Hello,
from my side The Denodo server can contain different virtual databases. A virtual database is a schema comprised of data sources, views, stored procedures, web services, etc.Data virtualization is a logical data layer that integrates all enterprise data siloed across the disparate systems, manages the unified data for centralized security and governance, and delivers it to business users in real time.
Denodo relies on contractual agreements, privacy policies, and vendor compliance programs in order to protect data processed or stored by these vendors.The physical and environmental security controls are audited for SOC 2 Type II and[ ISO 27001 Certification](http://iasiso-latinamerica.com/ar/iso-27001-2013-certification/) compliance, among other certifications.This Information Security Management System standard specifies requirements to protect the confidential data and information of the organization
