What Is Doxing and How Can You Prevent It?

**Executive summary:** Doxing—the malicious exposure of PII via OSINT—poses significant enterprise risk by enabling extortion, reputational damage, operational disruption, and potential physical harm; attackers gather data from public records, social media, credential leaks, and misconfigurations. The report outlines third-party/vendor risks and seven key defenses (minimize digital footprint, enforce credential hygiene/MFA, monitor dark web, train employees on OPSEC, secure and segment PII, etc.) and highlights SecurityScorecard’s Attack Surface Intelligence and Supply Chain Detection and Response (SCDR) as tools to detect and act on exposure signals.
