The 2019 Cost of a Data Breach Report explores several new avenues for understanding the causes and consequences of data breaches. For the first time, it details the “long tail” of a data breach, demonstrating that the costs of a data breach can be felt for years after the incident. The report also examines organizational and security characteristics that can impact the cost of a data breach, including: the complexity of security environments; operational technology (OT) environments; extensive testing of incident response plans; and the process of closely coordinating development, security, and IT operations functions (DevSecOps).
