How Barbara is building a better working world

“At EY,  reputation is key. A big part of protecting that reputation is protecting EY  data and that of EY clients while enabling services to work effectively and securely. Each day presents new information security challenges and opportunities, but we strive to continue to demonstrate to EY clients and  regulators that we take our role as data custodians very seriously. By helping to achieve this objective, I believe I am contributing to building a better working world.”
