Proof.txt: Offensive Security Certifications, Without the Brochure Voice
A comparison guide to 19 offensive-security certifications, covering exam format, real cost, difficulty, and reporting requirements.
Field notes
Proof.txt groups 19 certifications across eight vendors and emphasizes that vendor choice may determine much of the decision. Its framework separates exam sequencing, preparation references, and report grading rather than treating a certification as a simple badge. The homepage specifically mentions enumeration and Active Directory references, and says its difficulty levels are relative to the certifications in the set rather than to job titles. Individual costs and comparison details are not visible in the extracted homepage text.
