WordPress offers multi-site technology. It is the same technology that powers over 20 million sites on WordPress.com and global sites like CNN and the New York Times. Multi-site technology allows users to have full administrative control over their own site, without any security concerns. Each site can have its own look-and-feel (themes), its own functionality (plug-ins), and manage its own users, while at the same time, network-wide policies and security updates can be deployed at the click of a button.
