I am using a non-HIPAA-compliant vendor (Vercel) for the hosting of my site. This includes serverless functions on Vercel's infrastructure that serve HTML/CSS/JS. However, the entire backend/database infrastructure lives in my own AWS account which is properly setup to be HIPAA compliant, per Vanta. I don't intend to have any PHI within Vercel's infrastructure -- the frontend will make calls to the backend but this comes from the user's browser.
Is this a kosher setup for HIPAA compliance? I assume I wouldn't be able to SSR anything that includes PHI, is that correct?
