Insurance Carriers Face Unprecedented Supply Chain Cyber Threats

SecurityScorecard’s analysis of 150 leading insurance companies exposes a critical weakness: even carriers with robust security are being compromised through their supply chain partners. Our data reveals that threat actors are deliberately exploiting lower-scoring vendors to breach otherwise well-defended insurance organizations.

Key Findings:

• Third-party breach rate hits record 59% in insurance – more than double the global average, with ransomware dominating the attack landscape
• Insurance carriers outperform vendors in security scores but face heightened risk through weaker supply chain partners
• Cross-industry software vulnerabilities caused 37% of breaches – nearly triple the rate of insurance-specific software issues
• U.S. carriers face disproportionate targeting despite strong security postures, with 79% of multi-breach victims being U.S.-based
