Is OSEP worth it? The Crydd Verdict
CS 83Choose it if
You hold OSCP or have the equivalent skills and want to move towards red teaming.
Consider alternatives if
You are not yet at OSCP level: start there. For web applications rather than networks: OSWE.
Why we say so
It is the step after OSCP for testers who need to get past modern defences, and it never expires.
Market demand
Red team and senior penetration testing roles value OffSec credentials highly; OSEP is a common next step after OSCP in those postings.
