All VMware Powered Public Cloud services offer a secure platform. VMware vSphere, a core building block, offers a secure virtualization platform with EAL2+ and FISMA certifications. vCloud Director, a hybrid cloud delivery platform, offers secure multi-tenancy and organization isolation. The vCloud Suite enables service providers to exercise the defense-in-depth security best practice. The platform offers both per-organization edge firewalls and per-VM firewalls with the inclusion of VMware NSX, and all organizations are isolated with their own Layer 2 networks. Access and authentication can optionally be performed against an enterprise organization’s own directory using LDAP or Active Directory. The enterprise can thus self-manage its user base and provide role-based access according to its own policies.
