Fourth-party visibility—understanding the suppliers and services your vendors rely on—is essential to reducing systemic supply-chain risk. The document explains that breaches often propagate through third- and fourth-party dependencies (highlighting MOVEit/Cleo as common vectors), provides best practices (dependency mapping, enhanced due diligence, breach response prioritization, regulatory readiness), and positions SecurityScorecard’s Supply Chain Detection and Response (SCDR) and MAX managed service as solutions to monitor and remediate these extended risks.
