Kroes calls for better EU cloud security

"A cloud without robust data protection is not the sort of cloud we need. So these features should be well-integrated in the design of cloud-computing products and services, from the very beginning of the business processes," Kroes said on Thursday in a speech at the Les Assises du Numerique conference in Paris.

Data protection standards must also be transnational, she added, noting that "the free movement of personal data within the EU is another way to complete the digital single market in Europe".
