That is correct. We do not currently offer any general-purpose VPN services, nor do we have any current plans to offer one. In the past, we offered a VPN service specifically for the purpose of connecting securely to DreamHost services; however, we discontinued it several years ago, as existing security protocols such as SSH, SFTP, and SSL serve the same purpose, and are available to all customers.
Our VPS and dedicated servers cannot be used to set up VPN endpoints — sorry. They're not configured to support some of the advanced networking options that are required for this functionality.
Moreover, it's not clear that such a configuration would be HIPAA compliant anyways. DreamHost is not a HIPAA compliant hosting provider; if you are transmitting personal health information that must be encrypted in transit, it will likely need to not pass through our servers at all. If you're unsure whether you're in compliance, I'd highly recommend that you consult with an expert in these matters (which I am not).
