Sponsored Data and code are the lifeblood of digital organisations, and increasingly these are shared with others in order to achieve specific business goals. As such, data and code must be protected no matter where the workloads run, be they in on-premises data centers, remote cloud servers, or edge-of-the-network.

Take medical images processed in the cloud for example. Their processing must be encrypted for security and privacy. Banks need to share insights into financial data without sharing that underlying confidential data with others. Other organisations may want to process data using artificial intelligence and machine learning but keep secret these learning algorithms that turn data into useful analysis.
