"The Jenkins Enterprise software subscription, designed to be
deployed on internal networks, includes formal technical support
and a commitment by CloudBees that the release will be updated for
a full year, which is longer than the three months of upgrades that
the open-source community guarantees for the software.
"In addition to the core Jenkins program, Jenkins Enterprise
also offers a number of additional plugins to aid its use in the
enterprise, including ones that would aid in security, large
installations and usage optimization. Jenkins Enterpriseis based on
the Jenkins Nectar 11.10 release."
