Testimonials & Student Feedback
"I am happy to share that I have completed and passed AlteredSecurity Certified Penetration Tester (ACPT) exam The course was focusing on Network and active directory penetration testing using Netexec. The course is built by Alexander Neff, a core maintainer of NetExec, so you learn the tooling and the enterprise attack methodology straight from the source. Special thanks to Altered Security and Alexander Neff for this great course and challenge."
"Completing the CRTP certification with Altered Security. The hands-on exam strengthened my practical skills in Active Directory enumeration, privilege escalation, Kerberos attacks, ACL abuse, persistence and domain/forest attacks.
A great experience that significantly strengthened my red team and Active Directory security skills."
"CRTE 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.
