Case Study: Large Global Insurance Company reduces cyber insurance portfolio risk with BitSight Security Ratings

Global Insurer Uses BitSight® in the Underwriting Process to Reduce Cyber Insurance Portfolio Risk

Large Global Insurance Company, a leading global commercial insurer serving Fortune 1000 and Fortune Global 500 clients, faced the challenge of continuously monitoring and reducing cyber risk across a large insurance portfolio. Questionnaires and self-assessments gave only point-in-time, applicant-controlled views, so the insurer adopted BitSight Security Ratings for Cyber Insurance to independently verify applicant security postures and identify gaps before underwriting.

Using BitSight, underwriters reviewed applicants’ Security Ratings and provided 14-day access to reports so applicants could investigate issues; BitSight’s externally observed metrics (breaches, compromised systems, file‑sharing, patching) enabled continuous monitoring and objective verification. In one case, BitSight’s Enable Client Access revealed a compromised medical device that was remediated within hours, allowing the insurer to approve coverage—demonstrating faster remediation, clearer underwriting decisions, and reduced portfolio risk thanks to BitSight.
