OSEP
OffSec Experienced Penetration Tester · OffSec
The OSEP validates advanced penetration testing against hardened environments: client-side attacks, antivirus and EDR evasion, Active Directory abuse, credential harvesting, persistence and lateral movement in mature networks. It is the natural follow-up to the OSCP for red teamers and part of the OSCE³ trio. Its strength is a realistic simulation of attacks against defended organisations; its limit is that it focuses on Windows environments and requires a lot of preparation time.
