Hightouch can connect directly to services running within your private network, including your data warehouse, self-hosted destinations, and even tools like a private Git server or a customer-hosted Looker deployment.
For added security, considering using an SSH tunnel to layer on public key based authentication and encryption.
Your private network will likely need to be configured to allow connections from Hightouch's systems by modifying your firewall allowlist.
Make sure you configure your network firewalls to allow access from only the IP addresses corresponding to the region you selected when you created your Hightouch workspace.
