Supply chain risks remain top-of-mind for the vast majority of CISOs and cybersecurity leaders, according to SecurityScorecard. Their findings reveal that the way most organizations manage supply chain cyber risk isn’t keeping pace with expanding threats.

Third-party involvement in breaches has doubled, rising from 15% to nearly 30%, according to the 2025 Verizon DBIR.
