Case Study: Leading Multinational Firm achieves validated security data and continuous vendor-risk visibility with BitSight Security Ratings

Leading Multinational Firm Validates the Quality of the Data from BitSight® Security Ratings

Leading Multinational Firm needed to validate the quality of externally derived security data to improve its vendor risk program and move beyond point-in-time questionnaires and audits. The firm selected BitSight and its BitSight Security Ratings for Vendor Risk Management to determine whether ratings, diligence items, and network maps could provide accurate, continuous, quantitative insight into third‑party security posture.

The firm validated BitSight by correlating a subset of BitSight data with outsourced SIEM event logs and comparing BitSight’s IP maps to vendor and internal network maps, finding no false positives and strong alignment; BitSight’s diligence items also identified configuration and vulnerability issues (e.g., SSL, Bash) that were remediated by network teams. As a result, BitSight delivered continuous visibility, helped prioritize low‑rated vendors, improved vendor communications, and provided KPIs and peer benchmarks the firm now uses to report security posture to leadership and drive remediation.
