A technique is disclosed for remotely managing isolated domains on mobile devices. A request is received from the mobile device to instantiate a managed domain. A managed domain configuration is determined and comprises a security policy controlling access to content of the managed domain of the subscribing mobile device, a content specification identifying the content to be downloaded by the subscribing mobile device into the managed domain, and a content configuration identifying a configuration of the content on the subscribing mobile device. The managed domain configuration is sent to the subscribing mobile device to instantiate a secure, managed domain whose policy, content and content configuration is remotely controlled. The technique is useful for advertising and brand promotion on mobile devices as it simultaneously enables detailed control over the presentation of content by a curator while ensuring privacy and security protection of the other apps, accounts and data on the mobile device.
