Secure Copy Plugin
Teams in different development groups - usually running different Jenkins masters - need to share artifacts.
They do so by directing the upstream job to place the artifacts in a common area. A team member then manually notifies the team working on the downstream job that the artifacts are available. The result of using a process such as this is that the artifacts are shared manually and insecurely.
The Secure Copy plugin, available with Jenkins Enterprise by CloudBees, allows teams to transfer artifacts securely, automatically and without manual notifications. A key-pair is generated out of band and set up in the sender and receiver jobs. Subsequently, every time an artifact is generated, it is picked up by the downstream job. The artifact cannot be downloaded by anyone else.
