One of my client is planning to use Elastic SaaS Solution from Elastic on Azure (native Elasticsearch) for document search. It will be storing very sensitive data. So the question is how "secure" an Elastic SaaS solution is. Will it be deployed inside the client's AZure Tenant - if not, how is the communication between Clients Azure Tenant and Elastic SaaS Deployment secured. I had something in mind that the is a kind of "private" VPN CHannel.
Any Iormation about Elastic SaaS Deployment on Azure is welcome
