System Center Updates Publisher

The System Center Updates Publisher was built on the custom updates framework that was introduced in Systems Management Server 2003 R2. Updates Publisher is a stand-alone tool that enables independent software vendors or line-of-business developers to import custom software update catalogs, create and modify software update definitions, export update definitions to catalogs, and publish software update information to a configured WSUS server. 

By using Updates Publisher to define software updates and publish them to the WSUS server, the Software Updates feature in Configuration Manager is able to synchronize the custom update from the WSUS server database to the site server database. This will allow you to enable client computers to scan for custom update compliance and to provide administrators with the ability to deploy the custom updates to client computers.
