted environments [2][10]. If you lack experience in malware development, consider completing Maldev Academy before attempting RTO-2 [5].
This certification is designed for those with established red team expertise, preparing candidates for leadership roles in highly secure environments. Once you’ve met these prerequisites, the next step is diving into the exam’s format and structure.
CRTL Certification Exam: Format and Structure
Exam Overview
The CRTL exam is a fully hands-on practical test, conducted in a hardened, multi-forest Active Directory environment [2][4]. It offers 72 hours of active lab time, which you can use flexibly over several days. The timer only runs when the lab is active, so you can pause the environment to rest or do additional research without wasting time [2][11][4].
This exam follows a flag-based structure rather than traditional questions. To pass, you typically need to capture all 4 flags [2][11][4]. However, recent updates for 2024 suggest that the format may now require 5 out of 6 flags to be captured within an 8-day window [1]. Unlike other certifications that sometimes allow partial credit, CRTL demands full completion of the required flags.
The exam is hosted on the Cyber Ranges platform (formerly Snaplabs) and accessed via a web browser using Apache Guacamole [11][4]. You’ll need to be familiar with Visual Studio and C#/C++ development, as modifying or compiling custom tools is often necessary [11][4]. While you’re given 72 hours, many candidates complete it in 11 to 30 hours of active time [2][4]. This hands-on format sets the tone for the unique scoring process, which is covered next.
Scoring and Post-Exam Process
Once you’ve completed the challenges, the scoring process offers immediate feedback. Flags are entered into an automated system that verifies them in real time [2][4]. Unlike many other advanced security certifications, there’s no written report requirement. As Roldan explains:
"You don’t need to write a report, just enter the flags" [2].
The certification badge is typically issued 5 days after the exam starts or once the exam window closes [2][11][4]. Ben S. from infosecnoodle praises this streamlined approach:
"One of the great things about Zero-Point Security exams is that you pretty much know when you’ve passed because it’s entirely flag-based. If you get all the flags, you pass" [4].
To avoid losing lab time, make sure to refresh the exam dashboard every 30 minutes. This prevents the environment from shutting down due to inactivity [11]. Staying mindful of this ensures you can make the most of your allocated time.

Key Skills to Master
The CRTL exam pushes you to excel in defense evasion within a hardened enterprise environment. You’ll need to bypass tools like Elastic EDR and Windows Defender, where typical techniques won’t cut it.
A solid grasp of offensive tooling is non-negotiable. You’ll need to work with C++ and C# in Visual Studio to create custom tools and interact with Windows APIs using P/Invoke and D/Invoke. This isn’t about running pre-built scripts – it’s about compiling, debugging, and tailoring offensive tools. Mastering process injection methods, such as injecting into remote processes, leveraging undocumented ntdll.dll functions, and using Asynchronous Procedure Call (APC) dispatching, is essential.
You’ll also need to outsmart Windows security measures. This includes bypassing Attack Surface Reduction (ASR) rules, Windows Defender Application Control (WDAC), and Protected Processes (PPL). In-memory evasion techniques like thread stack spoofing and sleep masks will help you maintain access without detection.
Finally, building resilient C2 (Command and Control) infrastructure is critical. This involves configuring Apache redirect rules, managing SSL certificates, and implementing failover strategies for beacons – all while maintaining operational security in a closely monitored setting.
To refine these skills, focus on targeted training and hands-on labs.
Recommended Resources and Labs
The Red Team Ops II (RTO-2) course by Zero-Point Security is your go-to resource. It costs around £399.00 (approximately $490) and includes both the course and exam voucher.
