Fivetran has extended private networking support for its Business Critical plan to include Databricks, allowing sensitive data to be sent without exposure to the public internet. This feature is particularly beneficial for highly regulated industries like healthcare and financial services. Private networking provides secure communication between Fivetran's cloud environment and a user's Databricks environment, reducing dependency on IT teams and supporting regulatory compliance requirements. The setup process varies depending on whether the Databricks instance is hosted on AWS or Azure.
