Velma Anangwe
Student of CRTP
Completing the CRTP certification with Altered Security was a challenging and rewarding experience. It pushed me to think more critically.
The hands-on exam strengthened my practical skills in Active Directory enumeration, privilege escalation, Kerberos attacks, ACL abuse, persistence, and domain/forest attacks. I particularly appreciated the realistic, fully patched environment, which challenged me to think beyond individual vulnerabilities and understand how different attack paths can be chained together. A great experience that significantly strengthened my red team and Active Directory security skills. Thank you, Altered Security!
Mohamed Ezzahraoui
Student of CRTE
CRTE (Certified Red Team Expert), the advanced continuation of CRTP from Altered Security, has earned an excellent reputation within the offensive security community, and after completing it, I can confidently say it deserves that recognition. After the recent update introducing Windows Server 2025, dMSA, AES256-signed Kerberos tickets, and a modern defensive stack, I knew it was the perfect time to take it. The lab environment was one of the highlights of the cours. I was able to combine native Windows/.NET tooling with my preferred Linux toolkit: Impacket, bloodyAD, and NetExec, which I find invaluable - not only from an OPSEC perspective but for the operational flexibility and adaptability they deliver when working within Active Directory environments. Thanks to Nikhil Mittal and the Altered Security team for building such a practical, challenging, and well-designed training platform. Thanks for reading!

Martin Hernandez Kipreos
Student of CARTE
I'm excited to share that I've earned the Certified Red Team Expert for Azure (CARTE) certification! by Altered Security. As the integration between AI and Cloud infrastructure accelerates, ensuring these deployments are secure is a must. To effectively protect these complex environments, you must first understand how to attack them. In my day-to-day offensive engagements I encounter misconfigurations that introduce critical risk to the business. This certification has been an excellent way to validate and sharpen my ability to identify, chain, and exploit these Azure-specific attack paths. Looking forward to continuing to help clients stay ahead of advanced threats and secure their cloud perimeters. Shoutout to Nikhil Mittal and Keanu Nys for building an incredible course and a challenging lab and exam environment.
