Hi,

i am relativ new with the ELK Stack. For Security Reasons I need to know, if there is a communication needed FROM Elasticsearch to Fleet Server, Kibana or something else in ELK Stack. We want put our ES Cluster in a separate network where "everybody" can "send" but ES can't send data outside.

Thanks for help!
