Rated 5 out of 5 stars

Great course that really helped me land my first job.

I have completed my graduation in the cybersecurity field. I enrolled in the CRTP course, which includes 2 months of lab access. This course primarily focuses on attacking and defending active directory. I thoroughly enjoyed the overall course, but the main highlight for me was how it clarified my understanding of active directory concepts.

The labs simulated real-world attacks, which helped me understand the concepts in depth.
This course is quite advanced and not recommended for absolute beginners. Before this, I had taken some introductory courses, but they were more for starters. I also attempted the CRTP certification. Honestly, it was a great experience to complete this course on my first attempt. Initially, I found the exam challenging and had to reattempt it, but I passed on my second try.

Earning this certification significantly improved my skills and greatly increased my chances of getting interview calls, eventually helping me secure my first job. The website lists many courses, and I reached out to the support team through their Discord channel. They guided me to take the CRTP course first, and I found the support team very intuitive and responsive whenever I encountered issues.

For me, this was a complete and valuable course. I hope to see more beginner-friendly courses in the future. This is a must-take for anyone looking to build a strong foundation and advance quickly in the field.

Great experience with Altered Security’s CRTP Course

I just completed the Certified Red Team Professional (CRTP) course from Altered Security and it was one of the most practical and well put together courses I’ve taken.

The labs were awesome – real active directory attack scenarios that gave me hands on experience.

The course material was clear, up to date and easy to follow. I also liked how the support team responded quickly to my questions in theri discord server. The exam was tough but fair, made me apply everything I learned in the labs.

Overall I highly recommend Altered Security’s CRTP course to anyone looking to improve their red teaming and AD exploitation skills. It’s great value for the knowledge and confidence it gives you.
