Datafari enterprise edition comes out of the box with the SSL protocol activated by default.
The protocol is used on Datafari, Solr, and Kibana which are, according to us, the critical parts of the product concerning the data. Unfortunately, Elasticsearch does not provide a simplest way to use the SSL protocol , so either you have to purchase their "Shield" extension which provides a very easy way to implement security for ES, either you have to manually configure a proxy server.
The following documentation describes how the SSL protocol has been implemented and how you can configure it to fits with your needs.
