Data Isolation on ELK data pipeline

Elastic Stack Elasticsearch
1

Hello ,
Can some one speak in to the data isolation part of elastic especially when you have data with different labeling ?
For example I have :
finance data
sales data
users data

I can create spaces for each type of data and then create indexes for each of them but is that the right approach any encryption options available for those type of data. Any other recommenations ?

The approach you described is what you should do, create different users, indices and spaces and roles to access those indices and spaces.

Elasticsearch does not support searching on encrypted data, so there is no encryption option available.
