Review of HTB’s Most Challenging Web Security Certification (CWEE)
The CWEE certification is one of the most challenging web security certifications available these days, I hope this review helps future candidates set realistic expectations and avoid common pitfalls when preparing for this demanding exam.
Prerequisites and Background
Before even considering the CWEE certification, you need to have a solid foundation in web security. This isn’t a beginner-friendly certification by any means. You must be well-versed in web attacks and have strong programming skills, as the certification heavily focuses on source code reviews and requires you to write your own exploits from scratch.
Essential prerequisites include:
- Strong programming knowledge, especially Python
- Extensive experience with web vulnerabilities and the OWASP Top 10
- Bug hunting and penetration testing experience
- Comfort with both black-box and white-box testing methodologies
If you don’t have a solid grasp of these fundamentals, I’d strongly recommend gaining more experience before attempting CWEE.
The Training Experience
The CWEE training materials deserve a perfect 10/10 rating. What sets this training apart is its focus on the latest attack techniques for each vulnerability type, along with the real-world challenges you’ll face when exploiting them. The course doesn’t just teach you theoretical concepts—it prepares you for the complexities of actual exploitation scenarios.
The training adequately prepared me for the exam, but there’s one critical success factor: take detailed notes during each lesson. These notes become your lifeline during the exam. The exam contains several rabbit holes designed to waste your time, and your study notes are often the only way to quickly identify the best exploitation scenario and avoid these time traps.
Supplemental Training Resources
While the official CWEE materials are excellent, I found additional practice invaluable:
Assessment Labs: The built-in assessment labs are good for applying what you learn, but I found HackTheBox machines to be the most beneficial supplemental resource.
HackTheBox Academy Integration: You can target specific skills by going to HackTheBox Academy and selecting lessons for particular vulnerability types. For example, if you want to practice Advanced SQL Injection, you can choose different difficulty levels and work through multiple machines with varying complexity levels.
Study Schedule and Commitment
I dedicated 4 hours daily to studying and training, which proved to be sufficient for mastering the material. Consistency is key—regular daily practice is more effective than cramming sessions.
The Nightmare Exam
I would describe the exam difficulty level as nightmare. Here’s what you’re up against:
Exam Structure:
- 3 machines with different applications
- Each machine has its own domain and subdomains
- 1 white-box challenge
- 1 gray-box challenge
- 1 black-box challenge
Exam Duration: 10 days - which might sound generous, but you’ll need every hour.
What Makes It Challenging:
- Multiple rabbit holes designed to waste time
- Requires deep understanding of all vulnerability types covered in training
- Logical bugs that require creative thinking
- Chaining exploits - you need to combine different attack vectors and scenarios
- Must demonstrate complete exploitation chains to capture flags
Deliverables:
- 5 out of 6 flags minimum to pass (90% pass rate required)
- Comprehensive report documenting your methodology
- Working exploit scripts - they will test your scripts to ensure they function properly
Key Success Strategies
- Take meticulous notes during training - you’ll reference them constantly during the exam
- Give yourself adequate practice time - don’t rush into the exam
- Focus on chaining attacks - individual vulnerabilities are just pieces of larger exploitation puzzles
- Practice writing clean, functional exploits - your scripts must work reliably
- Time management - with rabbit holes present, efficient time allocation is crucial
Final Recommendation
Would I recommend CWEE? Absolutely yes - but only if you’re willing to study web exploitation at a very deep level. This certification pushes you beyond surface-level understanding into expert-level web security knowledge.
This certification is perfect for:
- Experienced penetration testers looking to specialize in web applications
- Security researchers wanting to validate their skills
- Bug hunters seeking to formalize their expertise
- Anyone passionate about mastering advanced web exploitation techniques
Fair Warning: This is not a certification to take lightly. The difficulty level is intentionally high, and the time investment is substantial. However, if you’re serious about becoming a web exploitation expert, CWEE will challenge you to reach that level.
The sense of accomplishment after passing this certification is immense, and the knowledge gained is immediately applicable to real-world security testing scenarios. If you’re ready for the challenge and committed to deep learning, CWEE is an excellent investment in your security career.
Remember: Take good notes, practice consistently, and prepare for a challenging but incredibly rewarding journey.
