EY 2026 Data Breach Linked to Third-Party IT Platform
Original: Ernst & Young 2026 Data Breach Analysis: Third-Party IT Support Platform Compromise Exposes Sensitive Client Information
Ernst & Young is facing a data breach in 2026 in which sensitive client information was exposed through a compromised third-party IT support platform. The reported analysis points to weaknesses in supply-chain security rather than EY's own systems. The incident has drawn attention to the risks companies take when granting external IT providers access to sensitive client data.
Why now: A breach at a major professional services firm via a third-party vendor raises fresh concerns about supply-chain cybersecurity.
