In her article Why Don’t Companies Just Encrypt All Their Data? Sara Castellanos details the traditional trade-offs that enterprises make between data security and utility.  As she states:

Companies can’t easily perform analysis or machine learning on encrypted data. So at a time when artificial intelligence and real-time data analysis is crucial for competitive advantage, executives must decide what to encrypt and for how long.
— Sara Castellanos, The Wall Street Journal

While citing executives from Microsoft Azure and Box, who acknowledge that "security trumps everything else", she insightfully recognizes that there is a novel approach to this dilemma that  leverages encryption in-use.  "New York-based startup Inpher Inc., for example, has developed technology that enables data to be processed while it remains encrypted, allowing machine learning and analytics to be run without ever exposing the data."
