Offensive Security Certified Professional certification, or OSCP, also focuses on white-hat hacking and penetration testing, though it focuses more on the latter. It’s the lowest-level certification offered by Offensive Security. The IT community recommends OSCP certification for “information security professionals who want to take a serious and meaningful step into the world of professional penetration testing.” OSCP is geared more towards current cyber security professionals, not people who want to start a career in the field.
