Executive Summary
AI-generated
A data breach at a vendor or third-party organization can have a significant impact, resulting in unauthorized access to the data of many individuals. According to a report by Kroll, 69% of organizations experienced a data breach in the past year, with more than one-third experiencing multiple breaches. The finance sector accounted for 60% of affected individuals, followed by insurance and healthcare. Cybercriminals often target vendors due to their potential access to large volumes of sensitive information, which can then be exploited by downstream clients. This report highlights the importance of third-party risk management in preventing data breaches, with Kroll's survey revealing that 54% of IT leaders ranked vendors as their biggest compliance risk.
