In order to support and enable the Big Work and the dramatic shift in today's cyber-risk landscape, our security decision-making and implementation processes are shifting from centrally controlled, stage-gated, waterfall approaches to more decentralized and agile methods. Instead of being confined to a centralized authority, risk decisions are to be made at the edge by delegated CISOs using agile processes and cyber judgment.

To facilitate this shift, cybersecurity requires scalable processes that can effectively handle conflicts, excess residual risks, and exception requests. These processes should be able to provide hands-on support at the speed required by the business.

The Global CISO is embracing an approach that involves centrally creating cybersecurity policies and capabilities with input from delegated CISO's. These policies and capabilities are then adapted locally into standards, guidelines, and operating procedures. The "what" is defined centrally, while the "how" is resolved locally.
