When asked what motives a business to use encryption to protect data in the Cloud, 80 per cent chose internal security policies.

"I was surprised at how many people are motivated to use encryption purely for their own policies," Dietz said.

He said when this question was asked four or five years ago around the world, that was "no way near" the priority for encryption.

"It was the lowest thing on the totem pole," Dietz said.

"But now it has become the culture in IT that they need to have good data compliance, and that is what you want to have."
