Conclusion
Modern digital supply chains have caused reliance on external partners and have led to increased third-party vendor risk. Challenges from network security, DNS health, patching, endpoint protection, and data breach exposure have shown that, when unmitigated, even a single low quality vendor can lead to security concerns that impact the entire organization.
SecurityScorecard enables organizations to use the platform to understand their visibility using focused risk scoring and current threat situational awareness. Organizations can use this information to identify the most vulnerable high risk vendors and decide on issues before they arise.
At this point, the need for external vendor risk management may not be optional, but is a necessity. Organizations that use continuous vendor risk management, predictive vendor risk management, and enhanced vendor risk management will have the edge to lower risk from cyber threats and secure customer confidence across their digital supply chain.
