What is the primary benefit of responsible disclosure?

Correct answer: It gives the vendor time to patch before public disclosure

Option B is correct because the primary purpose of responsible disclosure (also called coordinated vulnerability disclosure) is to give the affected vendor or organization a defined window of time to develop, test, and release a patch before the vulnerability details are made public, minimizing the risk of exploitation. Option A is incorrect because responsible disclosure does not eliminate the need for security testing; continuous testing remains essential regardless of disclosure practices. Option C is incorrect because responsible disclosure is an ethical and coordination framework, not a cost-reduction mechanism for penetration testing engagements. Option D is the opposite of the intent; responsible disclosure is specifically designed to prevent or limit attacker exploitation by ensuring patches are available before full public exposure.
