Understanding the Importance of Cybersecurity Due Diligence

This SecurityScorecard report outlines the importance of cybersecurity due diligence for assessing third- and fourth-party vendor risk—particularly in M&A—by recommending a framework to measure cyberhealth, benchmark against industry peers, centralize vendor management, apply security frameworks (e.g., NIST), implement mitigations, and continuously monitor vendor portfolios, while positioning SecurityScorecard’s continuous external ratings as a tool to improve and accelerate due diligence.
