The intelligence community (IC) [1] is not part of the JEDI contract [2]. While many IC components are part of DoD, the IC spans a wider swath of government (e.g. parts are distributed across DOJ, DOE, Homeland Security, State, etc). In addition to different mission sets, they are also governed under a different set of laws. Therefore, DoD (like DOJ, DOE, Homeland, etc) systems connect to IC systems to share information, but there are distinct infrastructures whereby neither has full visibility into the other.
