Modern software not only provides new features to help people do their best work, but also new, more efficient manageability solutions and more comprehensive approaches to security. Software that is a decade old or more, and hasn’t benefited from this innovation, is difficult to secure and inherently less productive. As the pace of change accelerates, it has become imperative to move our software to a more modern cadence. By adopting the 5 year period, Office 2021 will help reduce this exposure.
