Ideally there should be some kind of static embedding where you publish in your internet website a kibana dashboard without exposing kibana/elasticsearch to users as it is behing fireall.
When embedding the webite asp.net will download the static embedded url from kibana all static dashboard( html,js, css etc) and put all code into iframe. In this way you can use kibana for nice reporting in your website without allowing users to login in kibana or modify filters, etc
