CRTP (Certified Red Team Professional)
CRTP focuses on assessing the security of an Active Directory environment by abusing features and misconfigurations rather than patchable exploits. It is the certification for Altered Security's Attacking and Defending Active Directory lab, which the issuer describes as its beginner red team certification.
